Parameter:
Module nature: non-isolated buck module (BUCK)
Input voltage: DC15-90V
Output voltage range: 2.5-72V (must meet the buck conditions, IN input multiplied by 0.8 equals to the highest output voltage)
Output minimum voltage: 2.5V
Output maximum voltage: 72V (input 90V voltage) input voltage * 0.8 is equal to the output voltage (for example, input is 40V, 40V * 0.8 = 32V maximum output voltage is 32V. input 90V * 0.8 = 72V)
Maximum output current: 50A
Maximum output power: 1500W (working environment must be well ventilated)
Maximum output current: 50A
Cooling method: air-cooled cooling (about 50 degrees to open the fan, 40 degrees off the fan)
Input anti-reverse connection: No (strictly prohibit input reversal)
Over-voltage protection: No (prohibit over-voltage)
Operating temperature: -10~+65°C
Operating frequency: 80KHz
Conversion efficiency: up to 97% (efficiency and input and output voltage, current, pressure difference)
Short-circuit protection: Yes (current limit 50A protection)
Output anti-reflux: No (output connected to inductive loads, such as connected to the motor must be added anti-reflux diode)
Precautions:
1. This power supply is a step-down power supply, the output voltage can only be lower than the input voltage
2. There is no reverse input protection, positive and negative reverse connection is strictly prohibited.
3. Because the output current can not be adjusted, can not charge the battery, the output is connected to the inductive load, the output should be added to prevent the return of the diode * long time high-power, high-current do a good job of heat dissipation.
4. In the selection of power supply, the power supply power should be greater than the load power 1.5 times or more
Package include:
Adjustable buck module *1
