Output current: 20A MAX More than 15A, please strengthen the heat dissipation (related to the input and output voltage difference, the larger the differential pressure, the smaller the output current) Static working current: 15mA (12V liters 20V, the higher the output voltage, the static current increase); Output voltage: 12-90V continuously adjustable(default output is adjusted to 19V shipment, please adjust to other voltage values. If you have a multimeter buyer can adjust it); 12-90V fixed output (for volume customers) 1800W Specification: Constant current range: 0.8-20A (+/-0.3A); Input anti-reverse connection: Yes (150A power MOS anti-reverse); Low battery protection: self-recovery (8-50V adjustable) Working temperature: -40~+85 degrees (enhance heat dissipation when the ambient temperature is high), Manufacturer: Jnchdghwa
