REQUEST ADDITIONAL INFORMATION:

COMMANDER II -48V DC Power System
COMMANDER II+ -48V DC Power System
  • 7U Rack mount shelf w/ power distribution
  • Up to 8 RM3048HE 48V Rectifiers
  • Up to 8 CM12-40 or CM24-40 (choose one voltage only, no mixing)

Complete system design and integration by Newmar to your application parameters: Rectifier configuration, installation of distribution circuit breakers, and configuration of alarms and monitors. Assembly in a relay rack with batteries and wiring also available.

Let us submit a proposal on your next project. All system components are sold separately.

Monitoring & Control

The Commander II series is designed to allow a customized DC power solution with all the benefits of a standard “off the shelf” system. The system is intended to be a complete power system in a box with no connections needed to be made internally. The system is designed to be extremely simple to install and set up. The Commander II series access to system parameters and alarms through the integrated touchscreen display or accessed via the integrated web server and custom GUI. The system provides remote notification and monitoring via RS232 or TCP/Ip (using SNMP). All the DC connections are made from the front of the unit, AC on rear. The system can be customized to suit most requirements whilst maintaining a robust and smart user experience. 

General System
