Improper voltage is the one of the greatest causes of failed compressors in three-phase units. We are allowed a 10% deviation over or under the unit nameplate-rated voltage. Most technicians know to ...

The primary purpose of a voltage reference (V REF) is to establish system accuracy. An analog-to-digital converter (ADC), for example, uses a reference voltage to set its full-scale input level. The ...

Voltage Drop – Calculate the maximum circuit distance and minimum conductor size for your required voltage drop Conductor Ampacity – Calculate conductor ampacities for different temperature ratings ...

Welcome to the first in a series of articles focusing on electrical calculation basics. This month, we'll discuss the most fundamental of calculations — those for current (I) and kilowatts (kW). We'll ...

Fire-Lite Alarms, a leading manufacturer of quality life safety systems, has introduced its Lite-Calcs 2.0 software, used for voltage drop calculation. Lite-Calcs 2.0 is a second-generation software ...

Capacitive charge-pump circuits are used in many applications. And though these circuits appear deceptively simple, engineers working on them need a thorough understanding of how they function. By ...

In many industries, including health care, manufacturing, electrical contracting, higher education and corrections, reliable, high-quality transformers are essential for keeping operations running ...

This is a simple means of calculating the required size of the input filter capacitor in a basic power supply, or calculating the peak-to-peak ripple voltage in an existing supply. It works by ...
