AGH204S-4

Product catalog summary

Intended Use
The AGH204S-4 coupling device is designed for use with an ISOMETER® to monitor the insulation of 3AC IT systems (unearthed systems). It extends the nominal voltage range of the ISOMETER® to 3(N)AC 0…1650 V, 50…400 Hz and DC 0…1840 V at terminal AK160, and up to 3(N)AC 0…1300 V, 50…400 Hz at terminal AK80. Any use outside of this is considered improper.

Functional Description
The device extends the nominal voltage range of the ISOMETER® as specified in the technical data.

Standards and Certifications
The AGH204S-4 complies with DIN EN 61800-5-1 (VDE 0160-105-1).
