The 6215A Power Supply is a compact bench power supply designed for general lab use. It is equipped with front-panel coarse and fine voltage controls, a combination volt/ammeter that is switch selected, and output binding posts. With an output of 0 to 25 VDC at a current level of 0.4 amps it has a load effect of 4 mV and a source effect of 4 mV. This power supply features constant voltage/current limiting which supplies a short-circuit protection by a fixed current limiting circuit which is activated at approximately 120% of rated load current. Input requirements are 115 VAC ? 10%, 48-440 Hz.
