Electromagnetic interference is perhaps the most common, yet no less dangerous threat to your electronic devices. By getting a DC noise filter, you're keeping this threat to a minimum. Purchase one of the AEPS ones to be on the safe side – their quality speaks for itself.

 

Buying a power filter – the best thing to do in terms of protecting your equipment from electrical noise hazard. Do so here! Our filters will not disappoint.

DC Noise Filters Are Often a Necessity

If you're operating a particularly sensitive equipment, or even if you're operating a relatively resilient equipment in less than optimal conditions, getting a filter is more a necessity than a luxury.

Even though the majority of electronic equipment does have some kind of filtering device built in already, adding an extra filter to be safe is far from a bad idea. Consider that the built-in filters are typically tested in laboratory settings which do not always translate well into real-life uses. Therefore, having an additional filter to fall back on will ensure your equipment stays functional at all times and abides by all the EMI regulations.

DC Line Noise Filters

If you're operating equipment in DC networks, then our JETDF model filters are made precisely for you. You can combine these with basically any off-shell devices there are, but if you hope to achieve the best effect, coupling them together with our DC/DC converters is advisable (though optional).

In terms of insertion loss, our JETAF filters can offer the following:

Frequency range

Insertion loss

0.15-0.3 MHz

≥15 dB

0.3-1 MHz

≥35 dB

1-10 MHz

≥55 dB

10-30 MHz

≥50 dB

Maximise the safety and performance capabilities of your DC network equipment by getting a reliable filter!

Besides DC Power Filters, You Can Find the AC Ones

Naturally, our offer of filter devices would not be complete if we omitted those designed for AC networks. If you run your equipment on alternating current, which is the standard current in commercial power supply, then the JETAF filter is what you need.

Suited for analog and digital equipment both, the JETAF models offer great protection against surges and other noises travelling along the power line. Their amorphous nanocrystal line cores ensure better filtering and better thermal management, making these devices a good fit for operating in arctic, desert and other environments with extreme temperatures.

And as we always suggest, try pairing these filters with our AC/DC power supplies for the greatest efficiency.

The majority of our AC filters (JETAF 1, 5, 10 and 20) are suited for single-phase AC systems and share the same insertion loss properties:

Frequency range

Insertion loss

0.15-0.3 MHz

≥20dB

0.3-1 MHz

≥35 dB

1-10 MHz

≥55 dB

10-30 MHz

≥50 dB

If you're using AC 3-phase networks, then the JETAF 15-400 filter type is what you need. The insertion loss of this type of filter is as follows:

Frequency range

Insertion loss

0.15-0.3 MHz

≥55 dB

0.3-1 MHz

≥60 dB

1-10 MHz

≥30 dB

10-30 MHz

≥20 dB

Abide by electromagnetic compatibility requirements - buy a filter that improves the noise resistance capabilities of your equipment.

What Is the Surge Protector Filter Up Against?

There are many types of electromagnetic interference that can be categorised according to different criteria.

By origin, we can divide the noise into either man-made or natural. Man-made EMI can originate in other devices in the circuit or in the circuit itself (switching in switch-mode power supplies tends to be the usual culprit).

Natural EMI, on the other hand, results for example from bad weather (lightning strikes) or cosmic noise (solar flares). Noise can also be categorised by its duration (continuous or impulse) or its bandwidth (narrowband or broadband).

However, the most important distinction when talking about the noise filters is whether the interference is conducted or radiated.

Power line filters typically shield your device from noise travelling through the power lines – meaning from the conducted noise. Their protection capabilities against radiated noise coming from the outside are limited. Therefore, you should also pay attention to the right shielding for your equipment!
