1 OPERATIONAL OVERVIEW

1.10 Power Supply Unit (option)

The control unit works directly on 24 VDC or through a Power Supply Unit on AC mains supply (115 or 230 VAC). The power supply unit is type PR-300, supplying 24 VDC power (20 A) to the FS-1570 or type PR-850A, supplying 24 VDC (40 A) to the FS-2570. Both 115/230 VAC and 24 VDC power can be connected simultaneously. In this case, the system normally operates on the AC mains supply and when AC power is lost, the PSU automatically switches to the DC power source.

This power supply arrangement satisfies the GMDSS requirements. The FS-1570/FS-2570 can be operated directly from 24 VDC without a power supply.

OVEN power supply: The crystal oven is always powered even when the Power Switch is OFF, provided the mains switchboard is turned on.

AC and DC power switches

Both AC and DC power switches on the PSU can be always kept on. (These switches are provided to turn off the power supply for maintenance.) The control unit may be turned on or off with the PSU kept on.
