DC/DC Converters TEN 25 Series, 25/30 Watt Features ◆ Wide 2:1 Input Range ◆ Very high Efficiency up to 89% ◆ Extended Operating Temperature ◆ Range –40°C to +85°C ◆ Adjustable Output Voltage ◆ Remote On/Off ◆ Continuous Short Circuit Protection ◆ Over Voltage Protection ◆ I/O-Isolation 1500 VDC ◆ Input Filter meets EN 55022, Class A and FCC, Level A without external Components ◆ 3 Year Product Warranty The TEN 25 series is a range of isolated DC/DC converters with high power density in a 51x41x9.5mm shielded metal case. All 18 models have a wide 2:1 input voltage range. The very high efficiency allows a safe operating temperature range of –40°C to +85°C. Other features are internal EMI-filter to meet EN55022, class A and remote On/Off. Typical applications for these converter modules are industrial electronics, communication systems, battery operated equipment and distributed power systems.
