The Sonel AHV-3 adapter for measuring DC voltage up to 3000V


The changing world of industry is posing new challenges to electricians, which not only requires a different approach than what was needed before, but also a completely new range of measuring equipment. This change is best seen in the electro mobility and renewable energy sectors of the economy, where the voltage of 1000V DC has long been exceeded.

To help solve these measurement problems, Sonel has developed its own high-voltage adapter, the Sonel AHV-3, which allows for the safe measurement of DC voltages up to 3000V (3kV). For safe operation of the probes, the ability to measure is not enough in itself, it is also important to protect the user from an electric shock. For Sonel, this is always at the heart of their meter development. That is why the Sonel AHV-3 adapter has a record breaking CAT III 3000V DC measurement category in accordance with IEC 61010-1. This makes the Sonel AHV-3 the worlds first such safe voltage adapter for use when measuring with multimeters or clamp meters.

Adapter for photovoltaic and electric vehicle charging stations

High voltages are encountered in solar photovoltaic installations, where they can reach up to 1500V DC. We must remember that, according to IEC 61010-1 or IEC 61730-1, that the test meter should have a measurement category of at least CAT III. There us also an analogous situation with EVSE vehicle charging stations. These stations are treated as permanent electrical equipment, so they should also be CAT III category.

The achieved safety level of the Sonel AHV-3 allows us to use the adapter in accordance with CAT IV up to 2000V DC. For example, the adapter can be used without any problem in overhead catenary networks with this voltage, and wherever in the a location where there are special installations with voltage below the measuring category of the adapter.

Full compatibility with the Sonel CMP-1015-PV clamp meter

The Sonel AHV-3 is designed for use with the Sonel CMP-1015-PV clamp meter. Thanks to a special holder allowing the adapter to be mounted on the measuring jaws of the clamp meter. This arrangement allows for measurements to be made much more conveniently and operation much simpler. In addition, the Sonel CMP-1015-PV has a special HVDC function where the results from the adapter are automatically converted into the actual voltage on the object under test. Combined with the clamp meters built-in recorder and mobile application, we get an unprecedentedly versatile measuring device which will meet the expectations of even the most demanding users.

Use the Sonel AHV-3 with other measurement devices

The Sonel AHV-3 adapter also works with other clamp meters, for example the Sonel CMP-200F AC fork meter and Sonel CMP-3000. The AHV-3 can also be connected to ordinary multimeters that are compatible with its measurement technology, such as the Sonel CMM-40 industrial multimeter. Using these meters the measurement result has to be corrected independently for the user by a correction factor, but this allows you to use the devices you already have for measurements above 1000V DC.
