There are two kinds of Intelligent Electric Isolation Transducers. One is for single-phase Circuits/systems and another
is for three-phase circuits/systems. The three-phase type has two connections: 3-wires and 4-wires.
|
| Input: |
Voltage, current |
| Output parameter: |
Voltage, current, active and reactive power, power factor, frequency and energy |
| Interface: |
RS-485 or RS-232C |
| Power supply: |
Steady voltage power supply (the code of the type is 1~4) and wide voltage range power supply
(the code of the type is 5~9). The former is called the steady voltage input mode and the latter
is called the wide voltage input mode |
| Isolation Voltage: |
1000V (wide voltage input mode) and 2500V (steady voltage input mode) |
| Accuracy: |
0.5% |
| Advantages: |
Small size, powerful function, strong isolation between voltage/current input and output.
Its ID address can be set and modified by software of monitoring system. |

Applications
It is applicable for electric power lines, automatic monitoring systems of equipments, industrial automatic control
systems, supervising systems of rectifying circuits of telecommunication facilities, electric railway,
intelligent residential district, intelligent buildings, automatic power supply and auto-recording
systems for business mansions, safety monitor systems. It also can be used for the key device of electronic kWh
meters and pre-pay kWh meters.
