通用电气公司的UR-RHH是一种电源模块，设计用于安装在通用继电器系列中。

GE URRHH该模块可订购两种电压范围，可包括或不包括冗余电源选项。低量程(LO)在24至48 V标称电压下工作(仅DC)，而高量程(HI)在125至250 V标称电压下工作(DC和交流)。电源模块能够向继电器供电，也能够向干触点输入连接供电。该电源模块的内部保险丝额定值为4A / 250 V

GE URRHH继电器的自测元件可以自动评估电源模块的健康状况。用于确保设备完整性的主要和次要测试可以评估正确的硬件功能，并在出现严重故障时切断电源模块的电源。

如果测试检测到硬件问题或严重故障，系统可以通过位于所有UR设备面板上的led向附近的用户指示这一情况。与电源直接相关的面板led包括持续打开、打开/关闭循环和关闭。

The General Electric Company's UR-RHH is a power module designed to be installed in the general purpose relay family.

The GE URRHH module can be ordered in two voltage ranges, with or without redundant power options. Low range (LO) operates at nominal voltages of 24 to 48 V (DC only), while high range (HI) operates at nominal voltages of 125 to 250 V (DC and AC). The power module can supply power to the relay and the dry contact input connection. The power module has an internal fuse rating of 4A / 250 V

The GE URRHH relay's self-testing element automatically assesses the health of the power module. The primary and secondary tests used to ensure the integrity of the device can assess proper hardware functionality and cut off power to the PSU in the event of a serious failure.

If the test detects a hardware problem or serious failure, the system can indicate this to nearby users via leds located on the panels of all UR devices. Panel leds directly related to power supply include continuously on, on/off cycle, and off.
