Features: This is a DC-DC step down converter power supply that converts 6V-32V to 0-32V. High precision LCD display design,make you can convenient to read voltage and current. Large 160W maximum power,meet you need,but we suggest work within 120W, reduce power when the voltage difference is large. High conversion rate, can up to 95%. Only can be used as a step down converter, and input voltage should be >1V higher than output. With RS485 communication interface, it can set up or collect data by upper computer software, or communicate with PLC, DCS, intelligent instruments and other devicesSpecifications: Type: with fan, without fan (Optional)Input Voltage: DC 6V-32VOutput Voltage: DC 0-32V (continuously adjustable)Max. Output Current: 5A(Adjustable,please strengthen the heat dissipation when the temperature exceeds 60 degrees. There is a reserved fan installation position and terminal.) Max. Efficiency: 95%Max. Power: 160W( recommended to be used in 120W) Operating Temperature: -10 to +75 Resolution: 0.01V(Voltage), 0.01A(Current) Short Circuit Protection: Yes Reverse Input Protection: Yes Output Backflow Protection: No, add a diode if use for charging Connection mode: terminal VI+ : input "+", VO+: output "+" Black wire: RS485 A , red wire: RS485 BSize: 79 x 43 x 46mm / 31.10 x 16.93 x 18.11inWeight: 73~91g Setting method:1. The output voltage setting: short press "CV", into voltage setting mode, turn potentiometer to adjust the current voltage value, press the potentiometer can switch to the decimal point before or after the decimal point to adjust the voltage value, after the adjustment, again short press "CV" save and exit. 2. The output current Settings: short press the "CC" button, enter the current setting mode, turn potentiometer to adjust the current value, press the potentiometer can switch to the decimal point before or after the decimal point of current value adjustment, after the adjustment, again short press "CC" save and exit. 3. Display MODE Settings: short press "MODE", switch display MODE, IN is display input voltage, OUT is display output voltage. 4. Switch output Settings: directly short press the potentiometer button, open or close the output terminal voltage, and the current position will display OFF when closing. 5. Address Settings: short press "SET" button, enter the address setting mode - Id, the default is 1, turn potentiometer to adjust the current address, range 1-255 , after the adjustment, short press "SET" to save and exist Package Included: 1 x Digital Step-Down Power Supply Module
