Uninterrupted Power Supply POD uninterrupted power supply (UPS) is also known as a double-conversion UPS - In a Double-conversion uninterrupted power supply; this is the most sophisticated form of power protection for critical loads with a wide range of options including extended run times and at larger KVA sizes parallel and N+1 configuration. The UPS rectifier converts the supply mains AC into DC to charge the batteries and to supply the inverter. When the mains supply input is within a specified window (voltage or frequency) the rectifier converts the supply mains AC into DC to charge the batteries and to supply the inverter. Transients, spikes and electrical noise present on the supply mains are filtered by Electro Magnetic Interference (EMI) and noise filters and/or a transformer (on-line UPS dependent) before they can reach the rectifier and the load. The critical load is continuously supplied with a clean and stable sine wave from the UPS, inverter. Therefore no disruption to the output sine wave occurs. Amplification stage has IGBT technology for pure sine wave output.
Other Advantages An on-line uninterrupted power supply is the most sophisticated type and is generally capable of being paralleled to achieve higher output ratings and configuration from 10kVA and above – PowerONDemond. The products in this range also cater for single or three phase inputs, and single or three phase outputs. The other advantage over a line interactive UPS is that an on-line UPS has a built in automatic bypass. This will transfer the connected loads to the mains supply should the UPS develop a fault condition i.e. its inverter fail or be overloaded. Larger on-line uninterrupted power supplies also include built-in Maintenance bypasses.
Recharge The battery charger will generally recharge the battery to 80% within 8-12 hours to provide sufficient battery autonomy for the next supply failure. Where the battery is extended, additional battery chargers can be added to maintain a reasonable recharge time. Sometimes the battery charger within the UPS is sufficient to recharge any additional battery. An uninterrupted power supply battery charger should also incorporate advanced battery management features such a temperature compensation, deep discharge and over voltage protection.
