DPS-1300AB-21 Key Product Features

1. 80 PLUS Platinum Efficiency

The DPS-1300AB-21 meets the 80 PLUS Platinum efficiency certification standard, achieving over 94% efficiency at 50% load, effectively reducing power loss and operational electricity costs in data centers.

2. N+1 Redundancy Capability

The modules support an N+1 redundancy configuration, enabling hot-swap maintenance and uninterrupted power supply within server power systems. If a power module fails, the remaining modules automatically take over the load, ensuring continuous system operation.

3. PMBus 1.2 Digital Communication

Built-in support for the PMBus 1.2 protocol enables real-time monitoring and remote management of operating parameters such as voltage, current, temperature, and power, facilitating precise power status monitoring and fault early warning for data center operations and maintenance teams.

4. Multiple Protection Mechanisms

The module integrates multiple fault protection features, including overvoltage protection (OVP), overcurrent protection (OCP), and overtemperature protection (OTP). Combined with a built-in speed-adjustable cooling fan, these ensure stable operation under varying loads and ambient temperatures.

5. Wide Input Voltage Range and PFC

Supports a full-range AC input of 90–264 VAC and features built-in active power factor correction (PFC) with a power factor greater than 0.98, making it adaptable to various global power grid environments and reducing harmonic distortion in the grid.

Typical Application Scenarios

As a standard CRPS front-end power module, the DPS-1300AB-21 is widely used in the following scenarios:

Enterprise-Class Servers and Data Centers: Provides highly reliable, redundant power supply for rack-mounted servers; supports N+1 configurations to meet high-availability requirements

Network Switches and Routers: Delivers a stable 12V DC power supply for core telecommunications network equipment

Storage Systems: Provides high-efficiency power supply for storage devices such as disk arrays and NAS

Workstations and High-Performance Computing: Delivers high-power 12V power supply for GPU workstations, AI inference servers, and similar applications

Telecommunications Equipment: Suitable for 12V distributed power architectures in carrier-grade data center equipment
