Dallas, Tex. — GE’s Critical Power business has expanded its Orca*-series of isolated, board-mounted power amplifier modules with the new ERCW003A6R 100-watt, one-eighth brick DC-DC converters. The high-efficiency converters provide a typical efficiency of 93 percent at full load and a nominal output voltage of 28 volts. They provide high-voltage and high-power applications with up to 3.6 amperes DC output current at a nominal output voltage of 28 volts.
The output range of the DC-DC converters can be trimmed from 15 volts to 35.2 volts, allowing the device to be used in a broad range of applications. In addition, with a maximum output ripple of 40 millivolts root mean square, the ERCW003A6R helps reduce the need for external filtering capacitors and cuts overall system cost, said GE. These converters can be used in RF power amplifiers, wireless networks, and switching networks.
The ECRW003A6R’s open-frame construction and heat-plated design offer through-hole packaging that enables designers to develop cost, space and energy-efficient end solutions, said GE. The threaded through holes make the DC-DC converters easy to mount or for a heat sink to be added for high-temperature applications. The output is fully isolated from the input, enabling versatile polarity configurations and grounding connections.
The DC-DC converters are DOSA (Distributed-power Open Standards Alliance) compliant. Other features include a wide input voltage (Vin) range of 36-75 Vin, 2,250-volt DC input to output isolation, and support for repetitive loads (AC+DC) up to 2 kilohertz. The industry-standard footprint measures 58.4mm x 23.0mm x 8.8mm (2.3” x 0.9” x 0.35”).
Availability: The ERCW003A6R ORCA-series DC-DC converters are now available in volume quantities.
Pricing: Starts at $24.70 per module at an annual volume of 1,000 units.
