Features

  • Low/high battery protection – If your battery voltage reaches below 10 VDC or above 17 VDC, the MMS Series will automatically shut down.
  • Versatile mounting – Mount the MMS Series on a shelf, bulkhead, or even upside down.
  • Fan cooled – The MMS Series is fan cooled, enabling the unit to work well in confined spaces. If the inverter does exceed its temperature limits, it will automatically shut down and then restart when it cools down.
  • Current overload protection – The MMS Series will automatically shut down if its output wattage is exceeded or it detects a short in the wiring, saving the unit from costly damage.
  • Convenient switches – The MMS Series comes with an on/off front-mounted switch with an easy-to-read LED indicator.
  • Circuit breaker protection – This model comes with built in input and output circuit breakers for ease of installation.
  • Battery temp sensor – The standard battery temp sensor monitors temperatures from 0 - 50° C.
  • Buy with ease – The MMS Series is backed by a two-year (24-month) parts and labor warranty.
