Digital Power Supply Controller for Master/Slave Control

CO-MS series is a control unit to perform master/slave control operation*2 of all the power supplies with -LGob option*1 produced by Matsusada. With the control unit, up to 32 power supply units are available for parallel or series operation.
Also, it is capable of tracking the total sum of the output voltage at series operation or the output current at parallel operation.
You can readily control the power supply*3 using the switches and dial on the front panel.
Thanks to the optical communication system between the unit and the power supply, the unit is less affected by external noise or ground loop problems.
And, if necessary, you can select optional interfaces of LAN (Ethernet*4), /USB/RS-232C/RS-485/GPIB which enable the remote control.

  1. Compatible with Ver.6.2.0 or later
  2. There is no such a function as divides the output value of power supplies evenly.
  3. When Master-slave control is working, the load variation of the output voltage of power supplies will be around 0.5% max.
  4. Ethernet is a registered trademark of Xerox Corporation.

Features and Benefits

  • Up to 32 power supply units are available for parallel or series operation
  • Strong optical communication to noises between the unit and the power supply
  • Clear LCD display
  • Simple operation in sophisticated design
  • Total output voltage or current can be read
