Indication Supply Flasher Units - 1973, 1976, 1979 & 1982

When you walk in to a Relay Room you generaly hear the constant clunk of a Flashing Supply Relay, if you don't the chances are it has one of our Electronic Flasher Units.

The ScR Flasher Unit has gone through 4 iterations with the last one being accepted in the BR Catalogue for supply anywhere in the UK although I suspect it was only used on the ScR.

The Mk4 Unit is quite versatile and can operate from 12V, 24V and 50V and can flash the B, N BX or NX supplies.
