UPS built-in Lead Acid battery. UPS controller daughterboard based on an advanced DSP micro-controller unit. mature true online circuit guarantees perfect reliability.
These batteries are rechargeable deep cycle batteries They are automatically charged and store power when the AC utility power is present, when the AC power break out, the UPS switches to battery back up mode and these batteries discharge to power the output. for the models with External batteries, a larger charger board is configured for the UPS, We can offer separate batteries and battery cabinets and accessories based on your specific back up program.
Real double conversion, microprocessor control can optimize reliability; it can be used even in converter mode, and it is also compatible with the generator(Benefits of uninterruptible power supply). It is an optional SNMP remote control, the comprehensive display can easily monitor and access UPS status.
Line-interactive UPS with LCD display built-in maintenance-free valve-regulated lead-acid battery. The number and capacity of batteries vary by model.
The Line-interactive UPS has a display window that displays the working status of the UPS(1000va line interactive ups), battery mode, AC mains, and fault indicators.
UPS plastic panel, elegant new design. Metal cabinet with vents. The UPS consists of a plastic panel and a solid metal cabinet. It guarantees the safety and durability of the UPS.
Integrated power board controlled by CPU. The EI laminated power transformer is made of brand-new silicon steel and high-quality windings, ensuring high efficiency and strong power supply capacity.
The online interactive UPS system uses automatic voltage regulation to correct abnormal voltage without switching to the battery.
The backup UPS is directly supplied by the mains to the load when the mains power is normal, and when the mains power exceeds its working range or is out of power, it is converted to battery inverter power supply through the transfer switch. The structure is simple, the volume is small, the cost is low, but the input voltage range is narrow, the output voltage is stable and the accuracy is poor, there is a switching time, and the output waveform is generally a square wave.
In applications with unstable power quality, online UPS is usually the preferred solution because it is the only UPS that completely isolates the connected equipment from the original mains by converting the power from AC to DC and then back to AC.
When the mains power is normal, the online UPS is rectified by the mains to provide DC voltage to the inverter, and the inverter provides AC to the load. When the mains is abnormal, the inverter is powered by the battery. It is in working condition to ensure uninterrupted output.
On-line UPS has the following characteristics: it has an extremely wide input voltage range, no switching time, and high output voltage stability and precision, which is especially suitable for occasions with high power requirements.
