Dual diode rectifier module MDC 800-18 AS ENERGITM in an international standard package, 800A 1800V.

The diode modules MDC800-18-410F3 are characterized by high electrical and thermal cycling capability, meaning high reliability and long lifetime in intensive operation modes. The diode modules are housed in a industry-standard housing making it easy to integrate the device into existing equipment.

The two-position modules have different switching circuits (electrical circuit diagrams): МDChalf-bridge; МDKscheme with common cathode; МDAscheme with common anode.

Series (ratings) of diode modules: MDC800-6 (800A 600V), MDC800-7 (800A 700V), MDC800-8 (800A 800V), MDC800-9 (800A 900V), MDC800-10 (800A 1000V), MDC800-12 (800A 1200V), MDC800-14 (800A 1400V), MDC800-16 (800A 1600V), MDC800-18 (800A 1800V).

The main (power) terminals are on the top of the case and are marked as 123 (common anode-cathode, cathode, anode).

Dual diode modules MDC series are used in various power equipment - power and control units, power regulators, AC regulators, DC motors control, AC motor soft starters, converters, controllers of blast furnaces or chemical processes, welding equipment, and as rectifiers for AC converters.

Our modules are offered in several dual and single device topologies for almost all phase control or rectifier applications.

Our company provides a quality guarantee for thyristor / diode modules of 2 years from the date of purchase. When supplying thyristor / diode modules, if necessary, we provide technical passport and certificate of conformity.
