Model and Output Specifications
| Complete model |
CSP-3000-250 |
| Model code |
CSP is the series; 3000 identifies the 3000 W power class; 250 identifies the nominal output voltage in volts. |
| Nominal DC output |
250 V DC / 12 A / 3000 W |
| Specified current range |
0 to 12 A |
| Constant-current region |
125 to 250 V; use the model-specific PC-mode operating-area diagram and the 3000 W limit. |
| Ripple and noise, maximum |
1000 mVp-p. In PV mode, measured with 20 MHz bandwidth using a 12-inch twisted pair terminated with parallel 0.1 uF and 47 uF capacitors. |
| Voltage tolerance / regulation |
Voltage tolerance ±1.0%, including setup, line and load regulation; line regulation ±0.5%; load regulation ±0.5%. |
| Typical efficiency |
92.5% at 230 VAC, rated load and 25°C, the standard catalog measurement conditions unless otherwise stated. |
| Setup / rise / hold-up |
1000 ms setup and 80 ms rise at 230 VAC and full load; typical hold-up time 10 ms at full load. |
Input and Power Factor
| Input range |
180 to 264 VAC or 254 to 370 VDC; AC frequency 47 to 63 Hz. The catalog requires turning off the output when input is below 160 VAC. |
| Power factor |
Built-in active PFC; typical PF ≥0.95 at 230 VAC and full load. |
| Typical AC current |
20 A at 180 VAC; 16 A at 230 VAC. |
| Inrush / leakage |
Typical cold-start inrush 60 A at 230 VAC; leakage current <0.3 mA at 240 VAC. |
| Input load curve |
The static-characteristics plot shows 100% load across the specified 180 to 264 VAC input range at 60 Hz; thermal and installation limits still apply. |
Voltage and Current Programming
| PV / PC selection |
CN1 pins 5 and 6 shorted selects PV (output-voltage programming); open selects PC (output-current programming). Factory setting is PV at maximum output voltage with a jumper cap fitted. Removing that jumper selects PC at the maximum constant-current setting. |
| Built-in adjustment |
SVR2 sets output voltage or the constant-current point over 20% to 100% of the applicable maximum. Select PV or PC first. |
| External programming input |
CN2 pin 5 is PV/PC+ and pin 6 is PV/PC-. Use the catalog DC-voltage input or a 10 V PWM signal at 500 Hz to 1 kHz. Typical port current is 100 uA. These are control inputs, not output-power terminals. |
| External PV range |
37.5 to 250 V maximum. The PV graph spans 1.5 to 10 V external DC input, or 15% to 100% PWM duty, and is marked non-linear. |
| External PC range |
1.4 to 17 A maximum in the model-specific range table. The PC graph spans 0.8 to 10 V external DC input, or 8% to 100% PWM duty, and is marked non-linear. |
| PC operating area |
Programming current above the nominal 12 A requires lower output voltage and must remain inside the PDF operating area and the 3000 W power limit. It does not permit 17 A at the nominal 250 V. |
| Recommended high-performance area |
The shaded PC-mode region on PDF page 38 includes 9 A at 250 V to 12 A at 250 V, then the 3000 W boundary to 17 A at 176.5 V; the diagram extends down to 125 V. Use the complete I-V diagram for the intended operating point; the unshaded allowed area and shaded recommended area are different. |
Protection and Recovery
| Short circuit |
Output shuts down and latches off; re-power to recover. |
| Over-current / overload |
The specification gives 105% to 120% of rated output power. With CN1 pins 5/6 shorted, the factory protection behavior is constant-current limiting followed by shutdown after 3 seconds; re-power to recover. With the jumper removed, protection is continuous constant-current limiting. This jumper also selects PV/PC mode. |
| Over-voltage |
265 to 315 V; output shuts down; re-power to recover. |
| Over-temperature |
Output shuts down. It recovers automatically after the temperature falls, or by re-powering as stated in the catalog. |
| Fan failure |
Fan-failure protection is listed; a steady red indicator identifies a fan fault. Keep the cooling path unobstructed. |
Remote Control, Auxiliary Supply and Alarms
| Remote ON/OFF pins |
CN1 pin 3 = RC; pin 1 = RCG. Use one complete connection circuit from PDF page 40. In examples 2.2(A) and 2.2(B), an open switch means output ON and a closed switch means OFF. Example 2.2(C) reverses that logic: closed = ON and open = OFF. |
| Auxiliary supply |
12 V at 0.4 A. CN2 pin 2 = 12V AUX+; pin 1 = 12V AUXG. The auxiliary output may be used with the catalog remote-control circuits. |
| P OK relay contact |
CN1 pin 7 = P-OK; pin 9 = P-OK GND. Power OK is low (0.5 V maximum at 500 mA); power failure is high or open. An external voltage source and resistor are required; respect the 20 V and 500 mA limits and the 10 W relay-contact limit. |
| P OK2 signal |
CN1 pin 2 = P-OK-2; pin 4 = P-OK-GND-2. The catalog labels this a TTL alarm and shows an open-collector circuit. Power OK is low (0.5 V maximum at 10 mA); power failure is high or open. Use an external voltage source and resistor, maximum 30 V and 10 mA. |
Parallel Operation
| Permitted arrangement |
Up to three CSP-3000 units with built-in active current sharing, using short, large-diameter output wiring. Connect like-polarity CS+ and CS- signals together; do not reverse them. |
| Current-sharing pins |
CN1 pin 8 = CS+; pin 10 = CS-. |
| Constant-voltage parallel mode |
Keep the difference between unit output voltages below 0.2 V, fine-tuned with SVR1. Maximum combined current = rated current per unit × number of units × 0.9. Below 50% rated current per unit × number of units, current sharing may not be fully balanced. PV and PC programming are unavailable in this mode. |
| Constant-current parallel mode |
Each unit must carry no more than 90% of its rated power. PC can be used; PV is unavailable. Apply each unit's voltage/current operating area and all thermal limits. |
| System power planning |
The family headline is up to 9000 W (2+1), but the detailed parallel-operation limits require the 0.9 factor or 90% per-unit power condition. Do not treat three 3000 W nameplates as an unrestricted 9000 W continuous installation. |
Cooling and Environment
| Cooling |
Forced air from built-in DC fans with fan-speed control; airflow runs from the fan end toward the terminal end as drawn. Conformal coating is listed for this catalog version. |
| Operating temperature / derating |
-20 to +65°C. For horizontal mounting, the curve shows 100% load through +50°C, reducing to 50% load at +65°C. The upper ambient limit is not a full-load rating. |
| Altitude derating |
Above 2000 m (6500 ft), the catalog specifies 5°C per 1000 m ambient derating for fan-cooled models such as CSP-3000. This note does not state an unlimited operating altitude. |
| Humidity / storage |
Operating humidity 20% to 90% RH, non-condensing. Storage -40 to +85°C and 10% to 95% RH, non-condensing. |
| Temperature coefficient |
±0.05%/°C over 0 to +50°C. |
| Vibration |
10 to 500 Hz, 2G; 10 minutes per cycle, 60 minutes along each of X, Y and Z axes. |
Dimensions, Mounting and Power Terminals
| Body dimensions |
278 × 177.8 × 63.5 mm (L × W × H); case 982B, drawing tolerance ±1 mm. Height is also described as 2U. Allow additional clearance for terminals, cables and airflow. |

Pin 1 = AC/L; pin 2 = AC/N; pin 3 = protective ground (FG). Maximum terminal mounting torque 18 kgf·cm. |
| DC output terminal |
Pin 1 = V-; pin 2 = V+. Maximum terminal mounting torque 18 kgf·cm. Check the physical pin orientation against PDF page 44. |
Control Connectors and Mating Parts
| CN1 board connector |
HRS DF11-10DP-2DS or equivalent, 10 positions. |
| CN1 mating housing |
HRS DF11-10DS or equivalent. One mating housing is required to connect this 10-position interface; the number of fitted contacts depends on the functions wired. |
| CN2 board connector |
HRS DF11-8DP-2DS or equivalent, 8 positions. |
| CN2 mating housing |
