JY Voltage, AC current, voltage, frequency, power factor, phase sequence, power, synchronous indication and other non-electrical measurement.

two, The main technical parameters

JY Series pointer instrument: AC-DC voltmeter and ammeter to 1.5 or 2.5, power meter for the 2.5, the frequency table is 2.5, power factor meter for the 2.5 level.
JY series base made of flame retardant TBT plastic, Vicat temperature 130 ℃.

JY Series front panel protection level of conventional IP40, the above can be customized protection class IP52, IP54, IP56, IP65.

JY-45, JY-50, JY-60, JY-670, JY-72, JY-80, JY-96, JY120 instrument insulation withstand voltage test frequency of 50Hz, creepage distance of 6.3mm, 2500V for 1 minute All requirements are in accordance with IEC61010-1.

Overload multiples of conventional 1 times and 2 times the overload factor can be customized by the user requirements 1 times, 2 times, 3 times, etc. Its role is to indicate the instantaneous value of the approximate value of overload current, such as starting the motor starting current.

Third, the advantages of the product (replaceable dial) aspects:

Open the sealing strip, insert or remove the dial.Acurrent meter as long as the transformer secondary current is the same, you can replace the dial, replace, the accuracy of the same;
DC ammeter as long as the shunt output of the same electrical signal or the same instrument input signal, different specifications can replace the dial, the replacement, the accuracy of the same.
