The efficiency is test by nominal input and max. full load @25°C.
The capacitive load is test by minimum input and constant resistive load.
All specifications valid at nominal input voltage, full load and 25˚C after warm-up time unless otherwise stated.

CTC is the professional and one among world’s leading manufacturers of DC-DC/ AC-DC converters.
The products were used in Computers, Industrial controls, Medical equipment, Transportation, EV, ECO-power, Aero-space application and communication.
