Isolated DC/DC Converters operate over -60 to +125°C range.

Press Release Summary:

Available in metal cases with 0.5 in. profile and mounting flanges, TEC-100 and TEC-200 Series provide 100 and 200 W continuous power for heavy industrial and harsh environment applications. Series provides both 2:1 and 4:1 input ranges of 9–18, 9–36, 18–36, 18–75, and 36–75 Vdc; 5 single-output models offer voltages from 5–28 Vdc. Exhibiting up to 93% efficiency, converters are sealed in heat-conducting potting material and can be connected in parallel or series configurations.

Original Press Release:

New DC-DC Converter's Ultra-Wide Temperature Range Designed for Compact Industrial Applications

Hopkinton, MA — Schaefer, Inc. is proud to announce 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°C to +125°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 28VDC. 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  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.

Detailed product specifications can be viewed at TEC-100 and TEC-200.
