AC DC Converters, such as the NES-100-9, are used to convert AC power into DC power. The NES-100-9 is a high-efficiency, full-bridge power converter with integrated dc-dc input and output filters, power factor correction, and over-voltage, over-current, and over-temperature protection.

The NES-100-9 has a nominal AC input voltage range from 140V to 264V, and can handle a wide range of AC input voltages. The unit can be either openframe or enclosed, and is available in three different power configurations -100W, 200W, and 300W. The AC voltage is rectified by a full-bridge diode rectifier and filtered by an EMI filter and then is filtered again by a DC-DC smoothing circuit. The rectified and filtered AC voltage is then regulated by a seventh-generation adaptive pulse-width modulation (APPWM) and auxiliary pulse-width modulation (APWM) main controller.

The main controller is responsible for regulating the output voltage of the NES-100-9. The controller works by constantly monitoring and controlling the output of the converter. During its operation, the controller adjusts the frequency and pulse width modulation (PWM) duty cycle of the switch devices in order to maintain a constant output voltage. This is done by using several feedback loops that monitor the output voltage, current, frequency, and temperature of the converter and adjust the duty cycle and PWM frequency.

The output voltage of the NES-100-9 is adjustable from 24V to 54V. The unit is designed to operate in a temperature range of -30°C to +60°C with a maximum efficiency of 92% and has good EMI and ESD protection. The NES-100-9 is CE and FCC compliant, and has a built-in overtemperature protection for both the input and output sides of the converter.

The NES-100-9 is a reliable and cost-effective solution for applications that require a high efficiency AC-DC converter. It can be used in industrial, automotive, telecommunications, instrumentation, and consumer electronics. In addition, the unit is designed to meet the requirements of Mil-STD-810F, EN61000-3-4, and EN50121-3-2 standards, making it suitable for a wide range of applications.
