Solid state relays (SSR) have no physical internal contacts to wear out
and zero operating noise. Our SSR boasts 70 amps continuous, 100 amp
continuous with cooling fan. 3-32vdc control terminals (lower 2
terminals) for 12 to 24 volt systems. Works on both 12 and 24v systems!
Extremely low activation power usage allows you to connect several
relays in parallel to your charge controller without complicated runs
directly to your batteries for the control input. Run up to 50 relays
with only a 2 amp draw! The power contacts (upper 2 terminals) are NO
(normally open, not connected until 3-32volt dc power is sent to the
control terminals).
