There are approximately 1.2 billion autos in the world. Thanks to efficient recycling there are likely as many lead-acid car batteries.
Did you know the first lead acid battery came from the workshop of Gaston Planté in 1859? And that it was the first rechargeable battery ever?
Today, we will be discussing Sealed Lead Acid Batteries : the basics and some other information you may find interesting about this technology. A Sealed Lead Acid Battery (SLAB, for short) is made up of plates, lead, and lead oxide solution with a 35% sulfuric acid to 65% water ratio. There are two types of […]
Spintronics is an emerging field of technology, where devices work by manipulating the spin of electrons rather than their charge. The field can bring significant advantages to computer technology, combining higher speeds with lower energy consumption. Spintronic circuits require the ability to control electron spin without interference from electron charge. Scientists at EPFL, […]
The power factor (PF) of a device is a number between zero and one that represents the ratio between the real power in watts and the apparent power in Volt-Ampere (VA). A power supply that has a PF of 1.0 indicates that the voltage and current peak together (the voltage and current sine waves […]
At one time, the Standby-Ferro UPS was the dominant form of UPS in the 3-15kVA range. This design depends on a special saturating transformer that has three power connections. The main power supply comes from AC input, through a transfer switch, then through the transformer and to the output. In the case of a […]
In an online UPS, the batteries are always connected to the inverter, so it isn’t necessary to have a power transfer switch. When a loss of power occurs, the rectifier just drops out of the circuit and the batteries keep the flow of power steady and unchanged. When the power is restored, the […]
The line-interactive Uninterruptible Power Supply (UPS) provides a seamless and regulated output voltage. When the mains supply is within a preset input voltage or frequency, the output from the UPS is stabilised to within a specific voltage tolerance. This is achieved using voltage regulation known as Automatic Voltage Regulation (AVR), or Buck/Boost. The […]
There is no question you can save as much as 50% on the cost of batteries for your UPS unit if you choose to go with liquidation, clearance or old batteries. But are you really saving money in the long run? Studies show that if you use new batteries, straight from the supplier, […]
UPS, also known as Uninterruptible Power Supply and Uninterruptible Power Source, is an electrical device that can be used as a battery backup whenever the main power source fails. It is commonly used to protect electronic hardware such as computers and telecommunication equipment where power interruption can cause data loss or business disruptions. UPS units […]
