Max. Input Current: 30A(input voltage 10V to 30V) or 25A(input voltage 31V to 60V)
Quiescent Current: 15mA(will increase when convert 12V to 20V)
Output Voltage: 12V to 90V (adjustable, default is 19V) Max. Output Current: 20A (related to the input and output voltage difference, the greater voltage difference is, the smaller output current will be. please enhance heat dissipation when current is over 15A)
Constant Current Range: 0.8A to 20A(+/-0.3A)
Reverse Input Protection: Yes (150A MOS)
Lower Voltage Protection: Yes (V8 to 50V adjustable, self-recovery)
Operating Temperature: – 40℃ to +85 ℃(if temperature is too high, please enhance heat dissipation)
Conversion Efficiency: 92% to 97%
Input Over-current Protection: Yes (automatically protect when input is more than 35A, and power supply voltage will not increase)
Short Circuit Protection: Yes(input 30A fuse)
Wiring Method: Terminals(please use large current copper wire)
Max. Output Power = Input Voltage*Max Current (If input 12V, the max output power=12V*30A = 360W)

1 x Module
1. Output wiring can not be reversed or short circuit.
2. If the module is connected to inductive load, the minimum input voltage should be higher(e.g. 24V) and maximum output power should be lower(e.g. 500W).
3. If a storage battery, switch power supply, solar panel or electric generator is used as input power source, the low voltage protection value should be adjusted lower, otherwise it might cause damage.
Module output should not short circuit or measure current directly with multimeter short circuit, short circuit will burn out module.
Under voltage adjustable range:DC10V-50V (clockwise to increase, counterclockwise to reduce), firstly adjust under-voltage to the minimum, then adjust input voltage to required under-voltage protection value, slowly adjust under-voltage value clockwise to increase; when the under-voltage light is on, adjust counterclockwise of one circle, then power on again.
Input under-voltage protection mainly used to prevent battery from over-discharging when input power source is battery. Low battery voltage will damage power module and battery. When input is switching power supply, it also need to set the low voltage protection.
Constant voltage adjustable range:DC12-97V(clockwise to increase, counterclockwise to reduce), first adjust voltage to the required voltage and then connected to the load.
Constant current adjustable range:0.8-22A (clockwise to increase and counterclockwise to reduce), first disconnect load, then adjust output voltage to required voltage, adjust current to the minimum (counterclockwise turn CC potentiometer about 30 circles), connect an ammeter in series to the output, then slowly adjust current.(booster module cannot directly adjust current by short circuit)
Input voltage should not be lower than 10V or higher than 60V, (when input voltage is lower than 12V, please properly reduce the load).
Make sure the input voltage is at lease 2V lower than output voltage.
If use switching power supply or other secondary power supply, please make sure that power is 1.3 times greater or more than the power supply module’s power.
During over current or under-voltage protection, output will still have voltage that is close to the input voltage, protection means no boosting voltage.
