single phase power meter ac

JBH color single phase power meter

This single-phase AC power meter, in addition to displaying the parameters of voltage, current, power consumption, power factor (cosine phi), temperature, operating hours and energy consumption with very high accuracy, is also able to store energy consumption in the form of KWh. In the event of a power outage, the energy consumed in KWh is stored and not deleted. In addition to single-phase power meters, JBH also offers three-phase power meters.

 

AC display type single phase power meter

In addition to displaying the parameters of voltage, current, power consumption and energy consumption with very high accuracy, the single-phase power meter with AC display is able to store energy consumption in KWh. In case of power failure, the consumed energy (KWh) is stored and will not be reset. In addition, the user is able to define the upper power limit so that if the device consumes more than the set value, the device will indicate an error by flashing the backlight.

Application of single-phase AC display type power meter

• Home fuse box: as a digital meter for constant monitoring of voltage, current, instantaneous power and energy consumption, or so to speak, the same kilowatt hours consumed by residential, commercial and office units.
  Distribution board of residential and commercial complexes: In many commercial, residential and administrative centers where the units do not have independent electricity branches, one of the challenges is to calculate the electricity consumption of each unit. In fact, this product plays the role of a resettable digital meter with the utmost precision.
  Single-phase switchboard: as a digital meter for constant monitoring of voltage, current, instantaneous power and energy consumption, or the same as the kilowatt-hour consumption of the switchboard.
  Industrial equipment and machinery: as a meter for constant monitoring of voltage, current, instantaneous power and energy consumption or so called the same kilowatt hour consumption of that equipment
  Miner Farms: as a meter for constant monitoring of voltage, current, instantaneous power and energy consumption, or in other words, the same kilowatt hours consumed by each miner or any group of miners that have different owners.

100 amp type

In this type, the 2 upper pins are related to the current transformer or CT connection, and the lower 2 pins are related to powering the power meter itself. Additionally, run that phase wire that feeds your consumers through the current transformer.

20 amp type

In this type, there is no current transformer. The 2 upper legs are related to the direct connection of the consumer and the lower two legs are related to the power meter itself.

How to apply single phase AC display type power meter settings

• Turn the backlight on or off
  Press the settings button momentarily.
  High power limit setting
  Hold the setting button for 5 seconds until SET CLR appears. Release the button as soon as the relevant phrase appears. When the three-digit power number flashes, hold the button and increase the first digit until it reaches your desired value, then release the button and wait for the second digit to flash. After the second digit flashes, set the second digit according to the previous procedure. The third digit can be adjusted in the same way. After setting all the numbers, hold the button for 5 seconds to save the settings until the first screen appears.
  Reset the amount of energy consumed (KWh)
  Hold the setting button for 5 seconds until SET CLR appears. Do not release the button. Release the button when the number corresponding to the energy consumption appears and the light of the device is flashing. Perform the reset operation with a momentary press, and if you skip the reset, hold the button for 5 seconds to return to the first window.

Single phase power meter, Modbus AC type

Modbus AC single-phase power meter provides voltage, current, frequency, cosine phi, power consumption and energy consumption parameters with high accuracy in RS485 platform under MODBUS RTU protocol. In addition, this product is able to store energy consumption in the form of KWh. In case of power failure, the consumed energy (KWh) is stored and will not be reset. It is worth mentioning that the user is able to define the address of the modbus, reset the kilowatt hours and set the upper power limit so that if the power consumption exceeds the set amount, the device will automatically send an alarm bit.

How to apply the settings of single-phase DC display type power meter

1. Turn on or off the backlight

Press the settings button momentarily.

 

2. Adjusting the high and low voltage limits

Hold the setting button for 3 seconds until SET appears. Release the button as soon as the relevant phrase appears. When the three-digit number corresponding to the upper limit flashes, each time you press the button, increase the first digit by one unit to reach your desired value. Then release the button and wait for the second digit to flash. After the second digit flashes, set the second digit according to the previous procedure. The third digit can be adjusted in the same way. After setting all the numbers, wait for the number on the right, which is the lower voltage limit, to blink. Set the lower voltage limit according to the mentioned procedure. To save the settings, hold the button for 5 seconds until the first screen window appears after the word pass is displayed.

3. Resting the amount of energy consumed (KWh)

Hold the settings button for 5 seconds until the word CLR appears. Release the button. When the number related to the consumed energy appears and the light flashes, perform the reset operation with a momentary push and if you skip the reset, hold the button for 5 seconds to return to the first window.

4. Setting the current ranges of 50 and 100 amperes

This setting is for 100 amp type. If you connect a 50 amp shunt, set these settings to 50 A, and if you connect a 100 A shunt, set these settings to 100 A. The way to set it is to hold the button for 7 seconds until the word CURR appears. Then you can set your favorite amp by pressing the button once. Then hold the button for a few seconds until the value is saved and the first screen appears.

5. Setting the single-phase power meter in the fuse box

In case of power failure, the consumed energy (KWh) is stored and will not be reset. It is worth mentioning that the user is able to define the address of the modbus, reset the kilowatt hours and set the upper power limit so that if the power consumption exceeds the set amount, the device will automatically send an alarm bit. The small dimensions and very high accuracy of this product have attracted the attention of the activists in the field of industrial automation.
