Product Name: Standard Power Monitoring Instrument

Function description:

1. Direct AC sampling based on 16 bit microcontroller;

2. It has many advantages such as complete functionality, economic practicality, high reliability, and strong anti-interference ability;

3. Adopting a separate measurement body and display module for easy installation;

4. RS-485 communication port with optoelectronic isolation, RS-485 is a two-wire local area network;

5. Each loop can connect 32 instruments;

6. The communication rate is 300-19200 baud;

7. The open master/slave serial communication protocol (compatible with MODBUS protocol) enables it to form an efficient and economical power monitoring network with CAM series monitors and other monitoring units;

8. It can be widely used in industrial and commercial distribution panels, switchgear, and various automation systems.

The CAM3300 can be set to Y, Δ and other wire systems through the facial mask button or the upper computer without changing the terminal wiring. The following are the standard measurement values of the CAM3300:

The CAM3300 has simple wiring and can be directly connected to a current transformer without the need for a transmitter. For 4-wire Y systems below 347/600V, no voltage transformer is required.

All internal parameters of CAM3300, such as voltage, current range, voltage mode (Y, △), baud rate, password, etc., can be set by panel buttons or remotely set by a computer through a communication port. The set parameters and measurement data will not be lost for ten years after power failure, and the parameter settings have password protection.
