The UR-RHV is a Multilin General Electric power supply module and is compatible with the Multilin series of universal relays. For example, the Multilin universal relays include the D30 line distance relay, C30 I/O logic controller, and the T60 transformer management relay. The universal relays have slots to accept a Multilin power supply to receive power to the universal relay similar to the UR-RHV power supply module for example. Over the years, GE Multilin has come out with three types of power supply modules, the UR-1H series, the UR-RH generation, and most recently the UR-SH. The UR system of universal relays is compatible with the updated power supply modules as well even if it was first purchased with a power supply of the original generation. Similarly some universal Multilin relays require two power supply modules. In this event, the recommendation is that the generations remain the same for the two power supply modules included with the universal relay. 

The power rating for the UR-RHV Multilin power RH generation is 125 to 250 V at 35W and 100 to 240 VAC at 35 VA.
