Description:This power is of high efficiency and high precision dc regulated power supply, wide input voltage range and output over-current, over-voltage protection function, is suitable for wireless transmitter (intercom) with the car. High quality fireproof board is adopted for power circuit board.Features:1. Smart size, light and compatible, lower noise and no pollution. You can enjoy the perfect car ride.2. High efficiency and high precision, dc output stability precision coefficient less than 1%.3. wide input voltage range, the internal circuit board adopts high quality fire prevention board.4. Automatic overvoltage protection. If the output voltage is higher than the normal output voltage (24V), the power output will be automatically cut off to ensure the safety of your radio station.5. Automatic overcurrent protection. If the output current is greater than the maximum or the load is short-circuited, the power output will be automatically cut off to ensure that your power will not burn out.Specifications:Type: Power SupplyMaterial: MetalInput Voltage: DC18V - 40VOutput Voltage: DC13.8V 0.2VOutput Current: 45APrimary Effect: 2x10-3Load Effect: 2x10-3Output Ripple Voltage: 150 mVP-PEfficiency: 80%Output Overvoltage Protection: 16V 1.5VOutput Overcurrent Protection: 11A 1A (self-recovery)Volume: Approx. 17 * 16.5 * 5.8 cm / 6.7 * 6.5 * 2.3 inch (manual measurement error)Weight: 802g (manual measurement error)Package Include:1 x Power Supply
