Microcomputer AC and DC voltage regulation (power regulation) device s

Product Description

Suitable for all kinds of silicon controlled voltage (power) control place. Especially suitable for high current (**0~***0A) occasions of reliable control, such as synthesis tower electric heating furnace of synthetic ammonia system and other high power electric heating equipment temperature control. The main circuit uses silicon controlled and diode three-phase voltage regulating line. The MICROCOMPUTER controller adopts high-performance industrial control chip, the device is stable and reliable, the sampling and output drive signals are isolated by the optical coupler, which enhances the anti-interference ability of the whole machine. Adopt digital phase shift, three-phase output voltage (or current) balance, and good linearity. The whole controller only needs to set the overcurrent protection, no other adjustment, stable and reliable work. Overcurrent trip protection. When the current of a certain phase is too large, that is, the current is greater than the setting value, the device will immediately turn off the current output of the SCR and trip off the main power supply. Overheat trip protection. When the temperature of a phase radiator exceeds *5℃, the overheating protection loop can be operated and controlled remotely. Because of the isolation of the optocoupler, the rise or fall control point is far away, but it will not be interfered by the long line.
