EMS – Emergency Micro Power Inverters

The EMS Series is designed to provide 20- to 55- Watts of emergency power to incandescent, fluorescent, 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 EMS provides power to the input side of the fixture, (including the ballast) eliminating any chance of incompatibility.
