 Three phase digital voltage meters        Product Description           Product Description Product Name: digital display ammeters Country of Origin: China Model: DM96-3U Color:Black   power:  AC 220V Out size: 96*96*80 Hole size: 91*91 N.W: 0.32KG Package Size: 41.5*37*35 Qty/Ctn: 36 Carton Weight: 12.54 Packing: Carton Warranty: 1Years   Usage   DM96-3U Series digital display three-current combined meters are a new generation of programmable economy digital display mounted meters , which are mainly used in the measurement of three-phase current parameter in the three-phase electric circuit . It displays the measured value with three-row nixietube. Feature Adopt SMT product techniques, compact circuit, high reliability; AC sampling, RMS measuring mode, wave distortion doesn't effect the accuracy rate; Display multiply power is programmable and apply to transformer with several specifications. Setting function of digital filtering time Unique method of installation, can complete the installment easily without tool; With performance of intelligent meters, price of common meters, high cost performance.   Technical Parameters

    Panel description                       Key function   Shift key: under the programmable mode, It is used to left shift the cursor on digit.   Up: under the programmable mode, it is used for progressive increase of parameter value;   Enter the programming mode or return to the previous menu;   Set Key: under the programmable mode, instrument prompts to enter the programming password"Loc" by pressing this key.It is used to return to previous menu with not storing parameters.       Display mode display     Under measuring display status, the display window display current value as the following picture shows;  

The left picture shows:  A  phase voltage is UA=380.1V B  phase voltage is UB=380.2V C  phase voltage is UC=380.3V

       Derscipition of Wiring and terminal (Waring :if it is not the same with the wiring schema of the instrument case,please according to the one of instrument case.) 1 Auxiliary power supply(Power): Instruments need an additional auxiliary power supply to work normally, which is AC 220V. 2 Signal Input (INPUT): HI represents"+" port of DC input signal,live wire terminal of AC voltage input signal and inlet wire terminal of AC current input signal. Input voltage should not be higher than the maximum value (AC 600V, or you should consider of using PT an d installing fuse of  1A on voltage input port. While the current is higher than AC 5A, you  should consider of using CT) 4.3.3 Output(OUT):Higher and lower limit alarm contact output port, relay control mode, can control the external alarm executive device through this port(Note: only for the instruments with alarm contact output).     Cautions 1 Please confirm if the power supply, input signal and each terminal wiring of the Meter are correct and reliable before applying the power. 2 The instrument must be preheated for 15 minutes to guarantee the precision of measurement. 3 The instrument should not be rapped, knocked and vibrate excessively and its using environment should meet the technical requirements. 4 The meter has been calibrated according  to the measuring range required by the customer upon order. The user should  check  once again if the measuring range of the meter is fit with the specifications of the transformer or shunt and set the measuring range again if not.       Company Information                     Packaging & Shipping         Our Services
