Atman TRF 1000 VA 230/230V Three-Phase Isolation Transformer – Open-Type & Continuous Duty

The Atman TRF 1000 VA is a three-phase open-type isolation transformer with a 230V/230V ratio. It is built for continuous duty in air under normal ambient conditions, making it appropriate for industrial and technical installations that require galvanic separation between three-phase circuits.

With an isolation voltage of 3750V AC and insulation classes B, F, and H, the TRF 1000 VA meets demanding electrical isolation requirements. The Class I safety rating and compact 180×160×110mm form factor support integration into panel-mounted and bench-mounted applications.
