Description

Key Technical Specifications:

Model: PSMU-350-3 (also referenced as CPCI-350Q-P-38 variant)
Input Voltage: 85–264 VAC, 47–63 Hz (universal); optional 12–36 VDC on some builds
Output Rails & Currents (typical):
- +3.3 VDC @ 60 A max
- +5 VDC @ 50 A max
- +12 VDC @ 15 A max
- -12 VDC @ 2 A max
- +5 VSB (standby) @ 3 A
Total Output Power: 350 W continuous (380 W peak for 10 s)
Efficiency: ≥82% @ full load, typically 85%
Load / Line Regulation: ±0.5% line, ±1% load
Isolation Voltage: 3000 VAC input-output (1 min), 500 VAC output-output
Protections: OVP, OCP (independent per rail), OTP, auto-recovering SCP
Hot-Swap: PICMG 2.11 compliant hot-swap with inrush limiting & backplane sequencing
Remote Management: Optional PMBus monitoring (voltage, current, temp, fault status)
Redundancy: Supports N+1 parallel for no-break operation
Indicators: PWR (green), RED (yellow — redundancy status), ERR (red), per-rail green LEDs
Cooling: Passive heatsink (fanless) — requires chassis airflow
Operating Temp: -40°C to +70°C (no derating startup from -40°C; consult load curve)
MTBF: ≥800,000 h (MIL-HDBK-217F, 25°C)
Compliance: UL 60950-1, CE, CB, RoHS; EMC per EN 55022Class B
Mechanical: 6U × 8HP (approx. 261.6 × 160 × 40.4 mm) CPCI form factor; 64-pin power connector per IEC 61076-4-101

Applications: CPCI-based data acquisition chassis, military/aerospace rugged embedded computers, telecom node equipment, industrial test & measurement PXI/cPCI systems.

Installation & Notes: Insert into CPCI backplane — ensure chassis provides adequate forced airflow over supply heatsink area. For redundant config, populate adjacent slot and enable load sharing via OR-ing. Do not exceed total 350 W combined rail loading. Verify +5 VSB presence before system boot if used for wake-on-LAN / remote management.
