250APH12L

Power Line Filter Modules are a type of electronic device used to reduce or control noise in an electrical circuit. These are typically used in industrial or medical applications where noise is a concern. The 250APH12L is an example of one such module. This article will discuss the application field and working principle of this module.

The 250APH12L Power Line Filter Module is designed for industrial monitoring, control and automated process applications. It is designed to help reduce interference and noise from external sources such as microwaves, lighting, RF emissions and other signaling devices. The module is a three-phase AC unit with a rated voltage of 250 Vac (±15%) and rated current of 12A. The module provides a wide bandwidth of rejection and typically used in power line systems such as those used in power quality instruments.

The working principle of the 250APH12L Power Line Filter Module is relatively straightforward. The module operates by using inductors and capacitors to minimize power line interference. As AC power passes through the filter, the inductors create a magnetic field which captures the external electromagnetic interference created by other sources. The capacitors then act as filter elements that attenuate any noise that is still present after the inductors have done their job.

The filter module is designed to operate under a wide range of environmental conditions, with an operating temperature range of negative 40 degrees Celsius to 105 degrees Celsius. It also offers a high level of performance, with a minimum differential mode attenuation of 40 dB (at 50 kHz) and common mode attenuation of 30 dB (at 150 kHz).

The 250APH12L Power Line Filter Module is particularly useful in applications where precision is essential. It is also suitable for industrial process automation, robotics and motor control, due to its ability to reduce noise and interference generated by other sources. Additionally, the module can be used in medical, military and aerospace applications, due to its high level of performance.

In conclusion, the 250APH12L Power Line Filter Module is a useful device for reducing noise and interference generated by other sources. It operates by using inductors and capacitors to create a magnetic field which captures external signals, and filter elements to attenuate noise. The module is suitable for industrial process automation, robotics and motor control, as well as medical, military and aerospace applications.
