EMS750 Emergency Power Inverter

by | Apr 11, 2023 | Assembled in the USA

The All New EMS750

The EMS Series is designed to provide 750 watts of emergency power to Incandescent, Fluorescent, Induction and/or LED fixtures. The EMS unit provides clean, sinusoidal AC output power allowing it to be remotely mounted up to 1,000 feet away from the controlled fixture(s).

Unlike a ballast fluorescent emergency pack, the EMS750 provides power to the input side of the fixture (including the fixture ballast) eliminating any chance of incompatibility. The EMS Series is designed for surface mounting. All EMS systems will provide emergency power output for a minimum of 90 minutes.

Features

  • Input circuit breaker included as standard
  • For powering incandescent, fluorescent, induction and LED fixtures
  • Sinusoidal output eliminates compatibility problems
  • Universal 120/277VAC, 60Hz input/output
  • “Soft Start” design reduces fixture inrush current
