The MM1000A is a lower cost alternative to the MM1000 DC limit alarm for standard applications. The MM1000A monitors a DC input and trips a dpdt, 5 A relay when the input exceeds the desired level. The alarm has a green LED to indicate relay status.
Setpoint adjustment is provided by a 25-turn trimpot, adjustable from below 0% to above 100% of span.
Deadband, also a 25-turn trimpot, is adjustable from below 1% to above 100% of span. A user-changeable jumper may be changed to provide high or low trip.
All Wilkerson products are designed with RFI filters and lightning protection to reduce susceptibility to electrical noise and damage by lightning.
For options or input ranges not provided by MM1000A, refer to MM1000 or FR1000.
