<p>PURPOSE:To sense whether the installed lamp is a rated one and allow the applicable apparatus to be used safely according to the result from sensing. CONSTITUTION:A falied load current is sensed by a resistance 7. The output of an input voltage change sensing rectifier/smoother circuit 18 is supplied to resistances 8, 9 in series connection. The sensing output of the resistance 7 and the sensing outputs of the resistances 8, 9 are supplied to an input change correcting amplifier 15.</p> |
