The ASTHA Offline UPS is a type of UPS that directly supplies the power to the AC load from the AC mains in normal operation and uses an inverter to power the AC load from the DC battery. Since there are two separate lines of supplies, the output supply must be switched between the two sources. Voltage and frequency dependent” UPS in compliance with IEC 62040-3, also referred to as offline, protects against many problems in your network. Under normal conditions it conducts the input current to its outlet. When the power supply fails it switches over to a built in battery to compensate for any variations in the mains supply. Gel battery uses sealed gel technology and is designed for highly-reliable, maintenance-free power for renewable energy applications. Depending on the advantage of gel technology, optimum grid, and plate design, the ASTHA gel battery offers the highest power and reliability for your equipment. The small series batteries are ranged from 0.8AH to 33AH. With stable quality and affordable cost, our small batteries are widely used in Small Size lead acid battery is mainly for electrical appliances, lighting, mini UPS, mini solar system, low power backup, etc. Low initial cost and easy maintenance are good reasons to choose a sealed lead-acid (SLA) battery. ASTHA middle-size series batteries are ranged from 38AH to 260AH. Medium Size lead-acid battery is mainly for lighting systems, UPS, EPS system, solar and power system, backup power, ASTHA  valve-regulated, non-spoilable types constructed with an absorbent glass mat (AGM ) with pasted flat lead-calcium alloy plates. They are designed to provide long, reliable service life without maintenance. The large series batteries are all of 2V voltage and the capacity is from 50AH to 3000AH.

In our daily life we use different types of devices that are required of continuous power supply. These computer, telecommunication equipment or other electrical devices might cause serious business disruption or data loss due to power interruption. UPS (or VFD - Voltage and Frequency Dependent) offer the most basic level of power protection. When mains supply is present, the UPS output is supplied via a built-in EMI/RFI filter which provides the load with protection from spikes and transients by clamping peak voltage to pre-defined levels. When the mains supply fails or fluctuates outside of the UPS's operating window, a relay connects the load to the inverter output (resulting in a 4-8ms transfer time). In normal operation, with mains supply present, both output voltage and frequency will track the input voltage and frequency respectively. As the inverter is switched off when the UPS is operating normally, the term 'Offline' is given to any UPS of this design. The inverter output on Offline UPS is typically a square-wave. Offline UPS are basic models, designed for use in small, non-critical applications that require protection against momentary loss of power.
