Power Inverters


Inverters manufactured by Hayley Industrial Electronics Ltd. are an integral part of our UPS systems. In conjunction with our rectifiers and transfer switches, they provide continuous AC power to the load to isolate all power line interference from the load. Recent changes have replaced the forced commutation module with an IGBT module that have improved reliability and reduced the mechanical noise generated by older models.

Hayley Electronics inverters can be manufactured with inputs of 24Vdc, 48Vdc, or 1 20Vdc and outputs of 120Vac at 60 Hz or 220Vac at 50 Hz. All inverters are single phase output with a low distortion sine wave. All inverters employ active magnetic regulation and current limiting to minimize the impact of modern switching power supplies.


Industrial automation, instrumentation and all critical loads are environments ideally suited for Hayley UPS systems.

Inverter and Static Transfer Switch Sizes and Mounting

Hayley Electronics inverters are available in any specification deemed necessary to meet the needs of your operating environment. Available sizes include: 500VA, 1kVA, 2kVA, 3kVA, 5kVA, 7.5kVA, 10kVA, 15kVA, 20kVA, 25kVA, 30kVA.

Hayley Electronics inverters can be floor, wall or 19" rack mounted to best suit your environmental and space needs. Nineteen inch racks are available in 48", 60", 72" and 84" sizes.
