MWS440 Series Relay Switch
These MWS440 series continuous duty relays are sold in non-grounded insulated cases (lightning proof). They are made for Missouri Wind and Solar only.
Available in either 12-15 activation volts or 24-30 activation volts. Use for building your own controller or to upgrade your existing controller.
Great addition to a dump load for diverting or controlling wind and or additional solar up to 10,000 watts on many PWM or MPPT charge controllers.
These are not like standard relays that can only run for a short duration before burning up but are true industrial duty models that are not bothered by heat, dirt, or continuous ON time!
