Send Message Request a Quote

The PA19 series digital ammeter is widely used for single-phase, three-phase or multi-phase current measurement in low voltage power distribution system. This product has a programmable transformation ratio, and some excellent functions can be expanded, such as digital input, relay output, analog output, communication function, etc. Meanwhile, a high-light LED or LCD is applied, and the communication protocol is Modbus-RTU.

This digital ammeter has different mounting dimensions, and it can take the place of analog ammeter directly.
