　　According to the requirements of IEC 60255-26 standard, CNV 508N4 is a special coupling and decoupling network for electronic disturbance testing of measuring relays and protective equipment. It is specified that the 0.5uF capacitance on the wire should double the pulse.

　　Each cable has an inductance greater than 1.5mH to protect auxiliary equipment from being directly connected to the test pulse. In this test, damped oscillating pulses with a frequency of 1 MHz are used as interference signals, generated by the device OCS500N6 or OCS500N6F.
main feature:

　　Selectable for all coupling modes according to IEC 60255-26

　　Remote control via OCS500N6 or OCS500N6F

　　Coupling 0.5uF capacitor

　　Decoupling >1.5mH inductance per line

　　Typical voltage 250V AC/DC

　　Typical current 4A or 16A AC/DC

Standards compliant:

　　IEC 60255-22-1

　　IEC 60255-26

advantage:

　　Fully automatic coupling network for IEC 60255-26

　　Depending on the setup configuration not to be tested, test in differential mode (line-to-line in the same pair) or common mode (one pair grounded or one pair ungrounded and the rest grounded). CNV508N4 selects the required coupling method and the line to be coupled through OCS 500N6 to automatically set. During the test, a maximum of 4 pairs/8 lines can be tested.

　　According to the IEC 60255-26 standard, there are many different ways to test measuring relays and protective equipment under different conditions. Each pair is individually tested differentially. The common mode is suitable for the case where each pair of wires is grounded or one pair of wires is not connected and the rest are grounded.

　　The CNV 508N4 series is a sophisticated CDNs for fully automatic operation, remote control with different coupling methods by OCS 500N6. According to the coupling method tested, this instrument provides the most convenient and reliable operation experience for users. The selected coupling mode and cable are directly displayed by LED lights.

　　complete solution

　　According to IEC 60255-26, the CNV 508N4 series includes the required 1.5mH decoupling inner conductor for auxiliary equipment decoupling, coupling each cable and relay through a 0.5uF capacitor to meet all settings for differential and common mode testing .

　　Control of the coupling mode and the selected test cable via the OCS 500N6
