Ultra-Wide Temperature DC-DCs for Compact Industrial Applications

Schaefer, Inc. has announced the TEC-100 and TEC-200 Series of isolated dc-dc converters that provide 100W and 200W of continuous power that feature high efficiency (up to 93%) and -60 to +125 degrees C operating temperature range. These units are especially designed for heavy industrial applications and harshest environment conditions. The TEC Series provides both 2:1 and 4:1 wide dc input ranges of 9-18Vdc, 9-36Vdc, 18-36Vdc, 18-75Vdc, and 36-75Vdc.

Five single-output models offer output voltages ranging from 5- to 28-Vdc. All modules also offer comprehensive protection circuitry including over-current, over-temperature and short-circuit protection. They can be enabled/disabled remotely and be easily connected in a parallel or series configurations. EMC filtering meets EN55022 Class A and EN 55022, Class Ð’ with an additional Schaefer filter. Worldwide safety approvals are to IEC/EN 60950 standards.

The TEC Series converters are sealed in an efficient, heat-conducting potting material and they undergo special thermal and limit tests, including temperature cycling and burn-in. With the absence of opto-couplers and electrolytic capacitors in the converter’s circuit, a greater MTBF is ensured in high-temp applications. The low-profile 0.5” converters are available in metal cases with mounting flanges.
