Programmable communication ammeter

Technical characteristics of programmable communication ammeter

• Easy installation:

• Open type CT sensor design, can be installed without power outage.

• Supports DIN Rail or embedded installation, compatible with electrical cabinets.

• Low power consumption and stability:

• Adopting low-power chips and supporting battery power supply (suitable for wireless scenarios).

• Industrial grade components, suitable for a wide temperature range of -40 ℃ to 70 ℃.

• Edge computing capability:

• Local storage of historical data (such as 7-day cyclic storage).

• Support simple logical judgment (such as statistical analysis of the duration of abnormal current).

Programmable communication ammeterPrecautions：

1. The connection method of the ammeter: The ammeter must be connected in series with the electrical appliances in the circuit, and cannot be directly connected to both ends of the power supply to avoid short circuit damage to the ammeter or power supply.

2. Current direction: The current should flow in from the "+" terminal of the ammeter and out from the "-" terminal. If connected in reverse, the pointer will reverse, which may cause the pointer to bend.

3. Current range selection: The measured current intensity must not exceed the range of the ammeter. If necessary, it can be determined whether the current exceeds the limit through touch testing.

4. Safe operation: It is necessary to avoid directly connecting the ammeter to the positive and negative poles of the power supply, as the internal resistance of the ammeter is extremely small. This connection method can easily cause pointer deviation, damage to the ammeter, and even damage to the power supply and wires.

5. Regular inspection and maintenance: Regularly check the connection status and electrical contact of communication equipment, keep the equipment clean and in normal working condition, and replace damaged communication cables or equipment in a timely manner.
