Blue Sea 1836 OLED AC Ammeter

Digital monitor with OLED  display monitors AC amps on up to two external sensors.  The meter comes with a single current transformer that reads up to 150 Amps and to read a second circuit an additional current transformer is required.  Other current transformers are available that can read up to 300 Amps.  The gasket creates a waterproof seal on the unit face.  The M2 Monitors include a MOSFET External Circuit Relay (ECR) which can be used to control external circuits based on any value measured by the M2. The M2 External Circuit Relay is separate from and independent of the Internal Alarm function.  A DC power supply is required to run this meter, it can be between 7 and 70 Volts DC
