It supports PD3.0/2.0, BC1.2 and other boost fast charging protocols. It also supports the automatic detection of VCONN and analog E-Mark chips, with a maximum power of 100W. It also has features such as built-in PD communication module output voltage detection, over-temperature protection and over-voltage protection.

Eliminate the Power Quality Issues 5 years 29 weeks ago

Power quality is frequently characterized as the electrical network’s or the framework’s capacity to supply a perfect and stable power supply. As such, power quality preferably makes a flawless power supply that is constantly accessible, has an unadulterated commotion free sinusoidal wave shape, and is dependable inside voltage and recurrence resiliencies. In this article we will discuss more about Eliminate the Power Quality Issues.

Inverters / electriccarpartscompany 7 years 14 weeks ago

An inverter, or power inverter is an electronic device or circuitry that changes direct current (DC) to alternating current (AC). The input voltage, output voltage and frequency, and overall powerhandling depend on the design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source. A power inverter can be entirely electronic or may be a combination of mechanical effects (such as a rotary apparatus) and electronic circuitry.

Power factor control (APFC) relays 5 years 46 weeks ago

Power factor control relays play perhaps one of the most important and at the same time, one of the most difficult roles in places where high and controlled amount of electricity is applicable. This includes large factories or schools or colleges. Power factor control relays especially are necessary for colleges because the students are educated on the basis of the various types of voltage and ampere fluctuations in practical labs. However, all relays cannot be said to be accurate and, therefore, there is a need of a very accurate and precise control relay.

Inverter Circuit Diagram 6 years 46 weeks ago

UPS is quite handy especially when power goes off. A UPS converts DC voltage to AC voltage. So, UPS takes DC power of battery as input and gives AC power as output. Here is a step by step tutorial to design a 100 watt 12v DC to 220v AC inverter. This Circuit is simple and very useful, you only need few resistors, capacitors, diode and a transformer.
