Galooli supports a variety of DC meters and Current Transformer Rings according to the changing needs of the users, different currents and voltages, and the diameter of the DC cables.
The meters can include an entry for the DC cable or meters that require the use of Current Transformer Rings.
Current Transformer Rings can be used with cables of varying diameters, some of which have an open and close mechanism.

How accurate are the DC Meter and the DC ring?
Item Codes/Data | Meter | Ring | Accuracy | |||
|---|---|---|---|---|---|---|
Galooli Item Code | Voltage reading | Current reading | CT | Overall voltage | *Overall current | *Overall kwh |
CE Transducer NDC (6 Channel) (Meter) | 0.50% | 2.00% | 2.00% | 0.50% | 2.00% | 2.50% |
DC Current Ring (Ring) | 0.50% | 2.00% | 2.00% | 0.50% | 2.00% | 2.50% |
CE Transducer CE11 (Ring) | 0.20% | 1.00% |
| 1.20% | ||
CE Transducer CE11 High (Ring) | 0.20% | 1.00% | 1.20% | |||
*Overall current accuracy = Meter current reading accuracy + CT Accuracy
*Overall kwh accuracy = Overall voltage accuracy + Overall current accuracy
