The YH5301-1EA57R is a 300 W industrial-grade power supply built in a 1U redundant configuration for mission-critical systems. It integrates two hot-swappable modules in an N+1 arrangement, so power output continues uninterrupted even if one module is removed or fails. With 80 PLUS Silver efficiency certification, it operates efficiently to reduce waste heat and energy costs. The unit accepts a full 90–264 V AC input range at 47–63 Hz, supporting global mains voltages without manual switching. It delivers standard ATX DC rails including +5 V, +3.3 V, +12 V, -12 V, and +5 V Standby. The design requires no minimum load on any output, helping maintain stable operation even at idle or very low loads. PMBus 1.2 support enables digital monitoring and control for proactive system management. Designed for industrial PC, storage server, embedded server, and networking applications, it combines high availability, active power factor correction, and broad regulatory compliance for dependable 24/7 operation.

FAQs
for YH5301-1EA57R 300W 1U Redundant Industrial AC/DC IPC Power Supply
N+1 redundancy means the unit contains two power modules, but only one is required to support the full 300 W load. The second module acts as a live backup, so if one module fails or is removed, the remaining module continues powering the system without interruption. This design improves availability and allows maintenance without shutting the system down.
The 80 PLUS Silver rating indicates high conversion efficiency, reaching around 89% at full load. Higher efficiency means less wasted energy, lower heat output, reduced cooling burden in compact 1U systems, and improved long-term reliability for both the PSU and nearby components.
Yes. The power supply supports a full-range 90–264 V AC input at 47–63 Hz, so it can operate on North American 115 V mains, European and Asian 230 V mains, and other common supply ranges without manual switching.
PMBus 1.2 is a digital power-management protocol based on SMBus/I²C. On this PSU, it can be used by a compatible motherboard or controller to monitor values such as voltage, current, temperature, and overall power-supply status. It supports proactive maintenance by helping system software detect faults, warnings, or abnormal operating conditions.
No. The YH5301-1EA57R is designed with no minimum load requirement, so its outputs remain regulated even when rails are lightly loaded or completely unloaded. This is especially useful in modern industrial and server systems with variable power consumption.
Yes. The included YM-2301EAR modules are hot-swappable, allowing a faulty module to be removed and replaced while the other module continues supplying power. This minimizes downtime and supports continuous operation in critical systems.
