Specifications:
The general specifications for a Rex Power Magnetics 1 kVA (1000 VA) 3-Phase Transformer span several potential configurations, as Rex manufactures 1 kVA units under their specialized Industrial Control or Custom Low-Voltage categories.
Because exact specifications depend on your primary and secondary voltage configurations, a breakdown of the standard engineering data for Rex units at this capacity is detailed below:
- Capacity: 1 kVA (1,000 Volt-Amps)
- Phase: 3-Phase (3Ph)
- Frequency: 60 Hz standard (50/60 Hz optional)
- Common Voltages:
-
- Primary (Input): Commonly 208V, 480V, 600V, or 690V.
- Secondary (Output): Commonly 120V, 208Y/120V, 230V, or 480Y/277V.
- Winding Material: Copper (Standard for industrial control and low-kVA compact frames).
- Insulation Class: Typically 130°C or 180°C class for control-style configurations (Class 200°C/220°C for large distribution).
- Temperature Rise: 80°C or 115°C rise over ambient
