We build mains voltage stabilisers with rated outputs of up to 800 kVA to customer-specific requirements in one-phase and three-phase versions with common or separate regulation of the phases. They compensate voltage fluctuations of ± 25% and have an output tolerance of ± 1.5%.
The NRD1 transforming voltage stabiliser from ISMET guarantees a constant voltage even with sensitive mains conditions. It has an output of 250 kVA, a permissible input tolerance of ± 20% and regulates all three phases together. The mains voltage stabiliser comprises a fixed transformer, a three-phase column and a neutral point transformer. The system is installed in a switch cabinet with protection rating IP54 and stabilises the output voltage to ± 1.5%.
