Description
The 8.5 Watt Triple Output DC/DC converters are ideal for
wide (4:1) input range applications. These units are particularly
well suited for solar powered RTUs and instruments.
They are designed with a high accuracy feedback control
circuit and coupled inductor magnetics. Each converter has
both a logic shut down pin and thermal overload protection
circuitry. All outputs and the power switch are overvoltage
protected.
These converters are encased in a six-sided, completely
shielded copper case. The UW Triple Series is covered under
the CALEX 5 Year Warranty.
