3. Voltage signal input via direct connect or PTs

4. Current signal input via CTs or Rogowski Coils

5. Power supplied by 85~265Vac L-N power source

Step ②: Download&Register IoT APP

1. Introduction of IoT Energy Monitoring Solution (IoT EMS)

2. Introduction of IoT EMS APP (for mobile users)

3. Introduction of IoT EMS WEB (for PC users)

4. Download of IoT EMS APP

5. Register your account with 3-month Free Trial

6. Or contact us to get Test Account

Step ③: Add Meters to your Account

1. Meters are recognized by unique SN code

2. Scan QR code to add meter to your account

3. Edit CT&PT ratio according to paired CT&PT

4. If voltage input via direct connect, PT ratio set to 1 (Actual Power System Voltage = Voltage Signal Input of Meter)

5. If current input via 250A/5A CTs for example, CT ratio set to 50 (250÷5=50)

1. After 3 months, host service&buy-out service will be available for account renewal

2. Contact us for more information about system charge item&meter quotation

3. Before we send you the quotation, we will set a solution acoording to your request

4. Provide full technical support for installing meters and connecting meters to our system

Q：What's the biggest advantage of ADW300?

A：ADW300 has its built-in wireless communication module which allow it to realize 4G LTE, WiFi, NB-IoT, LoRa upstream communication without using extra IoT gateways. For the application scenarios when the meters can't be of centralized installation, ADW300 will usually be the best option for monitor 3-phase circuits that were far from each other.

Q：How should I deal with RS485 network communication malfunction?

A：First, check if the wiring of RS485 communication line was loosen or wired incorrectly.(like reversely wiring the A,B terminal).

Next,inspect if the meter’s setting of address, baud rate, check bit was correct by using keypads on the meter.

Q：What if LoRa communication of meters malfunctioned?

A：First, use USB to RS485 serial converter to connect the meter with computer. Then use adjustment software to check if setting of meter is on consensus with the setting of master station.(setting of channel and spreading factor--SF)

If setting remain the same, then it might be due to large interference of work site or the excessively far range between meter and host. In that case, it’s recommended to use chuck antenna or set a new master station nearby.

Q：What’s the difference between ADW300 and ADW300W

A：ADW300 has internal current transformers and can select compatible current transformer according to the site current to realized a secondary connection via CTs.

   ADW300W on the other hand, has external current transformers.(non-detachable or it will damage the meter) This kind of design extremely ease the wiring and installation if the work-site already has CTs.

Q：What do 3×57.7/100V,3×220/380V,3×380/660V,3×100V,3×380V,3×660V represent respectively?

A：The meter’s spec of 3*100V,3*57.7/100V is suitable for high voltage power system while pairing with PT(potential transformer or voltage transformer). Beside, 3*100V represent 3-phase 3-wire and 3*57.7/100V represent 3-phase 4-wire.

The meter’s spec of 3*220/380V,3*380/660V,3*380V,3*660V is suitable for low voltage power system(directly connect with meter). Meanwhile,3*380V,3*660V represent 3-phase 3-wire and 3*220/380V,3*380/660V represent 3-phase 4-wire.
