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.
Current Limit: Adjustable to 50-100% of maximum rated current.
Over Temperature: Automatic current reduction, backup shutdown protection.
Polarity Reversal: Output fuse with crowbar diode.
Over Voltage: Adjustable limit.
Input Voltage: Auto shutdown, auto restart when correct voltage restored.
Input Inrush: Input Fuses: In both phases.
