Main Technical data

1 . Normal working voltage: 0.9Un~1.1Un (Un is reference voltage)

2 . Power caisumption: each voltage circuit power consumption is less than 2W( 1OVA)

3 . Starting current: connected through current transformer active : 0.002In, reactive: 0.003In; connected directly: active :0.004In , reactive:0.005In

4 . Creeping:when voltage circuit voltage is 115% Un , current breaks, the active and reactive output test pulse shall be not more than one.

5 . Error range(%): conform to standardds GB/T172 15.321-2008 and GB/T 17882-1999.

6 . Specified working temperature:-10℃~45℃

Utmost working temperature :-25℃~55℃

7 . Relative humidity :25~90%

Main functions

1 . Measurement function: measure active energy and reactive energy

2 . Supplied with three-phase power, any one phase or two phases fail, the accuracy of measurement isn' t affected.

3 . Output interface: active and reactive and passive pulse output interface with optical coupling isolation

4 . Phase failure indication: Three luminescent tubes

indicates the phase failure,they repr esentsA phase, B phase,C phase respectively,some phase faiures, its corres-ponding indicat or lamp goes out.
