Aggregate Y300 is designed for AC and DC ammeters and voltmeters verification in a way of comparison of verificated devices with readings of exemplary devices in accuracy classes of 0.2 and less.
Aggregate Y300 is designed to operate in temperature range of 10 to 35 ° C (with relative humidity up to 80%, at ambient temperature of 25 ° C)
Aggregate Y300, designed for export to countries with tropical climates, should work in air-conditioned rooms with mentioned above temperature ranges, and should be marked asY300T4.1.
Nominal value of output voltage, currents and variable effective component value correspond to values shown in table.
Maximum value of each voltage regulation at rated load exceeds value shown in table, for not less than 5%.
Aggregates power is consumed by AC voltage 220V, with frequency 50Hz. Aggregate Y300 can be powered by AC voltage 220 ± 22V, in high-frequency up to 500 Hz. Total Harmonic Distortion of output alternating voltages does not exceed 2%.
Output voltage changes caused by changes in voltage supply ± 10% from nominal value, do not exceed ± 1% of final value limit. Y300 Aggregates power consumption does not exceed 750VA.
Relay semiconductor high-power block anti overload protection is used in aggregates Y300 . Insulation between electrical circuits and the case installation can withstand for 1 minute without breakdown action of test voltage and sinusoidal frequency of 50 Hz:
1.5 kV - for electrically connected between all contacts of mounting pad block switching unit;
3 kV - for electrically connected between output clamps "Exemplary" and "Verifiable" (switch "Power Supply" should be set to "High Voltage").
Devices of smooth voltage output adjustment provide smooth, necessary for using of exemplary device class 0.2.
Aggregate Y300 is equipped with remote divider which division error coefficient does not exceed ± 20%.
Continuous operation time without turning off is not less than 8 hours. Aggregate allows continuous operation at fixed position in verifying control for not more than 4 hours. In mechanical influences resistance aggregate Y300 belongs to ordinary, according to GOST 1845 - 59. Dimensions do not exceeding 520x1040x720 mm, with a removable table - not more than 980x1040x720 mm. Weight without package - not less than 200 kg.
