Model-Specific DC Output

Nominal output 5 V DC.
Rated continuous output 15 A / 75 W, subject to the cooling and temperature limits.
Catalogue 10-second peak-load limit 82.5 W.
Specified current range 0–16.5 A; continuous loading remains limited by the rated current and power.
Ripple and noise, maximum 80 mVp-p.
Output-voltage adjustment 4.75–5.5 V using SVR1.
Voltage tolerance ±3.0%.
Line / load regulation ±1.0% / ±3.0%.
Efficiency, typical 77%.

Peak loading is limited to 10 seconds and a maximum 33.3% duty cycle within every 30 seconds. Average output power must not exceed the rated power; apply the model-specific current, power and thermal limits together.

Unless stated otherwise, specifications are measured at 230 VAC, rated load and 25°C. Ripple/noise uses 20 MHz bandwidth and a 12-inch twisted pair terminated with parallel 0.1 µF and 47 µF capacitors. Voltage tolerance includes set-up tolerance, line regulation and load regulation.

Input and Operating Features

Input range 90–264 VAC or 127–370 VDC; AC frequency 47–63 Hz.
Input current, typical 1.9 A at 115 VAC; 1.1 A at 230 VAC.
Cold-start inrush, typical 18 A at 115 VAC; 36 A at 230 VAC.
Leakage current Less than 1 mA at 240 VAC.
Set-up / rise time 200 / 35 ms at both 230 VAC and 115 VAC, full load.
Hold-up time, typical 60 ms at 230 VAC; 12 ms at 115 VAC, full load.
Switching-frequency reference 60 kHz in the block diagram.
Power indication Built-in power-on LED.
Production test 100% full-load burn-in test.

Protection

Short circuit / overload 115–150% of rated output power; hiccup mode with automatic recovery after the fault is removed.
Overvoltage 5.75–6.75 V; hiccup mode with automatic recovery after the fault is removed.

Remote ON/OFF Control

Control function Built-in remote ON/OFF control via CN3.
ON / OFF level RC+ relative to RC−: 0–0.8 V turns the output on; 4–10 V turns it off.
CN3 pin assignment Pin 1 RC+; pin 2 RC−.
Connector and mating references JST B2B-XH or equivalent; JST XHP housing family with JST SXH-001T-P0.6 contacts or equivalents.

Select the mating housing for the two-circuit connector and the appropriate wire size. The listed mating references do not establish inclusion of a separate control cable or loose mating parts.

Cooling, Derating and Environment

Operating temperature -20–70°C; allowable load follows the horizontal-installation curve.
Cooling Free-air convection. Keep the ventilation path clear and apply the curve for the actual installation.
Natural-convection curve Full load from −20°C through 40°C, then decreasing to 60% at 60°C.
18 CFM forced-air curve Full load from −20°C through 60°C, then decreasing to 80% at 70°C. This extension requires the specified external airflow.
Static-characteristic chart The separate 15 V chart plots output voltage and ripple against input voltage at 60 Hz; it is not an additional load-rating curve for every model.
Working humidity 20–90% RH, non-condensing.
Storage Temperature -20–85°C; humidity 10–95% RH.
Temperature coefficient ±0.04%/°C over 0–50°C.
Vibration 10–500 Hz, 2 G; 10 minutes per cycle, 60 minutes along each X, Y and Z axis.
High-altitude temperature adjustment Above 2000 m, reduce allowable ambient temperature by 3.5°C per 1000 m for fanless operation or 5°C per 1000 m for fan-cooled operation.

Apply the input-voltage and temperature limits together; a wide operating-temperature range does not mean full power at every temperature.

Dimensions, Grounding and Connections

Dimensions, L × W × H 222 × 55 × 30 mm; drawing tolerance ±1 mm.
Mounting layout Four Ø3.8 mm holes; indicated mounting-centre spacing 212 × 45 mm. The drawing shows up to 3 mm projection below the board.
On-board AC fuse marking F4A / 250 V.
Safety grounding Grounding is required; CN1 pin 5 is safety ground (FG).
AC input CN1 JST B5P-VH or equivalent: pin 1 AC/L; pins 2 and 4 no pin; pin 3 AC/N; pin 5 FG.
DC output CN2 JST B6P-VH or equivalent: pins 1–3 −V; pins 4–6 +V.
Input / output mating references JST VHR housing family and JST SVH-21T-P1.1 contacts, or equivalents.

Choose complete mating housings by circuit count and wire size. Mating housings, contacts and any external fan should be specified separately; the connector reference table does not state that loose mating parts are supplied. Follow the manufacturer installation instructions and maintain the required safety clearances.

Safety, EMC and Isolation

Listed safety approvals UL62368-1, TUV BS EN/EN62368-1 and EAC TP TC004.
Withstand voltage Input–output 3 kVAC; input–FG 2 kVAC; output–FG 0.5 kVAC.
Insulation resistance Input–output, input–FG and output–FG: 100 MΩ at 500 VDC, 25°C and 70% RH.
Emissions BS EN/EN55032 (CISPR32) Class B; BS EN/EN61000-3-2 and -3; EAC TP TC020.
Immunity BS EN/EN61000-4-2, -3, -4, -5, -6, -8 and -11; BS EN/EN55035 and BS EN/EN61000-6-2 (EN50082-2), heavy-industry level, criteria A; EAC TP TC020.

The power supply is a component for installation in final equipment. EMC testing uses a 360 × 360 mm metal plate, 1 mm thick. Confirm that the completed installation satisfies the applicable EMC and safety requirements.

Weight, Reliability and Catalogue

Single-unit reference weight 300 g (0.3 kg), explicitly listed per unit under PACKING; not the carton weight.
Carton packing 48 pieces / 15.6 kg / 1.23 CUFT.
MTBF, minimum estimates 3180.0 thousand hours under Telcordia SR-332 (Bellcore); 608.7 thousand hours under MIL-HDBK-217F at 25°C.
Warranty 2-year manufacturer warranty, subject to applicable terms.
Catalogue revision LPS-75-SPEC, 2024-10-30; combined PDF pages 3–4.
