The Atman CTR M/S 250 VA is a single-phase isolation transformer housed in a closed enclosure for continuous operation. With a 230V primary and 230V secondary winding, it delivers 3750V AC isolation voltage, making it appropriate for installations that need galvanic separation without altering the supply voltage level.

The transformer is built to Class I protection standards with insulation classes B, F, and H and an IP20 protection degree. It operates in air under normal ambient temperature conditions.

Key Features
