Lab power supply HG3005
A very accurate power supply with protection against high temperature, short circuit, overload and damage. The output voltage and current are controlled steplessly with coarse and fine knobs - separately for the output current and voltage. The device operates in „constant current” (CC) and „constant voltage” (CV) modes.
