The 21 and 136 series flash transfer relays have a proven industry record of reliability. Their

rugged design has allowed the products to be plugged in and left, for years of service.

Recent changes in lighting techniques from incandescent to LED have prompted us to respond

with a redesigned relay better suited for the low currents of LED lighting, but equally usable with

tungsten lamps.

The 21 series coil is

rectified which provides

chatter free operation in

brownout conditions down

to 85VAC and will not

overheat up to 130VAC.

Rectified coils also pro-

vide less power consump-

tion and less

heating.
