Features: The power filter is a reactive low-pass filter installed at the power input of electronic devices, for stable electronic performances. It can suppress noise transmitted through power cables and suppress high-frequency interferences signal generated by electronic devices themselves. High quality imported components with obvious filtering effect. Advanced 25A Filter with two stage low pass design, is a component that must be installed in electronic devices. Widely used in precised measuring instrument, building automation, precised mechanical equipment, elevators, automation systems, servo system frequency conversion equipment, frequency conversion equipment, lighting equipment, etc. Specifications: Material: ABS+Metal Size: approx. 98x28mm/3.85x1.10inch Module filtering category: Two level filtering Module current: 25A Package Includes: 1 Piece Power Supply Filter note: The selection of filters should consider their operating voltages, operating current, and bear voltages. Filter should be installed at the power inlet to reduce radiation interferences. It is best to choose twist pair cables as filter connection cables, which can eliminate some high-frequency interferences signal. The input and output cables of filters must not be parallel and should be kept at a certain distance to ensure the functionality of filter. The shell of the E-point and filter need have good contact and connection to the ground wire.
