MK Power Supply Co.

Cathode Protection Rectifiers

As a colleague of EP–TECH, we manufacture indoor and outdoor –oil filled or dry type (air-cooled)-wall, pole or base mounting Rectifiers. Re customer requirements we produce single or three phase input (from 120V single to 600V three phase) 50 or 60 HZ.

OUTPUT

• DC volt: from 8 to 100 V
• DC Amp: from 5 to 1000A

TRANSFORMER

All transformers are manufactured and tested according to CSA, UL, ANSI and IEC standards:

• UL1561 and UL1562
• CSAC9-M and CSA C22.2-M
• ANSI C57.12.51
• NEMA TR-1and ST-1
• IEC 76

RECTIFIERS

We use variety of rectifying elements:

• 1-Silicon diodes
• 2-Selenium
• 3-Thyristor (SCR)
• 4-IGBT

CLIMATE CONDITIONS

Our Rectifiers can be manufactured for operation in the severest climatic conditions. Our outdoor units are designed to operate in ambient temperature of up to 50 C in shade, with a degree of protection against dust and water ingress according to IP55.

PROTECTION

We protect the input and output and auxiliary and control circuit with the proper protection elements according to customer requirements.

CONTROL

All generally accepted methods for the output control of chaotic protection rectifiers are available from us including:

1. Output Control Voltage by tapping on the transformer "secondary winding" according to customer requirements
2. On–load variation of output voltage by step less autotransformer connected in main transformer primary. (Control rang from 0% to 100%)

1. Constant Current Control with using a Thristor rectifier and adjust the DC output current and use the feed-back signal to adjust the proper voltage.
2. Automatic Potential Control with using Thyristor rectifier that can control DC output current in response to a signal from a permanent reference electrode

We would be glad to discuss your specific requirements more in details and please let us know how MK Power Supply could help you in your day to day operation.
