Transformer lampholders designed to provide an output for a 6 V MES filament lamp which is isolated from the mains supply. This ensures greater safety/longer life than a mains filament lamp and superior illumination to a neon lamp.,These units are designed to be used in conjunction with the 19mm, 19.1mm and 27mm mounting panel Lens/Bezels.

Incorporates a single pole changeover relay and a transformer. Supply voltage 220-240V 50/60Hz.
The remote lamp test facility enables the lamp to be tested without interrupting the normal supply to the transformer, can be initiated via a local or remote push button switch.
Each unit isolates itself from the control circuitry when a test is initiated thereby eliminating any feedback.

A minimum of 30mA per unit is required for the changeover relay to operate the test facility.
