The UMG104 is intended to be used for the measurement and calculation of electrical variables such as voltage, current, energy, work, harmonic components, etc. in building installations, at distribution boards, circuitbreakers and busbar trunking systems. Measuring-circuit voltages and currents must originate from the same system. The UMG104 is permanently installed in control cabinets or small distribution boards. It can be installed in any position. The measurement results can be displayed, stored and read out via serial interfaces and further processed. The voltage measurement inputs are designed for measurements in low-voltage systems in which rated voltages up to 300 V conductor to earth and surge voltages of overvoltage category III can occur. The current measurement inputs of the UMG104 are connected via external ../1A or ../5A current transformers. Mains failure detection The mains failure detection takes place via the voltage measurement inputs. The selection of voltage measurement inputs can be configured using the GridVis software. Mains failure stored energy time The UMG104 bridges the following mains failures at the auxiliary voltage input: Mains voltage Stored energy time 230V AC max 80ms
