Features: This is a DC-DC automatic Step-up Step-down converter power supply that converts 6V-32V to 0-30V. High precision LCD display design, make it 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%. With RS485 communication interface, it can set up or collect data by upper computer software, or communicate with PLC, DCS, intelligent instruments and other devices Specifications: Type: with fan, without fan (Optional)Input Voltage: DC 6V-32VOutput Voltage: DC 0-30V (continuously adjustable)Output Current:Max.5A(Adjustable,please strengthen the heat dissipation when the temperature exceeds 60 degrees. )Efficiency:Max.95%Power:Max.160W( recommended to be used in 120W)Operating Temperature: -10~75Resolution: 0.01V(Voltage), 0.01A(Current)Short Circuit Protection: YesReverse Input Protection: Yes Output Backflow Protection: No, add a diode if use for chargingSize: as the picture Weight: 148-165gConnection mode: terminal VI+: input +, VO+:output + Black wire: RS485 A, Red wire: RS485 BSettings: 1.Output voltage setting: short press "CV" button, enter the voltage setting mode, turn potentiometer to adjust the current voltage value, press the potentiometer can switch to the voltage value of decimal point before or after the decimal point to adjust, after the adjustment, short press "CV"again to save and exit 2.Output current setting: short press "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 to adjust,after the adjustment,short press "CC"again to save and exit. 3.Display MODE setting: short press "MODE", switch display mode, IN: display input voltage, OUT : display output voltage 4.Switch output setting: directly short press the potentiometer key, 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
