Good quality LiFePO4 batteries can easily last for over 5000 cycles. This value is calculated at 80% Depth of Discharge. ‘Good quality’ is the main keyword here, as the cycle life can vary significantly between manufacturers. NASN Lithium batteries come with a 5-year warranty, last for a minimum of Read More

The direct current (DC) produced by a half wave rectifier is not a pure DC but a pulsating DC. In the output pulsating DC signal, we find ripples. These ripples in the output DC signal can be reduced by using filters such capacitors and inductors.In order to measure how much ripples are there in the Read More

A rectifier is nothing but a simple diode or group of diodes which converts the Alternating Current (AC) into Direct Current (DC).We know that a diode allows electric current in one direction and blocks electric current in another direction. We are using this principle to construct various types of Read More

We know that a transformer is always rated in kVA. Below are the two simple formulas which can be used to find and calculate the rating of Single Phase and Three Phase Transformers. Read More

A rectifier transforms alternating current (AC) into direct current (DC). Its normal function is charging batteries and keeping them in optimum conditions while, at the same time, providing DC power for other loads. Consequently, it’s essential that the unit takes into account what kind of batteries Read More

A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. Read More

It is partly a matter of convention and standards, and partly because positive earth encourages galvanic corrosion* of the surrounding bodywork - whearas with negative earth is is the much-easier-to-replace electrical contacts that corrode. Read More

Wireless communications sites and network devices typically operate on 12, 24 or 48 volts DC. For 12 and 24 volt sites, the polarity of these devices is typically either +12 volts DC or +24 volts DC. This is also often referred to as negative ground, i.e. the negative line is used as the ground – al Read More
