Focusing on a wide range of applications, the WL7 series switching power supplies deliver up to 450W and constant voltage/current crossover. Models with wide output voltage ranges are adjustable down to 0V and both voltage and current are programmable with 0 to 10V control-voltage inputs. The units include voltage- and current-monitor outputs and an inhibit terminal on the pluggable connectors that enable quick wiring of the control and input leads. Provisions for N+1 redundancy and paralleling for higher current are optional. Other features include extruded aluminum cases, universal inputs, PFC, soft-start operation, Vout okay indicators, and no-load operation. Price for models with nominal outputs from 3.3V/45.4A to 48V/9.4A is $590 and wide-adjust models with ranges from 0 to 5V/44A to 0 to 50V/9A are $615. ACOPIAN, Easton, PA. (800) 523-9478.
