The ULT Series isolated DC/DC converter represents the next generation converters in a 1/32 brick package. This converter is the “industry standard” 1/32 brick form factor (0.92" x 0.75" x 0.35"). The product fully complies with RoHS-6 directive.

The thirty-second brick is offered as an open frame module; mounting options include through hole or surface mount (SMT) pin outs. Typical applications include Optical Networking Equipment, Wireless Base Station applications, Microwave Radio communications, and Telecom and Data Equipment applications.

Modules will supply an output power of 22.5W min. and 30W max. over the input range of 36-75V. The ULT Series also provides a cost effective approach to highly efficient systems requiring 12V, 5V, and 3.3V voltages, eliminating the requirement for a “Bus Converter” and multiple PoL converters. The ULT family provides basic insulation with 1500Vdc isolation meeting the requirements of EN60950. The ULT series modules are DOSA compatible industry standard 1/32 brick.
