Overview
The ACME T-2-53007-S transformer is a general-purpose, dry-type isolation transformer designed for single-phase industrial control and voltage conversion applications. With a 0.25 kVA power rating, dual primary voltage input (240/480V), and secondary output of 120/240V, this compact transformer operates at both 50 and 60 Hz. The Type 2 indoor enclosure makes it suitable for equipment rooms, control panels, and general industrial environments.
Key Features
- Single-phase isolation design for complete galvanic separation between primary and secondary circuits
- Flexible primary voltage input: connects at 240V or 480V without rewiring
- Dual secondary output (120/240V) supports multiple load configurations
- 0.25 kVA (250 VA) capacity suitable for control circuits, signal conditioning, and low-load applications
- Dry-type, encapsulated construction with no oil or liquid cooling required
- Rated for 50/60 Hz operation for global deployment
- Type 2 NEMA indoor enclosure protects internal components
