Ground power supply control unit БКHA115B

Purpose


Unit БКНА115В is intended to prevent connection of aerodrome AC power sources having impermissible power quality to the aircraft onboard mains and disconnect such sources in the event of electric power quality going beyond the tolerance limits during operation.

Technical characteristics:

DC supply voltage range

(24,0-29,4) V

Commutation current nominal value

600 A

Current consumption:

DC

1.2 A max.

3-phase AC with nominal voltage of 115 V 400 Hz

0.2 А max.

The unit supports the following types of onboard mains protection:

against connection of source with voltage in any phase below (108-114) V, and against undervoltage in any phase down to (101-107) V with dwell time of (6.0 ±0.9) s;

against connection of source with voltage in any phase above (123-129) V, and against overvoltage in any phase above (123-129) V;

Duty

continuous

Weight

3 kg max.
