    solar pump inverter is really in very good quality and we also prepared some promotional products for exhibition. We are going to make new orders soon. Last year there was only one local agent and this year, there are more than 8. Some of them only sell Veikong!

    It’s very good! LCD options make it much easier to use. That’s the strong point, easy of use. And robust. Great PC software.

    VFD500 output frequency is stable when the others are fluctuating. Also output current is less than others, that’s why output frequency is higher too which can save more energy.

380v Electromagnetic Interference Filter



Product Description

380v Three Phase AC EMI Filter electromagnetic interference filter

EMI Power Line Filter from the LC low-pass passive network components.It uses principles of impedance mismatch,so that by
the attenuation of electromagnetic interference signals.
Filter filtering effect depends on the extent of impedance mismatch,the greater the impedance difference, the better the
filter. For example,to get better results, for low-impedance power supply side, should be accompanied by a high input
impedance of the filter;pairs of high input impedance of the load side, then the filter with low output impedance.

Filter instructions
Consider the selection of the main filter insertion loss,the manufacturer of the given curve (parameters) in general in the
standard 50-system test results are only for reference, but the actual applications are generally not 50 systems, insertion loss will
be some offset.
Filter selected second point to note are: operating voltage, operating current, voltage value, leakage current, dimensions,
installation methods; special requirements and special applications must be described when ordering.
DIN-type security choice of terminals: DIN security terminal has the following features: touch security; internal solid, has great
access to cross-sectional area;in line with European industry standards,than conventional terminals safer and more convenient;
use of DIN terminal of the filter is more in line with European market requirements. Most of the products of SIKES to support the
kinds of terminal mode.

Insertion loss
Insertion loss (IL) is the ratio that filter access port voltage of the circuit before and after, be expressed with the following:
Insertion loss (IL) = 20LgV1/V2
Where: V1- the interference signal voltage before filter access
V2- the interference signal voltage after filter access
Insertion loss test methods are detailed in the CISPR17 requirements. In general, product samples provided on the insertion
loss curve is obtained in the 50Ω system: the assumption on both sides of the output power and load, input impedance is
resistive to 50Ω. As the actual use of the environment in the power side and load side of the impedance vary greatly, so
when you get the actual use of the insertion loss values and the samples of different nominal values of insertion loss.
Therefore, the selection of EMI power filter is the best way to access equipment that it carried out the actual tests
