Used in

Common applications for FUNCTIONAL DEVICES INC / RIB
HVAC control panels — Functional Devices RIB Class 2 transformers (e.g., PSH75AB10) provide 24V AC power for thermostats, relays, and zone valves.
Lighting contactor panels — RIB power supplies (e.g., PSMN200A) step down 347V AC to 24V AC for lighting control relays and occupancy sensors.
Pump control panels — Enclosed Class 2 transformers (e.g., PSH200A) supply 24V AC to pump start relays and float switches in water/wastewater facilities.
Industrial automation — RIB current sensors and relays monitor and switch low-voltage control circuits in PLC-based systems.
Commercial building automation — Functional Devices power supplies (e.g., PSH100AB10-EXT2) provide isolated 24V AC power for building controllers and actuators.
Data center cooling — RIB transformers (e.g., PSH300A) power control circuits for CRAC units and economizer dampers.
