Professional DC Inverter Control Circuit Board Printed Circuit Boards PCB Assembly for Single Phase Inverter Heat Pump Water Heater, with Communication Protocol

This single-phase variable-frequency driver is one of the single-phase power supply series.Maximum input current is 10A. Rated input voltage is AC220V 50/60Hz.This variable frequency driver is controlled by a position sensorless 180 degree sine wave vector and driven by Control of BLDC Compressor.It has abnormal bus voltage and the compressor lack of phase protection, IPM module temperature protection, compressor over-current protection and other functions.The customer only needs to control the logic of the product, use standard RS-485ModBus communication to set the target frequency and read the inverter state. So it is very easy to control the compressor safely and efficiently. This controller can provides signal of DC365V and VSP to control the DC fan.

The communication between S10A01 and outdoor main control board can be separated by RS485ModMUS (optional) or RS232 (optional).Considering the requirement of universality, the default communication mode of inverter is RS485 ModMUS which communication protocol is the standard Modbus communication protocol, and the baud rate is 1200bps.The S10A01 is slave computer, and the upper computer (outdoor system main control board) is the host. The description of the communication agreement can be provided separately by contacting our company.
