WHT590 - Watt-hour Transducer 1CH

Product Diagram

The WHT590 Watt-hour Transducer provides an economical and compact solution to monitoring of single phase AC power consumption applications and is ideal for retrofitting into standard power distribution panels and fuse boxes.

The AC voltage is directly connected for measurement and this also provides power for the internal circuit.

The AC current is measured by using an external current transformer for isolation that is supplied with some models.

Two DC pulse outputs Slow and Fast are provided. The Slow output is scaled to suit maximum power input while the Fast output is generally used to verify module function. Both outputs are visibly indicated by LEDs on the front of the WHT590.



Most drawings are supplied in PDF format. Portable Document Format is used to present documents in a manner independent of application software, hardware, and operating systems.
