Calendar Electronic Ballast

Calendar Electronic Ballast Source: Hongyuan Time: Thursday, 06 November 2014 start date electronic ballast is limiting the lamp on and produce an instant high-pressure equipment, electronic ballasts, also known as ballast, it is an inductor coil inductance coil when the core nature of the current changes, the coil will cause changes in the magnetic flux, resulting in an induced electromotive force, the opposite direction of its current, thus hindering the current changes. The calendar dedicated electronic ballast is a digital calendar dedicated electronic lamp ballast, according to the shape can be divided into: a drag of a ballast, one with two ballast, circular tube ballast. A drag a ballast means ballast can only connect a lamp, and one with two ballast refers to a ballast to connect two tubes, compared to the former, the latter of usage charges It is more cost effective. The circular tube ballast is ring lamp ballasts on the calendar. The electronic ballast power of size, calendar ballasts can be divided into: 22W, 24W, 28W three types of ballast, the corresponding calendar lamps are: 713mmT4 lamp, 849mmT4 lamp, 1000mmT4 lamps. Part of its ballast operating parameters are as follows: Operating voltage: 220V; Operating frequency: 50Hz; working current: 0.15A; starting current: 0.21A; Power factor: 0.98. Calendar dedicated electronic ballast constituent members in a digital calendar is to provide current limiting and momentary high pressure lamp for the calendar.
