Nowadays in some countries load shedding is a big problem like India. And these countries peoples use UPS / Inverter for emergency electric supply to use his electrical equipment’s. For ups inverter we connect the a DC battery which provide us backup. Inverter ups battery connection diagram and it’s connection method is two simple and easy,…
What is Uninterruptible power supply (UPS) UPS is an electrical machine that provides emergency power to appliances for a short duration of time when power supply fails. It does this backup with the aid of internal batteries installed in the UPS.The primary purpose of UPS is for data protection in the effect of sudden power…
Backup Generator or UPS for Your Business? There are few things that are more disruptive to a business than interrupted power supply. Whether your business relies on computers alone or complex machinery, it cannot operate without power. In areas where power failures, blackout or brownouts are common, or where equipment uptime is critical at all times,…
Types of Miniature Circuit Breakers (MCB’s) MCBs are classified into three major types according to their instantaneous tripping currents. They are Type B MCB Type C MCB Type D MCB Type B MCB This type of MCB will trip instantly at a rate of three to five times its rated current. These are normally used…

Generator is the important power supply equipment to generated electricity. Without electricity, we cannot operated machinery, equipment, lighting, computer and others device for our living. For general power supply, power distributor normally used the high capacity of generator to supply the electricity to the consumer. It different size for backup power supply that used for…
Converters and inverters are electrical devices that convert current. Converters convert the voltage of an electric device, usually alternating current (AC) to direct current (DC). On the other hand, inverters convert direct current (DC) to alternating current (AC). Converter Inverter What it is Electrical devices that convert the voltage from alternating current (AC)…
Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power. Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaic cells convert light into an electric current using the photovoltaic…
