Deskripsi
Power Monitor
Model : CAM3300
Brand : Shenzhen Electronic.Co.Ltd
Note: Three-phase electricity meter based on 16-bit single-chip microcomputer and direct AC sampling
Function Description:
1. Based on 16-bit single-chip microcomputer, direct AC sampling;
2. It has many advantages such as complete functions, economical and practical, high reliability, strong anti-interference ability, etc.
3. The measuring body and display module are separated to facilitate installation;
4. RS-485 communication port with photoelectric isolation, RS-485 is a two-wire LAN;
5. Each loop can connect 32 instruments;
6. 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, switch devices and various automation systems.
The CAM3300 can be set to various wiring systems such as Y and Δ through the mask buttons or the host microcomputer without changing the terminal wiring. The following are the standard measurement values of CAM3300:
| Phase voltage | V a , V b , V c , V average |
| Line voltage | V ab , V bc , V ca , V average |
| Current | I a , I b , I c , I average |
| Total power | KW Total |
| Total electricity | KWH Total |
| Active power | KW a、KW b、KW c、KW total |
| Reactive power | FAILURE a、FAILURE b、FAILURE c、FAILURE总 |
| Apparent power | KVA a、KVA b、KVA c、KVA main |
| Active energy | KWH input , KWH output |
| Reactive energy | KVARH input , KVARH output , KVARH total |
| Apparent power | KVAH Total |
| Power Factor | COSФ a , COSФ b , COSФ c , COSФ total |
| frequency | HZ |
| Note: All the above parameters except electricity have maximum and minimum values | |
CAM3300 has simple wiring, and can be directly connected to current transformers without a transmitter. No voltage transformer is required for 4-wire Y systems below 347/600V.
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 by computer through the communication port. The set parameters and measurement data will not be lost for ten years after power failure, and the parameter settings are password protected.
