Voltage sensor designed for measuring voltage of three phases of 230V AC network. It is built on the basis of the ZMPT101B measuring transformer with an operational amplifier. The module is supplied with 5V voltage and has also analogue outputs which should be connected to lan controller inputs to be able to read voltage values.
| Technical parameters | |
| Voltage measurement range | 0÷450 V |
| Maximum current drawn from the voltage source | <1 mA |
| Non-linearity | ≤0.2% |
| Power supply | from the Controller's Lan - 5 V |
| Breakout voltage (insulation) | 4000 V |
| Connecting cable length | 20 cm |
The wires on which we want to measure the voltage should be connected to the connector with screw terminals.
