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.
