300W 20A DC Buck Module Constant Current Adjustable Step-Down Converter Voltage
Description:
It is possible to get changeable output voltage ranges between 1.2V and 36V using the 300W 20A DC-DC Step-down Adjustable Constant Current Module. The module has several current output ranges up to 20 A. It is easy possible to operate high power applications continuously with the heat sink fitted (provided that for continuous high power output you need to use a cooling fan on the heat sink).The Module is created with a specialized benchmark IC and a high-precision current sensing resistor, providing in a more stable constant current (when the constant current is 1A from 20C to 100C, temperature drift is less than 1%), made it extremely well suited for LED driver applications. The module’s output current may be increased to 20A. (for continuous use it is recommended up to 15A with an additional cooling fan).
Features:
LED driver with high power.
Charge from a lithium battery (or a lead accumulator).
power source installed on a vehicle.
system power supply with low voltage.
Battery charges at 6V, 12V, 14V, and 24V.
laptop power supply built-in.
provision of controlled electricity.
system for low-voltage power delivery.
Specifications:
Output Current: 20A(max.), 15A (suggested)
Output Voltage: 1.2V to 36V DC
Efficiency: 95% (24V to 12V, 20A)
With a wide input voltage range from 6V to 40V (10V to 40V is suggested), the step-down converter can accurately adjust output voltage and current
Output Ripple: Less than equal 50mV
Wiring Method: Terminal
Short Circuit Protection: Self-recovery (cannot short circuit for long time)
Stable and reliable
Fine workmanship and durable
Pinouts:
VO+: Output positive
VO-: Output negative
+IN: Input positive
-IN: Input negative
CV: Output voltage adjustment
CC: Output current adjustment
EN: Enable, low voltage level shut off output; suspension, high voltage level is effective
Precautions:
When input and output is common grounded, no-load CV output constant voltage, CC output constant current
Working Temperature: -10Celsius -75 Celsius
Designed with 75V/80A large current dual MOS tube
The buck module has 2 heat sink that could enhance heat dissipation
Wiring is convenient with these large current 30A screw terminals
Input and output use high frequency low resistance electrolytic capacitor, low ripple, stable output
Uses:
Widely used in industrial Automation, scientific Research Equipment, LED Lighting, air Purification, civil equipment, solar panel voltage regulator, battery charging wind turbines and so on.
Note:
Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
The measurement allowed error is +/- 1-3cm.
