PRODUCT OVERVIEW

Built for reliable, continuous power delivery.

The HK2200R-S1 is a high-capacity slot-style power supply built around dual 12V channels and several auxiliary rails. Its 2200W architecture helps complex platforms centralize multi-voltage delivery, reduce separate conversion hardware, and retain a replaceable module structure for ongoing service.

The HK2200R-S1 requires detailed allocation of its dual +12V rails—145A and 108A—alongside +5V, +3.3V, 5VSB, and -12V outputs. Check the 265 × 77 × 84 mm slot envelope, connector pin map, cross-rail limits, I²C monitoring, airflow, protection coordination, and startup sequence with the actual server backplane.

Servers, storage systems, network equipment, and edge computing are the application areas pictured for the HK2200R-S1. Its 2200W multi-rail design is appropriate for heavily populated platforms in those categories, where separate board and peripheral loads must be distributed deliberately and verified during redundancy and thermal testing.

02

Multi-Channel Output Architecture

This model provides +12V1 / +12V2 / +5V / +3.3V / 5VSB / -12V multi-channel output. Compared with single-output CRPS models, it is more suitable for server designs that require several direct DC rails from the 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 under heavy workloads.

04

Long Slot-Style Structure

With external dimensions of 265 × 77 × 84 mm , the HK2200R-S1 is designed for slot-style server power integration. It is suitable for platforms where the PSU is inserted into a defined power slot instead of a standard CRPS bay.

05

I²C Communication Support

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

06

Built for High-Power Server Deployment

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