Contactor/Diode OVL

The Micha range of Contactor-Diode Over-Voltage Limiters are available in a range of specifications according to the customer’s requirements. Because of the wide variation in currents and voltages, each is made to order to meet the end user’s needs. All work on the same principle. A number of diodes are wired in series with the Live output and under low voltage conditions, a normally-closed contactor shorts each diode (or pair of diodes). As the source voltage rises, the contactors sequentially open, introducing a voltage drop across the diodes and thereby reducing the voltage seen at the Output.

  • 50A to over 200A power rating
  • Available as kits for end user to fit in their own cabinets
  • Voltage drop defined by number of series diodes
  • Programmable mode of operation
  • Microprocessor controlled with 2 x 16 LCD display
  • Power-saving contactor switching
