Questions And Answers About UPS, Battery, Zener Services

Basic questions

What is a UPS?
Abbreviated as "Uninterruptible Power Supplies" means uninterruptible power supply. An uninterruptible power supply is a device consisting of solid components that is connected between the input power supply and the consumer and prevents the occurrence of input power disturbances, including its complete disconnection. In fact, it is a combination of converters, switches and energy storage (battery) that forms the power system to maintain, maintain and connect the load power in the event of a fault in the input power. In fact, using a backup power supply such as an uninterruptible power supply (UPS) will enable you to overcome most of the city's power problems, as well as protect against total power outages.

Technical questions

What is Line-interactive UPS?
This type of UPS includes devices that have tried to provide better performance than the Offline series by adding a voltage regulation system in the Bypass path. Two of the most common systems in this category are UPS equipped with Buck / Boost transformer and Ferroresonant transformer. Similar to offline models, the Line-interactive model feeds its load through the bypass path and transmits it to the inverter in the event of any accident that causes a power outage in the city. In terms of battery, charger and inverter circuit are similar to the offline system, but due to the addition of voltage regulation circuit in the bypass path, less load is transferred to the inverter. Such a system has a greater impact on reducing costs and longer battery life compared to the Offline series.
