Model and Cooling Selection

Complete model LPP-150-7.5.
Series LPP-150 single-output switching power supply with active PFC.
Rated cooling condition 18 CFM forced airflow; apply the temperature and input-voltage curves.
Natural convection Permitted at the reduced load shown in the no-fan curve.
Optional protection Overtemperature protection is optional; confirm the required configuration before ordering.

The catalogue specifies 100% full-load burn-in testing and a three-year manufacturer warranty. Use the complete model and required options when selecting the supply.

Output Specifications

Nominal output 7.5 VDC.
Rated current 20 A with the specified cooling.
Current range 0–20 A, subject to the applicable load limit.
Rated power 150 W with 18 CFM airflow at full-rating conditions.
Natural-convection limit through 40°C 16 A / 120 W, calculated from the 80% curve; low-input and other thermal restrictions still apply.
Maximum ripple and noise 100 mVp-p.
Voltage adjustment 7.13–8.25 V using +V ADJ.
Voltage tolerance ±2.0%.
Line regulation ±0.5%.
Load regulation ±1.0%.
Typical efficiency 80%.

Unless otherwise specified, parameters are measured at 230 VAC input, rated load and 25°C ambient. Ripple/noise is measured with 20 MHz bandwidth and a 12-inch twisted pair terminated by parallel 0.1 μF and 47 μF capacitors. Voltage tolerance includes setup tolerance, line regulation and load regulation.

Input and Timing

Input range 85–264 VAC or 120–370 VDC.
AC frequency 47–63 Hz.
Power factor at full load At least 0.96 at 230 VAC and at least 0.97 at 115 VAC.
Typical AC input current 2.5 A at 115 VAC; 1.2 A at 230 VAC.
Typical cold-start inrush 55 A at 230 VAC.
Leakage current Less than 3.5 mA at 240 VAC.
Setup / rise time 600 ms / 30 ms at full load.
Typical hold-up time 30 ms at full load.
Switching frequencies PFC: 67 kHz; PWM: 134 kHz.

At 60 Hz, the input-voltage curve allows 80% load at 85 VAC, increasing to 100% at 100 VAC and remaining at 100% through 264 VAC. Apply the lower of the input and cooling limits.

Protection

Short circuit and overload 105–150% of rated output power; constant-current limiting with automatic recovery after the fault is removed.
Overvoltage threshold 8.25–10.1 V.
Overvoltage recovery Output shuts down; re-power on to recover.
Overtemperature option Available as an option. Confirm its inclusion for the ordered configuration; the catalogue does not state a trip temperature or recovery condition.

Environment and Derating

Operating humidity 20–90% RH, non-condensing.
Storage temperature and humidity −20 to +85°C; 10–95% RH.
Temperature coefficient ±0.05%/°C over 0–50°C.
Vibration 10–500 Hz, 2 G; 10 minutes per cycle and 60 minutes along each X, Y and Z axis.

For horizontal installation with 18 CFM airflow, allowable load is 80% at −10°C, rises to 100% at 0°C, remains at 100% through 50°C and decreases to 80% at 60°C. The fan-cooled operating range is −10 to +60°C.

With no fan, the curve allows 80% load from −10 to +40°C, then decreases to 60% at +50°C. The no-fan curve ends at 50°C; do not apply the fan-cooled 60°C endpoint to natural convection.

For this 3.3–7.5 V model group below 100 VAC input with no fan, reduce the load to no more than 60% of the rated output. This additional low-input restriction applies together with the temperature curve.

For installation above 2000 m, reduce the permitted ambient temperature by 3.5°C per additional 1000 m without a fan, or by 5°C per additional 1000 m with fan cooling. Confirm the installation requirements for the intended altitude.

Mechanical Installation

Overall dimensions (L × W × H) 222 × 75 × 41 mm.
Drawing tolerance ±1 mm.
Mounting holes Four Ø3.8 mm holes, 212 × 65 mm centres, with 5 mm edge offsets.
Underside reference 3 mm maximum projection below the board; allow the required clearance.
Forced-air arrangement The drawing shows an external 18 CFM fan 15 cm from the long side, with a 111 mm lateral alignment reference. Follow the illustrated airflow direction.
Grounding Grounding is required. CN1 pin 5 is the safety-ground connection; connect the marked grounding points as shown.
Input fuse marking AC F5A/250V, as marked in the mechanical drawing.

The cooling illustration does not specify a fan order code or confirm that a fan is supplied. Use the complete mechanical drawing on PDF page 12 for mounting, polarity and +V ADJ. access.

Connections and Mating Parts

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 / safety ground.
DC output CN2 Two JST B6P-VH connectors or equivalent, shown as B6P-VH × 2: pins 1–6 are −V; pins 7–12 are +V.
Mating housings and contacts Both connector groups list JST VHR housing-family references and JST SVH-21T-P1.1 terminals, or equivalents.

Select the complete VHR housing reference to match the required circuit count and wire assembly. The catalogue does not identify a separate cover, mounting-bracket or cable-kit order code; do not assume an unlisted kit or loose mating parts are included.

Safety and Electromagnetic Compatibility

Safety approvals UL62368-1 and TUV BS EN/EN62368-1; 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.

Immunity BS EN/EN61000-4-2, -3, -4, -5, -6, -8 and -11; BS EN/EN55035, light-industry level; EAC TP TC020.

EMC testing uses a 360 × 360 mm metal plate, 1 mm thick. The supply is an installation component; re-confirm safety and EMC compliance in the finished equipment with its actual mounting and wiring.

Weight, Reliability and Catalogue

Single-unit catalogue reference weight 620 g (0.62 kg), from the explicit per-unit PACKING value; a catalogue reference, not a measured net or shipping-parcel weight.
Packing reference 24 pieces / 16.6 kg / 1.63 CUFT.
MTBF, minimum estimates 2635.3 thousand hours, Telcordia SR-332 (Bellcore); 292.7 thousand hours, MIL-HDBK-217F at 25°C.
