Lumenon 55w Ac HID Slim Digital Ballast for H1 H3 H4 H7 H10 H11 9005 9006 D2r D2s Universal Fit;

This AC ballast have more function compare with the DC ballast √1 . Operating Voltage Wide voltage range to work properly. In the 16-32V DC voltage, the ballast also can work. √2.Protecting function (1). Overpressure Protection In order to prevent the burning of the bulb when the voltage is too high and allow owners to detect vehicle failure. When the power supply DC voltage exceeds 32V, Ballast would stop working automatically, and the output power of not more than 40W,to protect ballast and HID bulb to from damage. (2).Low-voltage protection In order to prevent the bulb will run out of car battery power, causing the car can not start normally, when the power supply DC voltage is lower than 8V, the ballast automatically stop working to avoid damage. (3).Protection of unloading When the ballast is not connected bulb, in the no-load state, the ballast automatically stop working, to avoid high-voltage injury to the staff. (4).Short-circuit protection When the ballast occur an accident, in a short circuit state, the ballast automatically stop working, to avoid damage. (5). Reverse connection protection When the ballast in the installation, the operator error so that the positive and negative input power supply is reversed, the ballast automatically stop working to ensure that the ballast is not damaged. (6).Performance of Waterproof, dustproof, shockproof √3.Quick Start performance Power input current is standard voltage 12.8V, the current is less than 8.5A, so that the xenon lamp in the start within 1 second, the luminous flux of 30% of the standard brightness, 4 seconds, the luminous flux of 80% of the standard brightness. Specifics: Input voltage：9V-18V Starting current：6.2A Stationary current：4.2A Output power：55W±1W Operating temperature：-40℃+105℃ Specification：4.1x2.7x0.59 inches Weight: 1.38lb
