产品描述

Product features

▲Adopt all-digital humanized design, simple and quick operation.

▲The control core adopts 16-bit microprocessor and advanced SMT welding technology.

▲The signal input and output interface adopt isolation technology, which has strong anti-interference ability.

▲ A/D high precision conversion, high control precision.

▲ Open-loop phase shift, closed-loop constant voltage (constant output voltage), closed-loop constant current (constant output current), power adjustment (fixed period, variable period) control and other control modes are integrated, making the use more flexible.

▲It is equipped with standard RS485 communication interface, which is convenient to realize centralized control of multiple units.

▲The product quality is stable and reliable, and it has been widely used in vacuum, nuclear power, glass, air separation, ceramics, non-ferrous metals, packaging machinery and other industrial fields.
