1800W Specification: 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) 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) 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) Working temperature: -40~+85 degrees (enhance heat dissipation when the ambient temperature is too high), Weight: 0.95349928315 Pounds, Manufacturer: Aisuoka
