Surface treatment DSP control DC rectifier High Frequency Pulse And Pulse Reverse 120VDC High
speed IGBT technology
Description
IPMA series is a line of high frequency pulse 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.

Why use IGBT pulse rectifier instead of SCR rectifier
-1.Same reliability as SCR rectifier, long time 24 hours continuous
running
-2.High frequency pulse output is good for anodizing process, get
perfect anodizing quality
-3.Power saving at least 15% than SCR rectifier
-4.Less affected by power fluctuation, 100% output, don't need
extra capacity.
-5.Less anodizing time needed, customer feedback 40% shorter time
needed
-6.High power density, compact size, much less size and weight of
SCR rectifier
-7.Low Pollution to grid, power factor>0.93
-8.Lower cost
