Von Duprin PS904-4RL Base Power Supply, 4 Relay Board Output

Von Duprin PS904-4RL Base Power Supply, 2 Relay Board Output4RL:

4 relay distribution board with logic is field configurable for time delay function, auto operator, security interlock

Overview:

The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. There are different types of power supplies and many can be configured in a variety of ways. It is important to understand the basics of electricity as well as the operational requirements of the opening before getting started.

The Schlage PS904 4-amp power supply is designed to deliver a highly filtered and regulated "clean" output to protect downstream devices.  The PS904 is factory and field configurable to suit specific needs. Separate battery management extends battery life and ensures consistemt output.
