Precautions:
1. The input cannot be connected to AC power, nor can it be connected to 220V mains power.2. The maximum input voltage must not exceed 145V. It is recommended to use with in 140V, and the positive and negative terminals must not be connected reversely.3. The output has no reverse current protection. When connecting the battery, ensure that the power supply's output voltage is always higher than the battery voltage. Alternatively, a diode can be connected in series with the positive output terminal to allow one-way conduction, preventing reverse current from the battery voltage from damagingthe power supply.4. When connecting the battery to the output terminal, pay attention not to connect the positive and negative terminals reversely.5. This product is a DC buck power supply. The maximum output voltage = input voltage * 0.945.
Features:
1. High Precision and Stability:
The DC buck power supply offers outstanding accuracy with a voltage precision of ±0.5% and a current precision of ±0.5%. This ensures reliable and consistent output, making it suitable for precision applications.
2. Advanced Protection Mechanisms:
Equipped with comprehensive protection features including under-voltage, over-voltage, over-current, over-temperature, and over-power protections. The system ensures safe operation under various conditions by providing adjustable thresholds.
3. User-Friendly Interface:
The unit features a large, easy-to-read 1.8-inch LCD screen that provides clear monitoring of voltage, current, and other parameters. The intuitive interface with 5 buttons allows for easy navigation and adjustment.
4. MPPT Solar Charging Support:
