Features:
- Fixed turn lamp current is 0.1 times the current value ( Used to identify whether the battery is fully charged When charging).
- Made from a dedicated benchmark IC and high-precision current sensing resistor, proving a more stable constant current, (when 20°C to 100°C constant current 1A, temperature drift less than 1%). Particularly suitable for LED.
- High output current, the max output current can reach 8A.
- Four high frequency capacitance, can lower output ripple, enhance the work stabilization.
- Double heat sink design. MOS schottky diode independent heat sink,which heat dissipation is good,and won't affect each other.
- Using large size Sendust Core and double pure copper wiring, improve working efficiency, reduce fever.
- 3296 multiturn potentiometer,high accuracy voltage and current regulation, good stability.
- Double color lamp, working condition be clear at a glance
- Voltage and current are adjustable,wich effect is good.
- Output Voltage: (1) DC 1.2-28V continuously adjustable. (2) Fixed output:Choose between 0.8v-28v
- Output Current: 8A (when power tube"s temperature exceeds 65 degrees, please add cooling fan)
- Constant Current Range: 0.2-8A (Adjustable)
- Turn Lamp Current: Constant current value * (0.1), turn the lamp current and constant value linkage, such as constant current value is 3A, turn the lamp current is set to a constant current is 0.1 times (0.1 * 3A = 0.3A)
- Output Short Circuit Protection: Yes, constant current
- Input Reverse Polarity Protection: None
- Output Prevent Backflow: None
- Wiring: Terminal
- No-Load Current: Typical 20mA (24V switch 12V)
- Load Regulation: ± 1% (Constant)
- Voltage Regulation: ± 1%
- Dynamic ResponseSpeed: 5% 200uS
- Potentiometer Adjustment Direction: clockwise (increase) , counterclockwise (decrease), the potentiometer(CV) closed to the input voltage is used to regulate voltage, the potentiometer(CC) closed to output voltage is used to regulate current (CC)
- Operating Temperature: Industrial grade (-40 °C to +85 °C) (please note the actual use of the power tube temperature , high temperature heat strengthened)
- Indicator: dual color indicator, charging indicator light is red, the green light means fully charged (No load is green)
- Size: Approx. 65 x 47 x 23.5mm/2.56 x 1.85 x 0.93""
- Precision of Constant Current and Temperature: On the actual test, the module temperature from 25 degrees to 60 degrees, the constant current value change is less than 5% (5A constant current value)
- Output Short Circuit Protection: Yes,Constant current (the current setting constant current value)
I love these supplies. I used them to build a variable DC supply for my bench. I changed the pots for panel mount 10 turn pots and fed these supplies(3) with a high current 24V supply. Most of the parts for this project were source from banggood including the laser to engrave the front panels.
Incrivelmente pequeno, mas muito bom! A encomenda chegou sem atrasos e sem problemas, nada danificado e bem embalado. Já testei e fiquei muito contente, coloquei na entrada 22 Volts DC retirados da minha fonte e foi regulando a saída e tirei várias voltagens como podem ver nas fotos. Por isso recomendo, não aqueceu e por fim digo que é um bom regulador de DC para DC. Temos que ter atenção em não ultrapassar a voltagem máxima permitida pelo fabricante.
