Product Introduction: Three-phase digital voltmeter

The three-phase current voltmeter is used to measure the "three-phase current" or "three-phase voltage" in the field.

In modern electronic equipment, current and voltage are very important measurement parameters. When we need to measure current and voltage, we need to use ammeter and voltmeter. In today's digital world, we can use digital ammeter and digital voltmeter, which are also known as voltmeters and ammeters.

Digital ammeter and digital voltmeter display the measured value of current and voltage through digital display. One of the advantages of these instruments is their high accuracy. Digital displays use numbers to represent current and voltage, eliminating the uncertainty caused by human error. Therefore, once you know the system employed by the digital display, you can trust its accuracy without making any manual adjustments.

In addition, digital ammeters and digital voltmeters also have the advantage of easy readability. The digital display displays all the measurements on a screen so you can view them whenever needed. Moreover, since the digital display can be backlight, values can be easily read even in low light environments. This makes digital ammeters and digital voltmeters essential appliances in modern electronic devices.

Scope of application:

Voltmeter Ampere Meter Digital used in control system, energy management system, substation automation, distribution network automation, building automation, industrial automation, residential power monitoring, intelligent buildings, switchgear and so on.

Wiring method:

Voltmeter Ampere Meter Digital: The standard rated input current is 5A, and external CT should be used if the current is greater than 5A. If the CT used is connected to other instruments, the wiring should be connected in series. Before removing the current input connection of the product, it is necessary to disconnect the CT primary circuit or short-circuit the secondary circuit. It is recommended to use the wiring bar, do not directly connect to the CT, so as to facilitate disassembly. Three-phase voltage input: The standard rated voltage is 500V, and the external PT should be used when the voltage is greater than 500V.
