Application Field

PDM31002ZXM is a kind of single-phase full-wave ZXM filter, which can filter out the common-mode interference of the work power and extend the life-span of equipment. The wide-band filter contains high-frequency components, which can avoid the harm of high-frequency interference signals for the equipment, and scope of application includes:

• Digital control system
• Digital instruments such as scopes
• Servo drive system
• Computer-aided equipment, 3D printer
• PCS, PLC and OA equipment

Working Principle

The basic working principle of ZXM Filter is the utilization of an inductive-capacitance series connection circuit, the use of inductance to balance the high-frequency noise, and the capacitance absorbs the low-frequency noise. The inductance of single-phase full-wave ZXM Filter is composed of two single-phase reactors, and the two reactors of one phase form a full-wave reactor.

The current passing through the full-wave reactor will produce a certain resistance magnetic field, and the interference currents of different phases will add to the resistor in the magnetic field, so as to absorb various kinds of high-frequency interference signals and low-frequency interference signals producing in the power line.

At the same time, due to the presence of inductance, the incoming and outgoing non-linear current at the frequency of power supply is filtered, so as to reduce the current interference to the equipment. In this way, the single-phase full-wave ZXM Filter can achieve the effect of power supply anti-interference and power supply filtering.
