DC-POWERCONVERSION
ISOLATED DC/DC CONVERTERS
DC DC converters are designed to increase, or decrease, the DC voltage that is input to the unit.
The Unitek DC-Powerconversion products offers DC converters that will convert source DC into a
variety of output voltages at power levels to suit your requirements.
The IDC-series is a complete line of high efficiency 100, 200 or 360 Watt isolated DC-DC converters
suit for applications requiring galvanic isolation between the input and the output. The isolated converters
provides a highly regulated output DC voltage of 12.5, 24.5 or even 48 Vdc and rated output of 8, 15
or 30 Amp (12 Vdc models) 4, 8, 15 Amp (24 Vdc models) and 4, 7.5 Amp (48 Vdc models)

DC-POWERCONVERSION
NON ISOLATED CONVERTERS
A complete line of high quality
DC/DC converters in a compact housing.
This series is eminently suitable for
applications requiring stability, a modest
development of heat and above all a low
energy consumption. These products
are also distinguished by high efficiency,
together with absolute safety. An inferor
supply can cause irrepairable damage
to your 12 Volt system, but using an

Unitek voltage converter will prevent
problems of that type. Next to the standard
(non isolated) 24/12V converters, a wide
range of other models is available.
The SDC 20 , SDC 30 and SDC 60 can
also be used as a 13.8Vdc batterycharger,
to charge from a 24V system a 12V starter
or accessory battery.
