Deskripsi
Multi-Channel Intelligent Power Inspection Meter
Model : VI118
Brand : Shenzhen Electronic.Co.Ltd
Product Introduction
The VI18 multi-channel intelligent power meter is primarily used in various industrial control and measurement systems. It conveniently measures current, voltage, active power, reactive power, harmonic power, active energy, reactive energy, and other data on AC power lines. A single multi-channel intelligent power meter can simultaneously measure eight current channels and one voltage channel, making it particularly suitable for applications with concentrated power lines. Multi-channel current loop detection reduces system costs and facilitates field wiring. Its fully isolated processing technology significantly improves transmitter performance and enhances system reliability. Its RS-485 bus output technology and MODBUS protocol facilitate programming and system expansion, making it easy to build your own measurement and control system.
Features
- Cyclic measurement of the effective current value of 8 power lines and the effective voltage value of one line.
- Cyclic measurement of active power, reactive power, and harmonic power of 8 power lines
- Circularly record the active energy value and reactive energy value of 8 power lines (these energy values are for reference only)
- Simple twisted pair 485 communication, the communication distance can reach 1000 meters.
- Adopt MODBUS communication protocol.
- Convenient DIN rail installation
- Easy-to-use LCD display interface
Notice:
1. The factory calibration parameters are: module address is 00 (hexadecimal), baud rate is 9600bps.
2. The programming module address can be set arbitrarily from 0-255 (0-FFH);
3. There are five programming baud rates: 1200bps, 2400bps, 4800bps, 9600bps and 19200bps.
4. After the module address and baud rate are modified, their values are stored in EEPROM and will not be lost when power is off.
