Description
PRODUCT OVERVIEW
GE WESDAC D20ME is a dedicated high-power power supply module belonging to GE Multilin UR universal relay series, specially configured to supply stable working power for UR series comprehensive protection relays and their dry contact input loops. The module accepts wide-range high-voltage DC input of 125V~250VDC, converts it into multiple groups of stable low-voltage working power inside the relay body, supporting continuous stable power supply for relay measurement acquisition, logic operation, communication circuit and fault trip output loop.Built-in overvoltage, overcurrent, short-circuit and reverse connection multi-level protection circuits, with 20ms power hold-up capability under full load, which can avoid relay abnormal reset or protection misoperation caused by instantaneous power grid voltage drop. Standard 19-inch rack/DIN rail dual installation design, matched with all UR series protection devices, configured and diagnosed via EnerVista UR configuration software, widely used in power substation line protection, transformer protection, generator unit protection, industrial high-voltage motor protection system maintenance and spare parts replacement projects.
