Product Description
The Sanzo Power TX-A5-075K-123124-AL supplies 7.5 kVA of isolated single-phase power from a 120V primary to a 120/240V secondary. Separate primary and secondary windings serve commercial, industrial and equipment distribution loads.
Construction and enclosure
Resin-encapsulated core-and-coil construction protects the winding assembly against moisture and dirt and helps control vibration. Aluminum windings use a 180°C insulation system with a 115°C temperature rise. The NEMA 3R steel enclosure supports indoor and outdoor installations.
Applications
Suitable for lighting, HVAC equipment, machine tools, pumps and general commercial or industrial power distribution. Size the transformer for the connected load and any starting requirements. Use the connection diagram supplied with the unit for field wiring and grounding.
The secondary supplies 240V line-to-line and 120V from either line to neutral. Balance 120V loads between the secondary legs.
