40VDC programmable DC power supply IGBT rectifier micro-arc
oxidation surface treatment Rectifier
Description
IDMA series is a line of high frequency DC rectifiers designed to
meet all galvanic surface treatment requirements. Based on high
speed IGBT technology, they provide high efficiency and
performance. Supported 342VAC to 418VAC three-phase voltage input,
output voltage and current can be customized, Low Ripple,IMAX
rectifiers adopt pulse width modulation (PWM) technique for the
controlling of current amplitude and adopt full digital design,
using TI 12-bit DSP control.
