Each E-Flex relay panel (EFRP) can provide 24 VDC power for some number of input control
devices – occupancy sensors, daylight sensors, CapT stations, etc. The charts below provide
power supply load information for the E-Flex.

*A unit load is defined as 50mA.
Note:
If the total unit loads is greater than the capacity of the EFRP, install an LPS-
20UL link power supply, P/N H4017. This is +24V with 20 unit load capacity
and 120V/277V AC input.
