Product Description

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.

S10A01 Functional Specification:
Communication
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. 
Frequency control 
Up / down rate control
After the start process, if the target frequency is higher than the current running frequency, the target frequency will rise to the target frequency at the rate of 1.5Hz/S.If the target frequency is lower than the current value, the target frequency is reduced to the target frequency at the rate of 1.5Hz/S. Stop: when set the stop or failure protection, the controller immediately shuts down the drive signal, and the compressor shuts down automatically.
After shutdown, the compressor starts again for 10 seconds. After 150 seconds, the inverter will be error-clearing and waiting for the master command.
Protective Functions
IPM temperature protection
The controller is designed with IPM temperature protection function to avoid damage to power devices due to excessive temperature.Specific protection functions are as follows:
When the temperature of the IPM sensor is in the image
Area [0] Compressor running Hz Free
Area [1] Compressor running Hz Frequency reduction 10Hz
Steady for eight minutes, if you're still in the region.
Then the 2Hz is continuously reduced and stabilized for 2 minutes.
Area [2] Stop protection for 5 seconds in this area. 
(The temperature control point can be adjusted according to the radiator or other factors)
We also send you the Modbus communication protocol.  This is to help your air conditioner mother board to control the compressor. 
And then the compressor can send directions to your DC inverter air conditioner unit and drive its operation.
