TXDW / TEP-M-X Small Power Supply Module

Product Details

The TEP-M-X-series small scale high frequency switching power supply module is designed for small scale DC systems (≤ 65AH in DC220; ≤100AH in DC110) and high voltage DC distribution power supply systems used in switching substations and main stations. The module is of small size and low cost, reliable and easy to install. It is available wall-mounted, cabinet and rack unit style as TXDW small DC power supply systems or as accessory unit.

Product features
