3kW Power supplies provide wide output adjustability
ABSOPULSE ELECTRONICS LPS 3K ac/dc power supply series with PFC input was designed specifically for applications that require wide output adjustability. This heavy-duty, industrial grade series is available in bench-top and 19” rack-mount format and is suitable for product testing and similar purposes in engineering labs or in the field. A broad range of models are available, with lead times of only a few weeks. Units are built with internal modules that are typically available from stock for the output ranges 14-37V (24V) at 80A, 28-74V (48V) at 40A or 60-160V (125V) at 18A. Output voltage and current are displayed on analog meters on the front-panel of the unit. Output voltage adjustments are made via a potentiometer knob which is located just below the meters. Electronic adjustment by analog control voltage (0 – 10V or similar) is also available. The isolated, floating output can be grounded to either terminal so the unit can be used in either positive or negative grounded systems or left floating.
