Telkoor CPCI-AC-6U-500 900-7002-99 Cabinet Power Supply Module

I. Model and Manufacturer Basic Information
Full model: CPCI-AC-6U-500
Original factory component number: 900-7002-99
Brand: Digital Power (Manufactured by Telkoor)
Specification standard: 6U CompactPCI (CPCI) AC hot-swappable power supply, following PICMG 2.11 CPCI power supply specification
Position: Industrial control CPCI chassis complete power supply module, industrial testing equipment, semiconductor detection, ZYGO laser interferometer, old VME/CPCI measurement and control rack dedicated 500W AC input power supply, supports N+1 redundant parallel

Appearance Hardware Structure
6U 8HP standard European card size, front-mounted dual red locking prongs for assisted insertion, supports online hot swapping, no need to power off the entire machine for replacement
Two side-mounted axial flow cooling fans, full aluminum alloy casing with hollow air duct for heat dissipation
Internal standard P47 CPCI backplane power supply connector on the rear; external IEC C14 AC input socket on the rear end
Two status LEDs on the front panel: power normal, fault alarm indicator

Electrical Input Parameters
AC input: wide-range universal AC 85~264V, 47~63Hz, compatible with global power grids
PFC power factor correction: full load PF ≥ 0.98, in line with industrial harmonic standards
Input fuse: built-in 10A fast fuse IEC fuse, prevents front-stage short circuit burnout
Surge current: maximum 50A@230VAC, built-in suppression circuit
IV. Multiple DC Outputs (Total power 500W)
Two main outputs are independently parallel and current-sharing designed, supporting multiple power sources load distribution Table
Output voltage Rated current Adjustment range
+3.3V 80A 3.1~3.5V
+5V 65A 4.8~5.4V
+12V 12A Standard fixed
-12V 1.5A Standard fixed
Load voltage regulation accuracy: ±1% for +3.3V and +5V; ±12V ±4%
Support zero-light-load startup, no need for minimum load

Core Function Characteristics
N+1 redundant parallel connection: active current sharing, O-Ring anti-backflow diode, no circulating current when multiple power supplies are connected in parallel, automatic seamless switching in case of a single unit failure
Full-dimensional protection
OVP overvoltage, OCP overcurrent, OTP overtemperature, short-circuit self-lock protection
Undervoltage lockout, input power loss warning
Hot-swappable safety mechanism: control of insertion and removal sequence to avoid sudden voltage drop on the backplane causing the industrial control board to reset
Heat dissipation requirements: forced air cooling ≥ 300 LFM, long-term stable output at 500W at full load
Conversion efficiency: full load > 80%, excellent energy efficiency at low load

Environmental and Safety Parameters
Operating temperature: 0℃ ~ +70℃; > 50℃ requires reduced rating
Storage temperature: -40℃ ~ +85℃
Protection: IP20 (installed in the cabinet)
Certifications: UL, CE, RoHS industrial safety standards, EMC meets the standards for industrial control / semiconductor clean rooms
Size: 6U height, depth 160mm; net weight of a single unit is approximately 1.4kg

Typical Application Scenarios
Power supply for ZYGO laser interferometer CPCI measurement and control host (precision nanometer measurement equipment)
Industrial control chassis for semiconductor wafer inspection, vacuum coating equipment
DCI / data acquisition station of old CPCI architecture in power and metallurgy
Multi-channel motion control test rack for military and laboratories
Replacement spare parts for various CompactPCI industrial control systems

 Key Points for Maintenance and Replacement
Compatibility distinction
The CPCI-AC-6U-600 of the same series is the 600W version, with the same hardware shape, it can be upwardly replaced; DC input CPCI power supply cannot be interchanged

Only compatible with 6U CPCI PICMG2.11 standard chassis, VME, ordinary PCI/PCIe chassis cannot be used
It is recommended to uniformly use the same model 900-7002-99 for redundant parallel connection units; mixing different power levels will result in imbalance in current sharing
Before replacement, disconnect the AC input, do not leave the power-on state for a long time in the hot-plug state to prevent instantaneous shock from damaging the backplane cards
Fan dust accumulation will trigger over-temperature protection alarms, regularly clean the dust in the air duct
The original factory model of this type has been discontinued, the ones in circulation on the market are all test spare parts from disassembly, before installing, it is necessary to perform unloaded testing of each output voltage of the circuit
