This rugged, industrial quality, ac/dc power supply series with PFC input is specifically designed for applications that require wide output
adjustability. They are suitable for product testing and similar purposes in engineering labs or in the field. A variety of models are
available which can readily be adapted to customer requirements with lead times of only a few weeks. The units are built with fieldproven internal modules which are typically available from stock for the output ranges of 14-37V (24V), 28-74V (48V) or 60-160V
(125V). The output voltage adjustment potentiometer knob is located on front panel of the unit. Electronic adjustment by analog
control voltage (0 – 10V or similar) is also available. Other output voltages and adjustment ranges are available on request. Output
voltage and current are displayed on analog meters on the front panel of the unit. Heavy-duty terminals for the output are also located
on the front-panel. The AC-input is equipped with a breaker, which is also used as an ON/OFF switch. Cooling is by high quality internal
fans, which provide sufficient airflow for operation at the specified temperature range without de-rating. The units are available in
bench-top and 19” rack-mount format. Full electronic protection, low component count, large design headroom and the use of
components with established reliability result in a high MTBF. The unit is manufactured at our plant under strict quality control.
