The concept of laboratory DC voltage sources, which has been proven over the years, is designed to power DC electrical devices in industry and education. The robust metal construction, linear regulation and constancy of parameters determine them for use even in the most demanding tasks.
Characteristics of laboratory DC voltage sources
Control of individual outputs with separate buttons.
LED signaling of switching on outputs and functional states.
Intermittent warning sound signaling of current limitation.
Optical signaling of current limitation with a decimal point on the ammeter display.
Large, readable, red LED displays.
“Coarse” and “fine” voltage adjustment using a potentiometer.
Automatic cooling fan.
A transformer designed for continuous power supply to the load.

Soft-start
The outputs of the sources are activated after the laboratory source is switched on and after the test has been performed. The connected devices are thus protected against possible voltage peaks arising during start-up.
