21/136 Series - Transfer Relays
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
E13224
with a redesigned relay better suited for the low currents of LED lighting, but equally usable with
21 Series only
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
provide less power con-
sumption and less
heating.
