Description

Through the use of state of the art surface mount technology the 2482 series is able to offer considerable advantages over equivalent products both electrically and mechanically. These modules are designed to operate from dc supply of either +/-12V or 24V, and provide a closely controlled high voltage output. The use of high stability components in the feedback system, ensures a low temperature coefficient and good long and short term drift.

The modules are coated and housed within a metal case, providing excellent screening. The output voltage may be controlled from zero to maximum output by either an external control voltage or by a user accessible multi-turn potentiometer. These units will deliver up to 4W of regulated power at their maximum voltage settings. For ease of operation a precision internal reference is provided (9.00V) for use with an external control potentiometer.
