Speed ​​change is the replacement of replacement gears. Insulation between the body and insulated from the electrical circuits of the device (except chain deposition time stamps), and isolation between separate electrical circuits under normal operating conditions is alive withstand for 1 minute. Impact of testing AC voltage frequency (50 ± 1) Hz, RMS value is: 1.5 kW - for ammeters, voltmeters, to be included in current transformers and voltmeters direct connection with finite values ​​ranges 15V, 25V, 50V, 150V, 250V.
Note. Voltmeters for direct connection with end of the measuring range of 500 and 600 V insulation between the body and the measuring chain, and between the measuring circuit and the power to withstand the test voltage 2kV.
The insulation resistance between the case and insulated from any electrical appliance chain in normal conditions of use of at least 40 MΩ.
Overall dimensions shall be 160x160x195 mm. The total overall size of the inverter 160x160x280 mm. Unit weight is not more than 4.6 kg. In accordance with the order of ammeter and voltmeter N393 comes with a record of testimony in ink or ink and ball pivot.
