- Partner
- FSP Protek
Designed for server, datacentre, communication, and industrial systems, the FSP2000-20HM delivers up to 2000 W of stable 12 V DC output in a compact CRPS 1U form factor. Its hot-swap architecture supports N+1 redundancy, allowing module replacement without shutting systems down. With 80 PLUS Titanium efficiency, it helps reduce energy loss, heat generation, and cooling demand in high-density deployments. The module supports a wide 90–264 V AC input range and an optional 180–310 V DC input range for flexible infrastructure integration. PMBus 1.2 communication enables real-time monitoring, reporting, and control through system management platforms. Additional strengths include configurable airflow, firmware customisation, comprehensive protection circuits, cold redundancy support, and compliance with international safety and EMC requirements.
The FSP2000-20HM power supply module is engineered for demanding environments where uptime, efficiency, and serviceability are critical. Built around the Common Redundant Power Supply (CRPS) standard, it is suited for datacentre servers, high-performance workstations, communication platforms, and industrial automation systems.
Its compact hot-swap design simplifies maintenance while supporting resilient power architectures for systems that cannot tolerate interruption.

FAQs
for FSP2000-20HM 2000W CRPS Redundant Hot-Swap AC/DC Power Supply Module
CRPS stands for Common Redundant Power Supply. It defines a standardised server power module format, helping ensure compatibility with many server and storage chassis that support CRPS-based power architectures.
Yes. The module is designed for hot-swap operation, which means it can be replaced while the system remains powered on. In N+1 configurations, the remaining power supplies continue supporting the load during replacement.
The unit is 80 PLUS Titanium certified and reaches approximately 95–96% efficiency around typical operating loads, helping reduce wasted energy and cooling demand in high-density installations.
Yes. It supports a wide 90–264 V AC input range and can also be configured for 180–310 V DC input, making it suitable for a variety of power infrastructures.
The module includes a PMBus 1.2 interface for digital power management. This allows compatible system controllers to monitor voltage, current, temperature, status, and fault conditions in real time.
The FSP2000-20HM includes over-current protection, over-voltage protection, over-temperature protection, and short-circuit protection. These features help protect both the PSU and connected equipment during abnormal operating conditions.
