Critical Infrastructure & Utility Case Studies

Power Utilities DC UPS System installed for 11kV switchgear protection

DC UPS System for 11kV Switchgear Protection

Helios Power Solutions engineered a fully monitored DC UPS system designed for 11kV switchgear protection duty. Delivering 5.5kW output at 110VDC from a 400VAC 3-phase input, the system was supplied to Ravensdown Fertiliser in partnership with ABB New Zealand to maintain uninterruptible protection relay and tripping power.

Rating: 5.5kW | 110VDC Output | 400VAC 3-Phase Input
Transmission Grid Dual Output Controllable Modular Battery Charger System for Transmission Substations

Dual Output Modular Charger for Transmission Substations

A specialized dual-output 21U power system integrating 5.5kW 110VDC and 1.2kW 24VDC modular battery chargers with high-temperature battery banks. Designed for transmission grid substations in New Zealand, featuring complete N+1 modular redundancy, active temperature compensation, and SNMP/DNP3 Ethernet interface.

Configuration: 110VDC (5.5kW) + 24VDC (1.2kW) | N+1 Redundancy
Aviation / Infrastructure Redundant Battery Charging System for Airport Runway Lighting

Redundant Charger System for Airport Runway ALS Lighting

Airfield Approach Lighting Systems (ALS) demand continuous power availability during low-visibility landings. Helios custom-engineered a redundant industrial battery charging setup with instant switchover and fault isolation, ensuring zero operational disruption for airport air traffic control and landing aids.
