Word Clock Reference Output

This output provides a Word Clock signal for use with downstream components.

AC Power Entry Connector

The AC power input uses a standard IEC type connector. Within the USA and Canada, the ADC1 ships with a power cord. In other locations, a location-specific IEC style power cord may be purchased from a local source (including a local Benchmark dealer).

Fuse Holder

The fuse holder is built into a drawer next to the IEC power connector. The drawer requires two 5 x 20 mm 250 V Slo-Blo®Type fuses. The drawer includes a voltage selection switch with two settings: 110 and 220. Both settings use a 0.5 Amp fuse.

The AC input has a very wide input voltage range and can operate over a frequency range of 50 to 60 Hz. At 110, the ADC1 will operate normally over a range of 95 to 140 VAC. At 220, the ADC1 will operate normally over a range of 190 to 285 VAC.

CAUTION: ALWAYS REPLACE THE FUSES

WITH THE CORRECT SIZE AND TYPE.
