Single Phase Diode Bridge Rectifiers MDQ

Single Phase Diode Bridge Rectifiers MDQ AS ENERGITM in monolithic design, used in DC and AC circuits with loads to 500A and reverse pulse voltages up to 2000V.

The diode bridges are housed in a standard industrial case making it easy to easy integrate of the device into existing equipment.

An alternating current is fed to the input "~" of the circuit. In each of the half - periods the input current passes only through two diodes. As a result, at the output "+" and "-" we get a current pulsing at twice the frequency of the input current.

A filter is used to smooth out the resulting pulsating DC current, often a high-capacity capacitor.

Single Phase Diode Bridges MDQ are used in various power equipment - rectifier for power supplies; input rectifier for variable frequency drives; rectifier for DC motor field supplies; battery charger rectifiers; single phase rectifiers for power supplies; non-controlled DC motor field supply; DC power supply, for transistorized AC motor controllers.

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

The final price of diode bridges depends on the class, quantity, delivery terms, manufacturer, country of origin and form of payment.
