Three-Phase Full-Wave Rectification

The MDS35E-16 uses a conventional three-phase diode bridge arrangement to convert three-phase alternating current into pulsating DC power.

This type of rectifier is commonly used in industrial equipment where three-phase AC power must be converted into a DC bus for subsequent filtering, switching or inverter operation.

35A / 1600V Power Rectification

The MDS35E-16 designation is commonly associated with a 35A, 1600V three-phase rectifier. Actual current handling depends on the manufacturer specifications, case temperature, heatsink performance and operating conditions.

Compact Heatsink-Mount Design

The module features a central mounting hole for mechanical attachment to a suitable heatsink or mounting surface. Appropriate thermal installation helps transfer heat away from the rectifier during high-current operation.

Typical Applications

• Industrial Welding Machines
• Variable Frequency Drives (VFD)
• Industrial Motor Inverters
• Three-Phase AC-to-DC Power Supplies
• Industrial Rectifier Circuits
• Motor Control Equipment
• Industrial Automation Systems
• Power Conversion Equipment
• Inverter Repair and Maintenance
• Industrial Power Electronics

Installation and Compatibility

Before installation, verify the exact terminal configuration, input phases, DC output polarity, electrical ratings and mounting dimensions against the original module and manufacturer datasheet.

For high-current operation, use an appropriately rated heatsink and suitable thermal interface material. Installation should be performed by a qualified technician because the device is intended for hazardous high-voltage power circuits.
