The WP Series DC/DC converters offer two unique features. Amp-Reg is an
innovative design that permits parallelling of outputs. The ultra wide input
voltage range of 9VDC to 36VDC or 20VDC to 72VDC covers the standard
inputs of 12VDC, 15VDC, 18VDC, 24VDC, 28VDC, 36VDC, and 48VDC with two
models. The WP Series DC/DC converters employ 100kHz switching regulator
techniques to provide operating efficiencies as high as 85% at full load. Short
circuit current limiting and overvoltage protection are standard on all models.
The output of all WP Series DC/DC converters may be remotely controlled with
a logic compatible signal or relay contact closure. When turned off, the idle
current is only 5mA. All models have 500VDC minimum isolation and no
derating is required.
SPECIFICATION All specifications are typical at nominal input, full load at 25°C unless otherwise stated
