EVS18-16R7/A

AC DC Converters

EVS18-16R7/A is a low-power AC-DC converter, a switching power supply that converts an AC input voltage to a DC output voltage or current. It is an electronic isolated DC power supply with efficiency of more than 90%. This series of DC-DC converters are used in electronic systems and applications where a low-cost, lightweight, and compact power supply is required.

The EVS18-16R7/A converter is equipped with universal AC input from 85-264VAC with active PFC, isolated DC DC step-down voltage regulator, and output power range from 5W-32W. It also has fast startup transient response, accurate current limiter, protection against input overvoltage, output overvoltage, output overcurrent, overload, short circuit, and over temperature. It is also very reliable and meets all reliability tests and requirements such as thermal shock, vibration, acceleration, ESD, and MTBF.

The working principle of EVS18-16R7/A AC-DC converter is similar to most power supplies of this type with some minor differences. In simple terms, the AC power is first converted to a DC voltage through a rectifier bridge. This DC voltage is then regulated by the internal regulators, and the power factor correction (PFC) is used to improve the input power factor and reduce the input current. After the PFC stage, the DC voltage is passed through an EMI filter, which helps with both electromagnetic interference and electricity safety. Finally, the DC voltage is passed through a DC-DC converter stage and transformed into the desired output voltage or current. There are a few other useful features of the EVS18-16R7/A such as soft start, active current sharing, and droop control.

In conclusion, EVS18-16R7/A AC-DC converter is an reliable and efficient low-power converter that is ideal for power electronic systems. It has a universal AC input with active PF, isolated DC-DC voltage regulator, and output power range from 5W-32W. The working principle of EVS18-16R7/A is that it converts AC power into DC and then regulates the voltage and current with the internal regulators. It also has many additional features such as soft start, active current sharing, and droop control. This makes the EVS18-16R7/A a great choice for your power electronic system applications.
