[ARC5] Relay Unit K-15 (28V): what is it?

[Ken Corwin]

Hello, Roy -

The K-15 is a power relay designed to be fed directly from a LV bus
through a 20A circuit breaker.  It was available for A.R.C. Type 12
(and similar) equipment, where transmitter plate voltages were
supplied by D-10A receiver dynamotors.
