Switching Power Supplies (for OEMs)

The STR-300 bench supply is designed for general laboratory use and is equipped with front-panel mounted voltage and current controls, a combination volt/ammeter, and output binding posts. Output voltage and curent are continuously variable, via coarse and fine conttrols from 0 to 15% above 10 VDC. A switch selects either output voltage or curent for display on the panel meter.
Load connections are made via three binding posts. Either the + or the - post may be grounded through an adjacent GND terminal or the supply may be operated floating at up to 300 volts above ground.
This supply can also be operated as a constant current source with 500 µA load regulation.
