1C31194G04 - Valve Positioner

Description

Rectifier module features ➢ Soft switch ➢ Limited power control ➢ Short-circuit recoil protection ➢ Hot swap ➢ Protection and fault alarm ➢ Low pressure difference autonomous flow sharing ➢ Stepless flow limiting ➢ Monitoring and three remote functions ➢ Dust prevention and fan speed regulation

Soft switch - The power circuit of the rectifier module is divided into two parts: active PFC correction and full-bridge DC/DC conversion. Full-bridge DC/DC conversion adopts full-bridge phase-shifting soft switching technology. It achieves a wide input voltage range (1 20V~290V) and high efficiency (88%), and the power density reaches the international advanced level. Low difference autonomous flow sharing - The rectifier module automatically equalizes the flow by using the low-voltage difference between modules. If the monitoring module or a certain rectifier module is faulty, the other modules can equalize the flow. Stepless current limiting technology - The rectifier module adopts stepless current limiting technology. Under the control of the monitoring module, the current limiting point can be continuously adjusted from 0 to 105% of the rated current. Feature - The rectifier module has a built-in CPU that monitors and controls the running status of the module and communicates with the monitoring module. The rectifier module receives the on/off command, current limiting point, voltage setting and other parameter setting commands sent by the monitoring module through RS485, and sends the voltage, current, temperature, current limiting point, on/off and alarm quantity of the module back to the monitoring module in real time, completing the control of the monitoring module on the rectifier module.
