Special Features

  • Digital control adjustment, precise and convenient, can increase or decrease voltage. Input voltage range DC 5 - 30V; The output voltage range is DC 0.5 - 30V, which can be adjusted arbitrarily; The output current can reach 3A for long-term use, and if heat dissipation is strengthened, it can reach 4A; The maximum output power is 35W, and if the heat dissipation is strengthened, it can reach 50W.
  • LCD can display input / output voltage, output current / output power / output capacity / output time.
  • Input end anti reverse connection protection, reverse connection will not burn out; Output end anti backflow protection, there is no need to add an additional anti backflow protection diode when charging the battery.
  • It has various software protection mechanisms such as input undervoltage protection, output overvoltage protection, output overcurrent protection, output overpower protection, over temperature protection, timeout protection, and over capacity protection, and the protection threshold is adjustable. When the working parameters of the module exceed the protection threshold, the output will be automatically turned off.
  • Module can be set to default on/off; Equipped with a π - type filter, the output ripple of the module is small; Equipped with thickened heat dissipation fins.

Place of Application:
- Can be used as a regular step-down / step-up module with overcurrent protection.
- Used as a constant current drive module, such as LED dimming, battery charging, and motor speed regulation.
- DIY solar power supply controller.
Note:
- Constant voltage and constant current cannot work simultaneously. When set to constant voltage, constant current cannot be maintained, and when working with constant current, constant voltage cannot be maintained. The constant current function is only suitable for specific places, such as LED dimming, battery charging, motor speed regulation, and other typical constant current work situations.
- The input port
- Please ensure that the power of the power supply is always greater than the required power for the output load.
- When using this module beyond 3A and 35W, please strengthen heat dissipation.
Package Include:
1 x Variable Voltage Regulator
