The GE URRHV is a high-performance, second-generation power supply module engineered specifically for the Multilin Universal Relay (UR) series. This high-voltage (HV) variant is designed to sustain the rigorous demands of utility and industrial protection systems. The “V” in the model designation signifies its specific engineering for vertical mounting configurations, ensuring that thermal dissipation and internal component orientation are optimized for vertically aligned relay chassis.
Physical Design and Mechanical Integration
The compact footprint of the URRHV allows for high-density panel integration. Despite its robust power delivery, it maintains a small form factor, making it suitable for modern, space-constrained switchgear. It features a secure slide-in mechanical interface that ensures reliable electrical contact with the relay backplane even in high-vibration environments.
