Digital power module TH20F10025C7E-WT

for charging electric vehiclesACDC

Product Introduction
TH20F10025C7E-WT is an AC/DC charging module designed for EV charging stations. It delivers a rated output power of 20 kW, an ultra-wide constant-power output range (300–1000 VDC), and supports three-phase AC input from 274 Vac to 487 Vac. The module uses intelligent air-cooled thermal management and interfaces with the main controller via CAN bus for parameter configuration and status control.
