Three Phase Rectifier Bridge Module (Low Profile of 17mm height)
DF75AC series
IF(AV)= 75A, VRRM= 800- 1800V
SanRex Three Phase Rectifier Bridge Module DF75AC series is designed for applications requiring low profile converterinverter circuit designs. Thanks to the 17mm flat case height design, the DF75AC series can be connected with IGBT or MOSFET modules at the same 17mm case height. This advantage typically reduces the needed parts and manufacturing cost. It also enables level parallel connections for larger capacity, contributes reducing stray inductance, improving high efficiency and reliability. Features
* Low Case Height of 17mm * Enable easy parallel connection * Very Low Forward Voltage Drop * High Surge Current Capability * RoHS Compliance
Isolated Package
Typical Applications
* Welding and Plasma Cutting Machines * Battery Chargers * Power Supplies * Motor Controls
