New low-profile AC/DC supplies perform in harsh environmental conditions

Schaefer has unveiled low-profile TERa Series of advanced thermal technology AC/DC power supplies. The new family offers three output power classes of 700, 1200 and 2000W. They are 'uniquely' sealed in a heat conducting potting material. Featuring an ultra-wide temperature range of -50C to +85C the units target space critical projects that demand reliable and shock-resistant performance in the harshest operating conditions. All models are designed for easy-to-connect parallel / series operation if higher power or redundancy is needed. Other features include high power density, power factor correction (PFC), 100-242VAC universal inputs, galvanic isolation, high efficiency, full complement of protections, single or multi-output operation, output voltage adjustment and compliance to EN55022 Class A (Class B with filter). Additionally, each unit goes also through comprehensive temperature cycling and burn-in. Optional cooper case and terminal block connections are available. These characteristic combined with COTS pricing makes them ideal for a wide range of applications including but not limited to industrial automation, communications, rail/transit, oil/gas, utility, alternative energy and COTS defence systems, says the company.
