The low-price compact DC power supply / supplies of the TOE 8721 series are suitable for general laboratory purposes as well as for loads with a pulsed current consumption.

The TOE 8721-2, 8721-3 and 8721-4 versions additionally enable a current consumption increased by up to 50 % for approx. 15 minutes.

As a result of the delayed current limiting function, current pulses can be drawn from these models up to several times the rated current for several ms.

The output voltage and output current are indicated on highly precise 3½-digit LCDs. The output voltage is set using a high-resolution ten-turn potentiometer.

The practice-oriented dual-output power supplies of the TOE 8722 series have output powers of 72 W, the outputs are independent of one another and the voltages are adjusted using precision ten-turn potentiometers and the currents using stable single-turn potentiometers. Two selectable 3½-digit LCDs indicate the output values.
