A small motor which operates from 1.5 to 4.5 volts DC with small pulley.

The DC Regulated Power Supply is an easy to use, low ripple high regulation precision instrument. Its unique feature is overload protection which makes it a safe power source for testing of electronic equipment.

Both voltage and current are precisely regulated with low output ripple. The power supply can be operated in either constant voltage or constant current mode and is protected aLIinst overload or short circuit by means of automatic cross-over characteristics from C.V. to C.C.

The output voltage and currents can be read on a meter. A switch is provided to select the LOW or HIGH' range of current. Maximum voltage is 30 volts.
