A DC voltage divider R3027/1 (hereinafter - VD) is designed to expand the limits of measurements of electrical devices in DC, and for testing voltage dividers. Accuracy class: 0.0002.
DC Voltage Divider P3027-1 designed for areas with tropical climate, should be marked as R3027-1 4.1*.
The voltage divider R3027/1, is designed for operation under the conditions shown in Table1. Nominal values of the coefficients of division and the corresponding values of the input resistance and input voltage corresponds to those indicated in the Table2. Value of the output resistance of the divider for all of the coefficients - (1000 ± 3) ohm.
DC voltage divider P3027/1 has a specialoption of offline verification and adjustment of thedivision coefficients. The main measuring resistance of VD are placed in the active thermostat. Time required to establish the temperature in the thermostat does not exceed 2 hours.Duration of continuous operation of VD is not less than 8 hours, not including time of the operating mode establishment.
Acceptable basic error R3027/1, is shown in percentage of the nominal values of division coefficient and in working mode is equal ± 0,0002%. Inspection and adjustment of the division coefficients must be held each 2 days in order to provide accuracy in normal condition.
Admissible additional accuracy caused by ambient air temperature change within the limits of operating temperature for every 5°С does not exceed half the limit of acceptable basic accuracy.
Admissible additional accuracy caused by its own heating, passing through the VD circuit does not exceed half the limit of acceptable basic accuracy for normal conditions of use.
Insulation resistance of the VD a DC voltage divider R3027/1 100-200V equal to the values given in Table 3.
Isolation of VD in the working conditions can withstand effect of the test voltage alternating current with the 50 Hz frequency for 1 minute, the value of which corresponds to those indicated in Table 3.VD R3027/1 Power supply: AC voltage (220 ± 22), frequency (50 ± 1) Hz and (60 ± 1,2) Hz. The power consumed does not exceed 30V•A. Dimensions of VD not more than 440x160x460 mm. Weight not more than 11 kg.
Notie: t - the temperature at which R3027-1 was rigged.
A. For all measurements CALIBRATION switch must be turned off and the switch DIMENSION should be in one of the operating positions.
B. The power switch must be turned off
