48*48mm Analog Panel Voltmeter (JY-72)

48*48mm analog panel voltmeter (JY-72)


Uses and applications:
This series of meters is a direct imitation of power measurement display instruments, measuring DC current and voltage, AC current and voltage, frequency, power factor, phase sequence, power, synchronization instructions and other non-power measurements. It has been widely used in a variety of AC and DC transmission and distribution systems, power control panels and other electrical devices, in the industries of maritime shipping, rail transport, chemical flameproof, low voltage equipment, construction equipment, generators, machinery equipment, etc. Being able to make electrical measurement and non-power measurement, it is a high-end instrument applied in general environmental conditions.


The outer casing of the panel meter:
The base of the series of JY meters is made of TBT flame-retardant plastic, and its vicat temperature is 130° C. The outer shell is made of ABS flame-retardant plastic, and its vicat temperature is 85° C.
Changes caused by the temperature:
Temperature range for reference: 23° C± 2° C, 13° C~23° C, and 23° C~33° C. The changes caused by the impact of temperature are not allowed to be out of the range of the level index ± 100%.
The installation:
Unless specified, the meter is usually installed in a vertical position. Other installation positions such as horizontal and inclined position can be installed according to the customer's requirements. The corresponding level of accuracy is only valid to the regulated installation position. The meter has two kinds of instruction angles: Right angle 90° And wide angle 250° .
