HIMA PS1000/230 (010) Power Module (Special for H41q/H51q)

PS1000/230 (Model: PS1000/230 010, Order Number: 982200089) is a 230VAC input, 24VDC output redundant power module designed by Germany HIMA for the H41q/H51q (HIQuad X) safety system. It is a 19-inch 1U rack-mounted device, providing SIL3-level isolated regulated power supply for the CPU and I/O cards. It has been discontinued but has a large amount of inventory / second-hand available.

VII. Differences from alternative model PS2000/230

PS1000/230 (old model): 1000W, 40A, single fan, discontinued, original equipment H41q/H51q

PS2000/230 (new model): 2000W, 80A, dual redundant fans, hot-swappable, compatible with H41q/H51q/HIMax, in stock

VI. Application and Installation

Typical application: Power supply for the entire HIMA H41q/H51q security system, with CPU, communication card, I/O card, fan module (K9203/K9203A/K9212)

Installation: 1U position in 19-inch rack, leave ≥50mm clearance between top and bottom for heat dissipation; **Supports redundant parallel connection (2 units)** to enhance reliability

Wiring: AC input ≥2.5mm², DC output ≥4mm², single-ended grounding of shield layer

VII. Common Faults and Maintenance

Red light constantly on: Overvoltage / undervoltage of output, overtemperature, fan stop rotation → Power off for inspection of load / heat dissipation / fan

DC OK disconnected: Output abnormal → Measure DC voltage, troubleshoot short circuit / overload

High noise: Dust accumulation on fan → Power off for dust removal or replace fan

Maintenance cycle: Clean every 6 months, check fan speed, test alarm circuit
