Solid-state Controls systems differ from off-line designs in the following ways:
1. Solid-state Controls offers an on-line, double conversion UPS system. Therefore, the client’s critical load is being powered continuously from the inverter. The battery is always being floated by the fully-rated rectifier/charger and is always connected to the inverter input. As result, all components used in the Solid-state Controls design are fully rated to carry 120% of the load on a continuous basis over a 20-year life.
2. Solid-state Controls’ Ferro resonant design has a built in capacity to supply nonlinear (crest factor) loads of up to 3:1 without oversizing.
3. Solid-state Controls’ on-line UPS design is provided with a make-before-break static switch to aid in downstream fault clearing and to protect against possible system failures.
4. Solid-state Controls’ on-line UPS system is a double conversion type, converts AC to DC and then reconverts DC back to AC. It is also insensitive to frequency deviations at the primary input.
5. Solid-state Controls’ on-line UPS system is designed to handle input voltage deviations of +10% to 15% without causing the battery system to take over the inverter’s load. This reduces the UPS systems reliance on its battery, thereby increasing the life of the battery system.
