Product Description

The Sanzo Power TX-CL Series 300 VA industrial control transformer delivers a low, safe, isolated control voltage for machine-tool and automation circuits. Rated 300 VA with a 277V primary and 120V secondary, it steps line voltage down to power contactors, relays, solenoids, timers, pilot devices and PLC circuits.

The EI core and copper windings are built for the heavy momentary inrush that electromagnetic coils draw at pick-up while holding secondary voltage stable—regulation exceeds NEMA recommendations. A 130°C Class B insulation system and 80°C rise support continuous duty in hot panels and enclosures. The secondary is fully isolated from the primary line for a separate, safe control circuit.

This model is supplied with box-lug terminals (ring-terminal screw clamps with isolation barriers), mounted on a 35 mm DIN-rail clip. Single 277V primary winding. Finger-safe box lugs and finger-safe terminal blocks are available on request, as are integral primary or secondary fuse blocks and custom voltage combinations.

Standard lead time: 7-8 weeks. Made to order. Contact Sanzo Power for a quote.
