MEAN WELL PID-250 series: Dual-Output Open-Frame AC/DC Power Supply - PID-250D

Description

MEAN WELL PID-250D is a dual-output open-frame AC/DC power supply with 48 V on CH1 and 5 V on CH2. The complete unit is rated 250.6 W, with independently isolated output and return connections for CH1 and CH2. Active PFC, CH1 remote control and model-specific short-duration peak output support equipment integration; apply the cooling and input limits below.

The PID-250 section is on PDF pages 10, 11. Refer to the complete mechanical drawings and notes when planning installation.

Model and Output Configuration

Complete model PID-250D.
Output arrangement CH1: 48 V / 4.7 A; CH2: 5 V / 5 A at the catalogue-rated operating point.
Combined rated power 250.6 W for the complete unit, not for each output.
Output returns CH1 uses COM1 and CH2 uses COM2; the catalogue identifies isolated outputs and grounds.
Factory test 100% full-load burn-in test.

Use both channel limits and the combined-power limit together. The channel current-range maxima are not additional independent power ratings.

CH1 Output Specifications

Nominal voltage 48 VDC.
Rated current 4.7 A.
Current range 0–4.7 A, subject to combined-power and cooling limits.
Peak loading 8.4 A for CH1 for no more than 10 seconds, with the low-input restriction below.
Ripple and noise, maximum 200 mVp-p.
Voltage adjustment 43.2–52.8 V using SVR1.
Voltage tolerance ±2.0%.
Line regulation ±0.5%.
Load regulation ±1.0%.

CH2 Output Specifications

Nominal voltage 5 VDC.
Rated current 5 A.
Current range 0–5 A, subject to combined-power and cooling limits.
Peak loading 5 A; no separate higher CH2 peak rating is specified.
Ripple and noise, maximum 50 mVp-p.
Voltage adjustment 4.75–5.25 V using SVR2.
Voltage tolerance ±2.0%.
Line regulation ±0.5%.
Load regulation ±2.0%.

Combined Loading and Measurement Conditions

Typical efficiency 86%.

Unless otherwise stated, specifications are measured at 230 VAC input, rated load and 25°C ambient. 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.

The listed CH1 peak current is a short-duration limit of no more than 10 seconds, not a continuous operating current. It remains subject to the channel protection behaviour and the input-voltage restriction.

Below 110 VAC input, CH1 peak current must also not exceed 150% of its rated current. Apply the lower of that limit and the tabulated peak value; for this model the resulting limit is 7.05 A, calculated from those two limits.

Input and Timing

Input range 90–264 VAC or 127–370 VDC; 47–63 Hz AC.
Active PFC At full load, PF ≥0.92 at 230 VAC and ≥0.97 at 115 VAC.
Typical AC current 3 A at 115 VAC; 1.5 A at 230 VAC.
Typical cold-start inrush 58 A at 230 VAC.
Leakage current Less than 3.5 mA at 240 VAC.
Set-up / rise time 2500 ms / 60 ms at 115 VAC; 1200 ms / 60 ms at 230 VAC.
Typical hold-up time 30 ms at full load.
Switching frequencies PFC 100 kHz; PWM 100 kHz.

At 60 Hz, allowable load is 80% at 90 VAC, rising to 100% at 110 VAC and remaining at 100% through 264 VAC. Apply the low-input peak-current condition separately.

Protection and Remote Control

CH1 overload 105–170% of rated output power: operation within 10 seconds followed by shutdown; re-power on to recover. Above 180% of rated power or during a short circuit, constant-current limiting operates within 10 seconds, then shutdown; re-power on to recover.
CH2 overload 101–150% of rated output power; hiccup mode with automatic recovery after fault removal.
CH1 overvoltage 54–64.8 V; output shuts down, re-power on to recover.
CH2 overvoltage 5.5–6.75 V; Zener-diode clamp and hiccup protection, with automatic recovery after fault removal.
Overtemperature CH1 shuts down and automatically recovers after temperature falls.
CN52 remote control Pins 1 and 2 open: CH1 and CH2 ON. Pins 1 and 2 shorted: CH1 OFF, CH2 ON.
Channel dependency A CH2 malfunction also shuts down CH1.

Remote control acts on CH1; the open/short input is not a command to turn both outputs off. Keep the two output return arrangements distinct when planning the load wiring.

Environment and Derating

Working temperature −20 to 70°C, subject to the applicable derating curve.
Operating humidity 20–90% RH, non-condensing.
Storage −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, allowable load rises from 80% at −20°C to 100% at −10°C. With natural convection, 100% is available through 40°C, decreasing to 50% at 60°C; the no-fan curve ends at 60°C.

With the illustrated 18 CFM airflow, 100% is available through 60°C, decreasing to 60% at 70°C. The 70°C endpoint is a fan-cooled condition, not a natural-convection rating.

Above 2000 m, reduce allowable ambient temperature by 3.5°C per additional 1000 m with fanless cooling, or 5°C per additional 1000 m with fan cooling. Apply all relevant load and installation limits together.

Mechanical Installation

Overall size, L × W × H 222 × 95 × 40 mm.
Mounting Five Ø3.5 mm holes; corner-hole centres are 212 × 85 mm with 5 mm edge offsets. The drawing also marks a 130 mm bottom-hole location from the left outline. Use the full drawing to locate all five holes.
Tolerance and underside clearance Drawing tolerance ±1 mm; maximum underside projection 3 mm.
Fan arrangement At least 18 CFM from the short-side direction, shown 15 cm away with a 47.5 mm lateral alignment reference.
Grounding CN1 pin 1 is safety ground. For improved EMC, connect M1, M2, M3 and chassis ground electrically.
Heat-sink isolation Do not short HS1, HS2 and HS3 together.
Adjustments and fuse SVR1 adjusts CH1; SVR2 adjusts CH2. Input fuse marking: T6.3A/250V.

Use the complete drawing on PDF page 11 for mounting and airflow. The illustrated external fan has no order code or supplied-parts quantity specified in these pages.

Connections and Mating Parts

AC input CN1 JST B5P-VH or equivalent: pin 1 FG, pins 2 and 4 no pin, pin 3 AC/N, pin 5 AC/L.
Dual output CN51 JST B10P-VH or equivalent: pins 1–3 COM1, pins 4–6 V1 (CH1), pins 7–8 COM2, pins 9–10 V2 (CH2).
CN1 / CN51 mating parts JST VHR housing-family references and JST SVH-21T-P1.1 terminals, or equivalents.

Select the complete VHR or XHP housing reference to match the connector circuit count and wire assembly. These references identify mating parts; no separate cover, bracket or cable-kit order code, or loose-parts inclusion, is specified.

Safety and Electromagnetic Compatibility

Safety approvals UL62368-1, TUV BS EN/EN62368-1 and EAC TP TC004; the cover also identifies IEC62368-1 CB certification.
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, heavy-industry level; EAC TP TC020.

The catalogue EMC test arrangement uses a 360 × 360 mm metal plate, 1 mm thick. Confirm the finished equipment meets the applicable EMC and safety requirements with its actual enclosure, wiring and mounting.

Weight and Reliability

Single-unit catalogue reference weight 740 g, from the explicit per-unit PACKING value; a catalogue reference, not measured net or shipping-parcel weight.
Packing reference 0.74 kg per unit; 18 pieces / 14.3 kg / 0.98 CUFT.
MTBF, minimum estimates 2091.7 thousand hours, Telcordia SR-332 (Bellcore); 150.5 thousand hours, MIL-HDBK-217F at 25°C.
Manufacturer warranty 3 years, subject to applicable terms.
