AC DC Converters

The NDR-75-12 is an AC DC converter with a host of impressive features. It is designed to provide an output of 12V DC from an AC input from an appliance outlet. This power converter is ideal for powering a variety of DC devices that require a steady, low voltage DC power supply, such as CPU coolers, medical equipment, and more. It is designed for easy integration into a wide variety of applications.

Overview of Features

The NDR-75-12 is designed with a range of features that make it an ideal solution for most DC voltage requirements. It is designed with a power factor of 0.997 giving it a very efficient power conversion process. The overload current protection is set at 15%, ensuring the unit will not overload even in the most stressful operating conditions. It also has over-voltage and over-temperature protection, making sure it performs optimally in various environmental conditions. The unit is also designed to start up quickly, allowing it to be ready to run within 2 seconds of being turned on. The NDR-75-12 also features a metal casing, giving it more protection for use in harsh environments.

Working Principle

The NDR-75-12 uses a PC (polarity control) power conversion process to create its 12V DC output. The AC power input is converted to DC power using the switching power supply. This is accomplished by controlling the on/off switching of the power supply transformer rapidly with the PC module. This rapid switching of the transformer allows the power supplied to the load to be regulated accurately, creating a steady DC voltage output.

Application Field

The NDR-75-12 is a versatile converter and is suitable for a variety of DC power requirements. It is ideal for powering medical equipment, CPU coolers, computer accessories, smaller electronic systems, and LED lighting. The metal casing makes it suitable for use in harsher environments and the power factor of 0.997 makes it an energy efficient option. The NDR-75-12 is also suitable for automotive applications, allowing it to be used to power additional car electric equipment that require DC power.
