ABSTRACT:
A planar transformer having windings on a printed circuit board coupled by a high frequency ferrite core driven by a high frequency operational amplifier based relaxation oscillator controlling a switch for pulsing a primary winding of the transformer at a set frequency. The secondary of the transformer powers a lamp circuit which is isolated from the electrical supply, and a test input is connected in a logic OR arrangement with the electrical supply.
