Input voltage: 5 ~ 30V
Output voltage: 0.5 ~ 30V
Output current: 3A (add heat up to 4A)
Output power: 35W (add heat up to 60W)
Output ripple: 20mV (12V 3A), while the common module is far more than 100mV!
Conversion efficiency: 87 ~ 91%(Boost); 87 ~ 89%(Buck)
- Automatic Boost or Buck: No matter if the input voltage is higher than 12V or lower than 12V, the voltage can be constantly output 12V.
Input Voltage: DC 5-30V
Output Voltage: DC 0.5~30V
Output current: 3A (long-term stability work); 4A (strength reduction can be achieved)
Output power: 35 W (naturally sinking); 60 W (strength sinking).
Switch efficiency: Boost voltage 88 ~ 91%; Buck voltage 87 ~ 90% (it will change depending on voltage difference and load).
Operating frequency: 180kHz
Board Size: 68 x 29 x 21mm
Instructions for use:
The standard factory output voltage is set to 12V, and the default constant current value is set to 2A. Please adjust the output constant current to avoid load damage.
The larger potentiometer with multiple rotations is used to adjust the output voltage. The shorter rotation potentiometer is used to set the constant current value. If you need to increase voltage or current, please set the corresponding potentiometer clockwise. To decrease, turn the corresponding potentiometers counter-clockwise.
Indicator in full charge: a red LED shows constant current output. A blue LED indicates the charging. A green LED indicates that the charging current is less than a tenth of the set value.
Directions for use:
1. Very suitable for the device with large input voltage range and constant output voltage, such as constant voltage battery, solar power generation, power module.
2. Constant voltage (e.g. For example, mobile phone charger or battery charge) can get DC 0.5 ~ 30 V adjustable power.
