High-power relay designed for lighting industry

The HF115FS is capable of switching an incandescent lamp load of up to 3,000W at 230V AC.

Specifically chosen for this arduous application, its contacts are made from W+AgSnO2 (Tungsten plus Silver Tin Oxide) and are rated at 16A 250V AC.

The HF115FS package measures 15.7 x 12.7 x 29mm and is available with 5, 6, 9, 12, 18, 24, 48, 60 and 110V DC 400mW operating coils.

It is approved by cULus, VDE and CQC approval laboratories, and a version of the HF115FS is available in accordance with IEC 60335-1 and is suitable for use in household equipment.

The HF115FS has a maximum switching power of 4,000V/A and specifies a creepage and clearance distance of 10mm.

Contact resistance is 100mohms (at 1A, 6V DC).

The relay has a 5kV dielectric strength between coil and contacts, and it has mechanical endurance figure of 5 x 106ops.

Hongfa has added this relay to its HF115F series of relays, which also includes the standard HF115F/HF115FA 12A and 16A single-pole relays, and 8A double-pole relay with AC and DC coils.

The series also embraces application-specific relays such as the HF115FH with high-sensitivity DC coils; the HF115FT with a temperature rating of 105C; HF115FI high-inrush relay with a TV5 80A rating; the HF115FQ with 6.3mm Faston quick connect terminals; and the HF115FP with mechanical test button and built in LED.
