A typical but essential application is Emergency Lighting, even more important when we are talking about Airports. Air traffic control, navigation and landing aids.
One of the landing aids, the Approach Lights System (ALS), is designed to guide aircraft approaching a runway under nighttime or other low-visibility conditions.
CAB408 is a charger for the CAB580-MOD-SYS system and consists of a 750W 24VDC boost charger, +P50S/1 and a digital V/I meter in a 3U 19-inch rack. Helios Power Solutions were enlisted by the Runway Lighting Project team to design and supply an automatic duel redundant charging system, used for charging batteries on two generator sets used to power the runway lighting.
A digital V/I meter monitors the output of the charger and the charger has a 32A 1P Output MCB to protect the load. The charger also has a LVD in the form of a relay that is externally controlled by the control unit. A P50S/1 blocking diode in the charger is fed externally from the control unit.
