the key of coding potentiometer briefly to activate the parameter to be set;The switch of parameter name and bit selection is realized by short pressing the key of coded potentiometer;After selecting the parameter name, the parameter name be displayed in reverse blue, and the parameter to be set be switched by rotating the encoding potentiometer; After bit selection, the corresponding bit be displayed in reverse blue, and parameters be set by rotating encoder;After the setting is completed, long the key of the encoding potentiometer for 2 seconds or more, and no key operation automatically exit the setting;All parameters are saved automatically after exiting. Data group function description:10 sets of data groups of M0-M9 can be saved. By default, the data group M0 can be saved. and hold the key of coding potentiometer for 2 seconds on any interface to quickly call up the M1/M2 data group, and the serial number of the current data group be displayed at the interface index; In the power parameter setting interface, select the data group, and rotate the encoding potentiometer to call up the corresponding data group; After the parameters in the data group are modified and exited, the corresponding parameters be stored in the current data group by default. Set voltage U-SET:0.6-36V; Set current I-SET:0-5.1A; Input undervoltage protection default: 4.8V, self setting; Output overvoltage protection OVP default: 37V, can be set by itself; Output over-current protection OCP default: 5.2A, can be set by yourself; Output over power protection OPP default: 81W, self setting; Maximum operation time OHP: when the parameter is not set to 0, turn on this function. When the operation reaches the set time, the power automatically turn off the output; Maximum capacity : when the parameter is not 0, turn on this function, when the capacity reaches the set parameter, the power automatically turn off the output; Maximum energy OWH: when the parameter is not 0, turn on this function, when the energy reaches the set parameter, the power automatically turn off the output; OHP / / OWH function can well realize timing / quantitative power supply. colour: black Material: plastic size: 79 * 42 * 22MM Package Contents: 1*Buck Boost Converter Note: power output is off by default after data group switching; Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
