Solar 6220-4A

Overview

The 6220-4 by Solar Electronics audio isolation transformer allows testing for DO-160 Sec 18,sec 20.The transformer is capable of handing up to 200 W of audio power into its primary over the frequency range 30 Hz to 250 kHz. The turns ratio provides a two-to-one step down to the special secondary winding. The secondary will handle up to 50 A of AC or DC without saturating the transformer.

Another secondary winding is connected to a pair of binding posts suitable for connecting to AC voltmeter as directed by the applicable EMI specifications. The transformer may be used as a 4 Ω primary and 1 Ω secondary or 2.4 Ω primary and 0.6 Ω secondary or 2 Ω primary and 0.5 Ω secondary.
