Embedded DC/DC converter TH20F1210C8E-WT

for EV chargervariable-outputfan cooled

Product Overview
The TH20F1210C8E-WT is a 20 kW EV DC charging power module designed for integration in charging piles and stations. It supports wide AC input and a broad DC output range with a constant-power band for efficient fast charging. The module uses intelligent fan cooling and communicates with the host controller via CAN for configuration and control.
