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. Technical parameters Fixed voltage 5 V Fixed current 3 A Ripple typical < 2mV Ripple maximum 10 mV Voltage stability for mains change +6/-10% - approx. 0,05% Current stability for mains change +6/-10% - approx. 0,05% Type of measuring devices - 888 LED Number of measuring devices 4 Measurement accuracy class 2 Connection of adjustable sources into a symmetrical source - YES Electronic radiator thermostat with fan - YES Output state memory before shutdown YES Colour black Dimensions in mm (h, w, d – approx.) - 172 x 244 x 282 Weight approx. 10 kg Warranty - 24 months 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.
