PD19 Series Digital Frequency Meter/Counter

This PD19 series digital frequency meter is able to detect the frequency in a low voltage power distribution system, and it can replace traditional analog frequency meter directly.

Our product is equipped with a high-light LED or LCD, and it follows the communication protocol of Modbus-RTU. Meanwhile, digital input, relay output, analog output, data communication and other functions can also be achieved. Additionally, the transformation ratio is programmable, and there are many installation sizes available for this product.
