544-W DC/DC power module provides 95% efficiency for wireless networks

October 25, 2013 // By Paul Buckley
GE’s Critical Power business has introduced an isolated DC/DC power module that delivers 544 W with 95%

A new addition to GE’s ORCA series of DC/DC converters, the JRCK017A0S32R0 provides up to 17A of DC output current at a nominal output voltage of 32 VDC. The Distributed-power Open Standards Alliance (DOSA)-compliant, half-brick form factor is aimed at high-voltage, high-power applications such as wireless and switch networks.

The new module also offers Tunable Loop, an optional feature that enables a user to optimise the dynamic response of the converter to match the load, with reduced output capacitance. This feature enables original equipment manufacturers to reduce board space and overall product cost.

The JRCK017A0S32R0 DC/DC converters are claiming best-in-class efficiency and density and are capable of delivering 544W in an industry-standard DOSA-compliant,  half-brick footprint.

The devices are available in threaded or non-threaded insert standoff versions enabling easy mounting and the addition of a heat sink for high-temperature applications.  The DC/DC module can be used to power RF power amplifiers or other applications requiring 32V.  The device also supports repetitive loads (AC+DC) up to 2 kHz and has an output voltage adjustment trim of 16V to 35.2V.

Pricing for the JRCK017A0S32R0 DC/DC power module begins at $54 (1000 pa order rate).
