The UMG103 is intended to be used for the measurement and calculation of electrical variables such as voltage, current, power, work, harmonic components, etc. in building installations, at distribution boards, circuit-breakers and busbar trunking systems.
It can be installed in any position. The measurement results can be read out via the RS485 interface. The UMG103 draws its power supply voltage from the measuring-circuit voltage. The UMG103 is designed for operation in low-voltage distribution systems, in which overvoltage category III (300 V) impulse voltages can occur. The UMG103 can measure L-N voltages of up to 240 V and short-term overvoltages up to 300 Vrms.
