DC Rectifier 380VAC input High Frequency DC Power Supply 400VDC 3
Phase AC To DC Rectifier
Description:
IDMA series is a line of high frequency DC rectifiers designed to
meet all surface treatment requirements. Based on high speed IGBT
technology, they provide high efficiency and performance. Supported
three-phase voltage input, output voltage and current can be
customized, Low Ripple,Our rectifiers adopt PWM technique for the
controlling of current amplitude and adopt full digital design,
using TI 12-bit DSP control.
