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
