Supply and installation
We work with established UPS and battery manufacturers and can design the arrangement around load, autonomy, redundancy, maintenance access and future expansion.
4ON CRITICAL INFRASTRUCTURE
UPS Installation
A UPS protects critical equipment when the normal supply fails or becomes unstable. 4ON supplies, installs, tests and supports UPS systems from small technical installations through to major critical power schemes.
Round the clock support
A dedicated UK support route is available at all times for faults and urgent incidents, helping to restore service quickly when a UPS system is not behaving as expected.
Battery replacement
Battery life depends on temperature, cycling and operating conditions. We can assess condition, recommend replacement strategies and supply batteries from recognised manufacturers.
Battery testing
Testing can include resistance and impedance checks, data logging, thermal inspection and discharge testing. The objective is to identify weak cells, poor connections and loss of useful autonomy before they cause an outage.
Load bank testing
A controlled load test proves that the UPS and battery system can support the real duty expected during a failure. It is especially useful after load growth, battery work or major maintenance.
Capacity range
We support systems from modest kilovolt ampere ratings through to multi megavolt ampere installations, including temporary and containerised solutions.
