Detail
Conventional isolation transformers can be tailored to your voltage, KVA, and insulation needs, fitting your setup for precise, efficient performance. Epoxy cast transformers provide robust operation with primary voltages from 120 V to 240 V, isolation up to 50 kV DC, and VA ratings from 100 VA to 1000 VA. Customisable configurations, including charging reactors, pulse forming networks, rectifier and trigger transformers, chokes, capacitor charging transformers, and pulsed modulators, support your systems in achieving safe, stable, and efficient operation.
