It can also be used as a simple generic power supply delivering +5 V, 1 A (from the shared +12 V unregulated supply via a 7805 type regulator) and ±15 V, 400 mA with current limiting (the latter using the mainframe's pass transistors). For this mode, the rotary switch must be in position 3 and the toggle switch set to DC. | It can also be used as a simple generic power supply delivering +5 V, 1 A (from the shared +12 V unregulated supply via a 7805 type regulator) and ±15 V, 400 mA with current limiting (the latter using the mainframe's pass transistors).
