Industrial DL 7030IE Industrial Control Transformer

Description:

The TMS Prim DL 7030IE Control Transformer is a 1 VA encapsulated step-down transformer designed to convert a 277 VAC primary input to a 120 VAC secondary output for low-power industrial control circuits. Commonly installed in electrical control panels, HVAC equipment, lighting control systems, and automation cabinets where isolated control voltage is required for relays, timers, and electronic controls. Maintenance personnel, panel builders, OEMs, and electrical contractors use this transformer for new installations, equipment repairs, retrofits, and replacement of failed control power transformers.

Applications:

The TMS Prim DL 7030IE Control Transformer is used to provide isolated 120 VAC control power from a 277 VAC supply in industrial and commercial electrical systems. Its compact 1 VA design makes it suitable for energizing low-power control devices, pilot circuits, timers, relays, and monitoring equipment used in automation, lighting, and building control applications.
