Feature: 1. Over current, over voltage, overheating, short circuit and other automatic protection functions, when the protected line into the unsafe value, the built‑in protector will automatically cut off the circuit. 2. As long as the value returned to the normal range and the voltage reducer will return to normal work. Adopt sealing waterproof technology, all‑around protection, more stable and reliable. 3. Silicone sealing with waterproof, dustproof, shock resistant, suitable for all kinds of harsh environment use. 4. Suitable for LED display screen, monitoring camera, electric fan, water pump, motor, photovoltaic energy numerical control equipment, water pumps, LED lamp, digital photo frame, electronic refrigerator. 5. Can be used for portable DVD, audio, security systems, portable tools, printers, all kinds of industrial electrical equipment with corresponding voltage. Specification: Item Type: Voltage Reducer Material: Silicone + Aluminum Model: GYVRM-K481210 Input Voltage Range: 36V48V (DC20-60V) Output Voltage: 12V Rated Output Current: 10A Output Power: 120W Protection Class: IP67 Conversion Efficiency: Up to 96% Operating Temperature: -20℃ ~ + 80℃ Installation Cable Length: Approx. 13cm / 5.1in Note:1. In order to ensure the normal operation of the converter, the input voltage shall not be lower than the minimum or maximum input value limited by the product. The input voltage shall be more than 2V higher than the output voltage value. If there is No voltage difference of 2V, the output value will be lower without damaging (affecting) the use of the converter.2. The input current must be greater than or equal to the power required by the output load device (e.g., the power required by the load device is 100W, so the input power must be greater than or equal to 100W).In the use of the converter, the current of the load device should not be greater than the maximum current value that the converter can withstand. As far as possible, the converter should be left with a margin to ensure the normal operation of the converter to achieve the highest conversion efficiency.3. When using, the positive and negative terminals of the converter should not be connected back, which may cause damage to the converter. It is recommended to add a suitable fuse at the input end when using.4. Without load, the chip works in light load mode, and the output voltage may change within a certain range..
