Critical Infrastructure
Protection, identification and management of electrical power risks are of primary concern to any company associated with critical infrastructure. Any point of single failure brings about large consequences at the operational level. Securing essential services is a unique challenge for organisations responsible for operational continuity.
Hospitals, Water Treatment, Emergency Services, Hotels, Banking and Finance, Malls, Airports, Public service buildings all depend on electricity for basic needs such as food, water, shelter, communication, employment and healthcare. In any of these there are many critical situations. For example, an extended interruption of telephone and communications services during a major disaster, whether it is a terrorist attack or a natural disaster, may put lives in danger if the public is unable to call emergency services, or if other emergency communications are disrupted.
This is not the place to save money on providing quality power with back up, these industries need top quality products with fail safe systems.

Case Study
Redundant Battery Charging System for runway lighting
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.
Case Study
Auckland Harbour Bridge ‘Train’ Project
Helios Power Solutions were enlisted to design, manufacture and supply the boost chargers, used for charging the electric train that is used in the maintenance of the Auckland Harbour Bridge.

Helios Power Solutions supplied the 750-boost charger (smart charging systems) that powers the train.
