SCHLAGE - PS902-4RFA Schlage Electronics PS902 2-Amp Class 2 Power Supply with 4-Relay Output Board and Fire Alarm Interface Board, 12/24VDC Output, 120/240VAC at 50/60 Hz Input

The Schlage Electronics PS902 2-amp Class 2 power supply operates on 120 to 240V at 50/60 Hz to power 12 or 24V access control systems (sold separately) and includes an output board with four relays as well as a fire alarm interface board. The power input has a fuse to prevent system damage if the current limit is exceeded. The field-selectable 12V or 24V power output is regulated and filtered for a constant output rating and is limited to prevent excessive output current. LEDs indicate when input and output voltage is present. The enclosure meets NEMA Grade 1 standards and has a gray baked-enamel coating as well as a hinged cover that protects against high voltage. The included output board has four relays to connect multiple devices (sold separately), and the included fire alarm interface board enables both switched and unswitched output, which can be activated by the signal. Additional boards (sold separately) connect using the supply's polarized locking connectors and mount flat inside the enclosure, eliminating the need for racks and side connectors.SpecificationsSpecifications metUL 294 certified, Class 2, RoHS, and FCC Part 15.
