• Description:1 Supports a wide range of input voltages and is suitable for different types of power systems, improving the module&;s versatility and flexibility2 Using positive digital components, fastidiously tested to ensure long-term stable operation, compatible for commercial environments that require high reliability3 Equipped with constant latest output function, it is going to hold the steadiness of output latest and is suitable for purposes that require constant current4 Support continual recent output of 25A to guarantee secure operation under excessive loads5 Able to produce excessive output power, appropriate for application eventualities that require excessive calories supply, similar to industrial equipment, energy tools, laboratory equipment, etc Product parameters:Module name: 800W step-down fixed latest module/1200W step-down constant latest moduleModule nature: Non isolated voltage discount moduleModule nature: Non isolated voltage reduction module (BUCK)Input voltage: 15-90VOutput voltage range: 2 (must meet the voltage reduction condition, IN enter multiplied through 0 equals the very best output voltage)Minimum output voltage: 2 output voltage: 72V (when input voltage is 90V) Input voltage * zero is equal to output voltage (for example, if the enter is 40V, 40V * 0=32V, the maximum output voltage is 32V Input 90V * 0=72V)Output fixed current: 800W: 1 continually adjustable/1200W: 2-50A continuously adjustableMaximum output power: 800W/1200W (the operating surroundings should be effectively ventilated)Continuous operating rated power: 700W/1000W (in ventilated environment)Continuous working rated current: 25A/40A (in ventilated environment)Maximum output current: 28A/50AHeat dissipation method: air-cooled warmth dissipationInput anti opposite connection: None (input opposite connection is exactly prohibited)Input undervoltage protection: NoneInput overvoltage protection: None (overvoltage prohibited)Working temperature: -10~+65 levels CelsiusOperating frequency: 80KHzConversion efficiency: as much as 97% (efficiency is related to enter and output voltage, current, and voltage difference)Short circuit protection: Yes (constant current protection)Cooling method: Air cooling (temperature managed fan, became on at round 45 degrees)Output anti backflow: None (to payment the battery, output to inductive load, comparable to connecting to a motor, anti backflow diode should be added)Voltage and latest regulation method: (using tools similar to a multimeter and a Phillips screwdriver)Voltage regulation: Rotate the "CV" blue potentiometer on the strength board consistent with your required voltage, broaden the voltage clockwise and reduce the output voltage counterclockwise The most output voltage is about 20% less than the input voltageOutput current adjustment: Set the multimeter or ammeter to the present differ of 50A20A or 10A, alter the voltage of the flexibility delivery to 5V, turn the fixed current potentiometer "CC" counterclockwise for approximately 10 turns, alter the current to the minimum, short-circuit the output with the multimeter, after which regulate the "CC" potentiometer clockwise to adjust the present to the specified value (Note: When the fixed recent potentiometer "CC" is became counterclockwise for 10 turns, the flexibility delivery may not have output voltage because the latest is decided to 0A Don&;t fear about it, develop the present clockwise to output) Package Included: 1PCS x 1200W 50A 800W 28A DC-DC Buck Converter Step Down Power Supply Module 15-90V To 2 Adjustable Voltage Charger
