Overview
The Solar 6220-1A Audio Isolation Transformer was especially designed for screen room use in making conducted audio frequency susceptibility tests as required by MIL-STD-461/462 and other EMI specifications. It provides a convenient bench model unit with three-way binding posts on primary and output voltmeter leads. Standard 0.75" spacing of binding posts allows use of standard plugs. High current secondary uses 1/4-20 threaded studs.
The transformer may also be used as a pickup device to measure low frequency EMI currents at lower levels than conventional current probes.
