PRODUCT OVERVIEW

Built for reliable, continuous power delivery.

The HK1200R-S1 provides moderate-capacity multi-rail power in a standardized slot-style assembly. It gives system designers a straightforward way to supply main, peripheral, control, and standby circuits from one serviceable 1200W module while avoiding unnecessary high-power overhead.

A platform using the HK1200R-S1 should budget its paired 45A +12V rails together with +5V, +3.3V, 5VSB, and -12V demands across the complete board set. Mechanical fit in the 265 × 77 × 84 mm slot, pin compatibility, power-up timing, communications, fan airflow, ripple, and per-rail protection all need bench verification.

Its application image covers servers, storage systems, network equipment, and edge computing. The HK1200R-S1 best serves moderate-load multi-output platforms in these fields, where designers can route dedicated rails to boards and peripherals while maintaining clear current margins, stable standby functions, and accessible cooling and maintenance paths.

CORE ADVANTAGES

02

Multi-Channel Output Architecture

This model provides +12V1 / +12V2 / +5V / +3.3V / 5VSB / -12V multi-channel output. Compared with single 12V CRPS power supplies, it is better suited for server platforms that need direct support for multiple voltage rails from one power module.

03

Platinum-Level Efficiency Design

This series has achieved 80 PLUS® Platinum certification , with peak efficiency up to 94.5% . High efficiency helps reduce power loss and heat generation in server platforms that operate continuously in rack or equipment-room environments.

04

Slot-Style Mechanical Structure

With external dimensions of 265 × 77 × 84 mm , the HK1200R-S1 is designed for slot-style server power integration. It is suitable for systems where the PSU is inserted into a defined slot instead of a standard CRPS bay.

05

I²C Communication Support

The unit supports I²C communication , allowing compatible server platforms to support PSU status monitoring, system-level control, and power management functions.

06

Built for Practical Server Deployment

Forced air cooling, IP20 protection level, EN55022 Class A EMI performance, multi-output voltage regulation, and protection functions such as output overvoltage, undervoltage, overcurrent, short circuit, and overtemperature protection help support stable server operation.

POWER DESIGN

Reliability notes for continuous operation.

The HK1200R-S1 focuses on multi-output server power delivery for platforms that require more than a single 12V rail. Its dual 12V outputs and auxiliary voltage rails make it suitable for systems where server boards, backplanes, control circuits, standby modules, and legacy rail requirements need direct power support from the PSU.

  • 1200W rated output supports server boards, storage backplanes, cooling fans, control circuits, and auxiliary modules.
  • The main 12V outputs include +12V1 45A and +12V2 45A, supporting separated 12V load groups.
  • Auxiliary outputs include +5V 38A, +3.3V 24A, 5VSB 3A, and -12V 0.5A.
  • Voltage regulation accuracy is listed as ≤±5%, with ripple and noise controlled at ≤120mVp-p.
  • Efficiency is listed as ≥94%, with the series reaching peak efficiency of 94.5% under Platinum-level performance.
