Hongfa’s HF3FA and HF115F relays have been designed specifically for lighting control systems. Working in conjunction with PIR or other sensors the relays may be used in in building automation, energy conservation, safety and security systems. The HF3FA sub-miniature relay measures 19.00 x 15.20 x 15.50mm and provides a 15A switching capability with either a normally open contact or change-over configuration.

Housing material flammability meets UL94, V-0, UL Class F insulation is available and electrical breakdowncomparative tracking index to CTI 250 may be specified. Coil operating voltages for the HONGFA HF3FA may be specified as 3, 5, 9, 12, 18, 24 or 48VDC.

Two models of the HF115F relay are available both with either normally open or change-over contacts. The HF115F-I has a high inrush capability of 80A at 125V and the HF115F-S features a special contact construction capable of switching an incandescent lamp load up to 3000W 230VAC with a peak inrush capability of 800A.

Both models provide a 5KV dielectric strength, meet reinforced isolation requirements, have a creepage distance of 10mm, low package size with overall dimensions just 29.00 x 12.70 x 15.70mm. UL Insulation Class F and IEC 60335-1 if may be specified if required. The HF115F-I and HF115F-S may be ordered with coil voltages over the range 5, 6, 9, 18, 24, 48, 60 and 110VDC.

All HONGFA lighting relays may suppliedflux proof for use in contaminate free, clean areas or plastic sealed for use in dusty or harsh environments, are designed for PCB mounting and are RoHS compliant. HONGFA relays meet the safety requirments ot VDE, UL/CUL, TÜV, and CQCand have a life expectancy of up to 100,000 operations depending on model and load.
