Model: SD194I-9×4 3 phase AC ammeter
Model: SD194U-9×4 3 phase AC voltmeter
Accuracy: ±0.5%±2 digits
For through current: 1A 2A 3A 4A 5A.
For transformation ratio: The users can set range form 1 to 9999 times (3 phase ratio is changed at the same time). The meters should be used with a current transformer of which the secondary current is 1A or 5A.
Overload rate of ammeters: ①1.2 times
For through voltege: 100V 200V 300V 400V 500V.
For transformation ratio: The users can set range form 1 to 9999 times (3 phase ratio is changed at the same time). The meters should be used with a voltage transformer of which the secondary voltage is 100V.
Overload rate of voltmeters: ①1.2 times
Rated auxiliary power supply: AC220V±10% Frequency 50/60Hz
Product display features:
1.Three phase current
When the show value ＜10A, it will display 3 decimal points, display like X.XXX(A).
When 10A≤value＜100A, it will display 2 decimal points, display like XX.XX(A).
When 100A≤value＜1000A, it will display 1 decimal point, display like XXX.X(A).
When 1000A≤value＜10000A, it will not display any decimal point, display like XXXX(A)
When the value≥10000A, the KA indicator lights, display like XX.XX(kA).
2.Three phase voltage
When the show value ＜1kV, it will display 1 decimal point, display like XXX.X(V).
When 1kV≤value＜10kV, it will not display any decimal point, display like XXXX(V).
When 10KV≤value＜100kV, the kV indicator lights, display like XX.XX(kV).
When 100KV≤value＜1000kV, the kV indicator lights, display like XXX.X(kV).
When the value≥1000kV, the KV indicator lights, display like XXXX(kA).
The meter is easy to install with high-strenghen plastic pieces by pushing so that it is of high immobility.
