DC Rectifiers 160VDC 300A High Frequency High power Programmable DC
power supply
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 three-phase 380VAC 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.
Application
It is widely used in Electrochemical,surface treatment, shipbuilding industry, the petrochemical and power supply system, industrial control, electronic power,surface treatment, scientific
research, instrumentation, military industry and other high-tech
fields.
