Model and output ratings

Model and communication version	DRP-3200-48; Standard PMBus version, identified by the blank communication suffix.
Output voltage and current	48 V DC; rated current 67 A; current range 0–67 A.
Rated output power	3216 W. Apply input-voltage, ambient-temperature and output-programming derating.
Built-in voltage adjustment	47.5–58.8 V DC by the built-in potentiometer; separate from external PV programming.
Voltage tolerance and regulation	Voltage tolerance ±1.0%, including setup tolerance, line regulation and load regulation. Line regulation ±0.5%; load regulation ±0.5%.
Ripple and noise	480 mVp-p maximum, measured at 20 MHz bandwidth with a 12-inch twisted pair terminated by parallel 0.1 µF and 47 µF capacitors. Under variable load or parallel operation, ripple can exceed this value at light load and returns to the normal level above 5% load. PV programming can also slightly increase ripple under some conditions.
Setup, rise and hold-up times	Setup 1500 ms and rise 60 ms at 230 V AC and full load. Typical hold-up time: 16 ms at 230 V AC and 75% load; 9 ms at 230 V AC and full load.
Typical efficiency	94.5% measured at 75% load; reference input 230 V AC and ambient temperature 25°C.

Input and cooling

Input voltage and frequency	90–264 V AC or 127–370 V DC; AC frequency 47–63 Hz.
Input-voltage derating	The 60 Hz input curve permits full rated output at 180–264 V AC and 50% at 90 V AC. At 90 V AC this model is limited to 1608 W and 33.5 A; use the curve between 90 and 180 V AC. Also observe the delivered module/rack nameplate when selecting the allowable load.
PFC and input current	Built-in active PFC. Typical power factor 0.97 at 230 V AC and full load. Typical AC current 17 A at 230 V AC.
Inrush and leakage current	Typical cold-start inrush: 55 A at 230 V AC. Leakage current: less than 1.5 mA at 230 V AC.
Switching frequencies	Block-diagram frequencies: PFC 110 kHz; PWM 90 kHz.
Fan cooling and airflow	Forced-air cooling by the built-in speed-controlled DC fan. The mechanical drawing shows airflow from the front indicator/handle side toward the rear connector; maintain that airflow path.

Protection and output control

Overload protection	105–115% of rated current. Constant-current limiting is followed by output shutdown after 5 seconds; after the output voltage falls, reapply power to recover.
Low-output-voltage shutdown	The output shuts down if output voltage remains below 80% of Vset for 5 seconds; reapply power to recover. Short-circuit protection is listed among the built-in protection functions.
Overvoltage protection	63–75 V; output shuts down and requires power to be reapplied for recovery.
Overtemperature protection	Output shuts down and recovers automatically after the temperature decreases.
Remote and local sense	Remote sense compensates up to 0.5 V of load-wiring drop. Connect +S (pin 30) to load positive and −S (pin 31) to load negative, using twisted sense pairs. Without remote sense, connect pin 30 to +V(signal), pin 28, and pin 31 to −V(signal), pin 29.
Output voltage programming (PV)	Apply an external DC control voltage between PV (pin 27) and −V(signal) (pin 29) to adjust output from 50% to 125% of nominal. The curve shows 50% output at 1 V control and 125% at 4.7 V; 0.4–1 V holds at 50%, while the segment below 0.4 V is shown at 100%. Follow the complete programming curve rather than assuming a 0–5 V linear response.
Current limit with PV adjustment	The PV derating curve shows an 80% current limit at 50–90% nominal output voltage, 100% current at 95–100% nominal voltage, and 80% current at 125% nominal voltage. Apply the intervening curve and the model power rating.
Constant-current level programming (PC)	Apply external DC control between module PC (pin 26) and −V(signal) (pin 29) for a 20–100% rated-current setting. The curve shows 20% at 1 V and 100% at 4.7 V and is explicitly non-linear. The 0.4–1 V segment holds at 20%; below 0.4 V it is shown at 110%. Very low current settings can increase current ripple. DRP operation at constant-current level for more than 5 seconds triggers overload shutdown; this is not an indefinitely sustained constant-current mode.
Remote ON/OFF	Short Remote ON/OFF (pin 17) to +5V-AUX (pin 13) to enable the output; open the connection to disable it. Electrical signal levels are 4.5–5.5 V for ON and −0.5 to +0.5 V for OFF, referenced to GND-AUX. Maximum input voltage is 5.5 V.

Communication and system integration

Communication interface	Built-in I²C interface with PMBus Rev. 1.1, maximum 100 kHz bus speed, for information reading, status monitoring and output trimming. Pin 14 is SCL and pin 15 is SDA, referenced to GND-AUX (pin 12).
Current sharing and racks	Active current sharing and OR-ing FETs support redundant and hot-swap systems. The series catalog describes up to 12,800 W in one DHP-1UT shelf and 25,600 W across two shelves; these are system-level figures, not one module’s rating. Use identical models with the same output voltage/current, no more than four per shelf or eight across two DRP shelves, and observe each module’s ratings and system derating. Communication address capacity does not increase this physical parallel limit. For more than one rack in parallel, the manual specifies return to normal ripple above 10% of total rated load.
Referenced system accessories	The catalog identifies the DHP-1UT 19-inch rack shelf and RKP-CMU1 control/monitor unit as available separately. Their mention does not mean that either accessory is included with this module.
Applications and factory options	Manufacturer-listed applications include industrial automation, distributed power, wireless/telecommunications, redundant power, electric-vehicle charger systems and constant-current source systems. Conformal coating is an optional factory configuration; confirm it when ordering.

Connector, auxiliary outputs and alarms

Connector identification	Module CN1: Positronic PCIM34W13M400A1; mating housing: PCIM34W13F400A1. The following pin numbers refer to this 34-position module connector. The rack shelf has different CN1/CN2/JK1 connectors; follow the matching module or shelf drawing and its connector-view orientation.
Main power connections	Pins 1, 2, 3, 4 and 6: −V. Pins 5, 7, 8, 9 and 10: +V. Pin 32: FG; pin 33: AC/L; pin 34: AC/N.
Signal connections	Pin 24: DB; pin 25: DA, for differential parallel control. Pin 26: PC; pin 27: PV; pin 28: +V(signal); pin 29: −V(signal); pin 30: +S; pin 31: −S. The +V(signal) and −V(signal) terminals are not load-power terminals and must not be connected directly to the load.
PMBus address pins	Pins 20, 21, 22 and 23 are A3, A2, A1 and A0 respectively; these address signals are referenced to −V(signal).
Signal reference separation	Parallel control and PV/PC use non-isolated signals referenced to −V(signal). The communication, remote-control and alarm signals are isolated and referenced to GND-AUX. GND-AUX is isolated from the main +V/−V outputs.
Auxiliary power	Pin 12: GND-AUX. Pin 13: 5 V / 0.3 A maximum, ±10% tolerance (4.5–5.5 V), ripple 150 mVp-p. Pin 11: 12 V / 0.8 A maximum, ±10% tolerance (10.8–13.2 V), ripple 450 mVp-p. Both auxiliary outputs have built-in OR-ing diodes and remain available independently of Remote ON/OFF.
Temperature alarm	Pin 16, T-ALARM: high (3.5–5.5 V) when the internal temperature exceeds the alarm limit or the fan fails; low (−0.5 to +0.5 V) when temperature and fan operation are normal.
DC and AC alarms	Pin 18, DC-OK: high (3.5–5.5 V) when Vout is at or below 77% ±5%; low (−0.5 to +0.5 V) when Vout is at or above 80% ±5%. Pin 19, AC-OK: high at input ≥87 V rms and low at input ≤75 V rms, with the same high/low signal levels. T-ALARM, DC-OK and AC-OK are isolated TTL output-only signals, each sourcing no more than 10 mA.
Status indicator	Green: normal operation. Steady red: abnormal status such as overtemperature, overload or fan failure. Flashing red: internal temperature has reached 60°C; the module still operates normally without entering overtemperature shutdown. The manual also specifies a temperature alarm through the installed PMBus or CANBus interface.

Environment and installation dimensions

Module and rack temperature curves	Module operating range: −30°C to +70°C. The DRP datasheet horizontal curve shows full load through +50°C and 50% load at +70°C. The rack-system manual instead shows full load through +40°C and 50% at +70°C, and specifically limits three or four parallel modules in a shelf to +40°C at full load. Apply the more restrictive rack-manual curve for rack installation and confirm the finished system’s thermal design. Both curves restrict −30°C to −25°C operation to 230 V AC input.
Altitude derating	Above 2000 m (6500 ft), reduce allowable ambient temperature by 5°C per 1000 m for this fan-cooled model.
Humidity and storage	Working humidity: 20–90% RH, non-condensing. Storage: −40°C to +85°C and 10–95% RH, non-condensing.
Temperature coefficient and vibration	Temperature coefficient ±0.03%/°C over 0–50°C. Vibration: 10–500 Hz, 2G; 10 minutes per cycle, 60 minutes along each of the X, Y and Z axes.
Dimensions and mounting drawing	325 × 107 × 41 mm (L × W × H), 1U profile; case No. 256. Drawing tolerance ±0.5 mm. The drawing identifies M4 fixing positions with L = 5 mm, and additional connector/front protrusions of 11 mm maximum and 10 mm maximum; allow installation clearance using the complete drawing.
Unit weight and packing reference	2.65 kg (2650 g), catalog packing reference per unit. The separate carton reference is 4 pieces / 11.6 kg / 0.87 CUFT; carton gross weight is not the unit weight.

Isolation, compliance and manufacturer references

Safety standards	UL 62368-1, CSA C22.2 No. 62368-1, TUV BS EN/EN62368-1 and EAC TP TC 004 approved. The catalog also displays CB, CE and UKCA markings.
Withstand voltage and insulation	Input-to-output 3 kV AC; input-to-FG 2 kV AC; output-to-FG 1.5 kV AC. Insulation resistance for these three paths: 100 MΩ at 500 V DC, 25°C and 70% RH.

Reliability and warranty references	MTBF: 535,500 hours minimum, Telcordia SR-332 (Bellcore); 44,600 hours minimum, MIL-HDBK-217F at 25°C. The manufacturer catalog states a 5-year warranty.
Reference test conditions	Unless otherwise specified, parameters are measured at 230 V AC input, rated load and 25°C ambient. Efficiency is separately measured at 75% load.

Installation and operating guidance

Rack mounting and airflow	Install the module in a compatible DHP-1U shelf mounted in a 19-inch rack cabinet before operation. Use 1–4 identical modules with the same output voltage and current. Keep fan openings unobstructed; the manual recommends no barriers within 10 cm of ventilation holes.
Protective earth and service	Connect the rack frame ground securely to protective earth. Have faults examined by a qualified technician; do not remove the case or modify internal components. Avoid moisture, high ambient temperature and direct sunlight.
Rack temperature limit	The module datasheet and rack-system manual show different thermal curves. For the rack installation, use the manual full-load limit of 40°C and derate above it; this limit is explicitly required when 3 or 4 modules operate together. Apply input-voltage and ambient-temperature derating together.
Wiring selection	Supply the occupied AC inlets individually. Select copper conductors and protective devices for the actual nameplate current, module count and installation conditions; the manual wire table is a reference, not a universal cable rating for every operating point.
Restart interval	The manual recommends a 10-second cool-down interval after switching off before applying power again, so the inrush-limiting thermistor can cool. After overvoltage protection trips, leave the unit off for 10 seconds before recycling AC.
Sense wiring in the rack	Use twisted or shielded sense wires and keep load-wire voltage drop below 0.5 V. If remote sense is unused, connect +S to +V (signal) and −S to −V (signal) for local sensing. Signal terminals must not carry load current. Use the DRP remote-sense harness rather than the DBR temperature-sensor harness.
Parallel rack operation	Parallel only identical DRP units with matching output voltage and current. The manual permits up to 2 rack shelves and 8 modules, recommends reducing total output current by 10%, and requires output-voltage difference below 0.2 V. Interconnect the shelves before connecting the load and follow the DA/DB/−V and sense wiring diagram. Multi-rack light-load ripple can exceed the nominal specification.
Control priority and timeout	Communication control takes priority over PV/PC, which takes priority over SVR. During communication control, communicate with the unit within each 4-second interval. The manual describes control-priority reset on communication timeout; when D0 is set to 1, timeout or AC recycling also returns some communication parameters to factory defaults. Check the required output settings before enabling the load.
Series connection limit	For a series rack arrangement, use identical units, keep total rated output voltage below 60 V DC, and do not exceed the output-current capability of either shelf. The manual recommends external reverse-voltage protection diodes with ratings above the total output voltage and current.
EMC integration	The DRP module catalog EMC tests use a 600 × 900 × 1 mm metal plate. Reconfirm EMC in the finished equipment with the installed module and connected load; application, wiring and assembly affect the result. The linked EMI guidance describes representative testing, not installation clearances.
PMBus communication	Use PMBus Rev. 1.1 at up to 100 kHz with a unique DRP address. A0–A3 provide 16 addresses; DIP ON=0 and OFF=1. Insert at least 50 ms between commands. VOUT_COMMAND is read-only; output voltage is changed through VOUT_TRIM.
PMBus voltage setting	The DRP PMBus table lists VOUT_TRIM −24 to +12 V, giving an output range of 24–60 V for the 48 V model. Remain within the module rated power/current and applicable derating limits.
Current readback limitation	READ_IOUT can report zero below the manual minimum readable-current threshold of 2.7 A ±1 A. A zero communication reading does not establish that the output carries no current.
