The HK2200R-S1 provides 2200W output for server systems that require a high-power slot-style power module with multiple regulated output rails. It is suitable for server platforms where the PSU needs to support dual 12V rails together with auxiliary 5V, 3.3V, 5VSB, and -12V outputs.

2200W Slot-Style Power Capacity

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.

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.

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.

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.

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.

POWER DESIGN

Reliability notes for continuous operation.

The HK2200R-S1 focuses on high-power multi-output server power delivery. Instead of using only one main 12V rail, it provides dual 12V rails plus several auxiliary outputs, making it suitable for server systems that need direct power support for different boards, control circuits, backplanes, and standby functions.

2200W rated output supports high-power server boards, backplanes, storage controllers, cooling fans, and auxiliary system circuits.
The main 12V outputs include +12V1 145A and +12V2 108A, supporting stronger rail distribution for server load groups.
Auxiliary outputs include +5V 50A, +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.
I²C communication supports PSU status communication with compatible server platforms.
Protection functions include output overvoltage, output undervoltage, output overcurrent, output short circuit, and overtemperature protection.
EMI performance is listed as EN55022 Class A, and forced air cooling helps maintain stable thermal operation.

INSTALLATION

Installation and operating guidance.

The HK2200R-S1 uses an IP20 protection rating and is mainly designed for server applications. Because this model provides multiple output rails, system designers should evaluate each rail separately instead of judging suitability only by total rated power.

Installation / Operation Item	Guidance
Input Matching	Confirm the system input supply matches the required 11.4–12.6Vdc input range
Rail Load Planning	Match server board and backplane requirements with +12V1, +12V2, +5V, +3.3V, 5VSB, and -12V outputs
Chassis Fitment	Confirm the 265 × 77 × 84 mm external dimensions before slot-style integration
Communication Setup	Use I²C communication only with compatible system monitoring and control designs
Thermal Clearance	Keep intake and exhaust channels open to support forced air cooling under high-load operation
Operating Environment	Keep air temperature within 0–55°C and relative humidity within 5%–95%, with no condensation
Storage Condition	For storage and transportation, keep within -40°C to 70°C and 5%–100% RH
Protection Review	Confirm system-level fault handling for overvoltage, undervoltage, overcurrent, short circuit, and overtemperature events
