PS220/PS220BB Power Supply

The PS220/PS220BB series power supplies are a high quality, cost effective solution for powering two electric latch pullback exit devices. 

These power supplies provide the necessary surge current that most latch pullback exit devices require. The PS220/PS220BB series offers features found on power supplies costing much more.

The solid-state design and careful attention to detail make these power supplies the ideal choice for the discerning user who requires a power supply that can offer years of trouble-free operation.

Features

• UL Listed
• CSA Listed
• Delivers the necessary in-rush current to power two latch pullback exit devices.
