Measurement & Control Products

You cannot manage what you cannot measure

Efficiency in a low-voltage network begins with accurate measurement. By supplying, from a single point, a family spanning the astronomical time relay, the multi-channel energy analyser and instrument current transformers, Powals makes every point of your distribution network observable and manageable.

Why Powals?

Single-Point Visibility

The multi-channel architecture gathers every feeder on one screen while cutting device and wiring cost.

Persistent Logging

Outage and power-quality events are stored with time-stamps; fault analysis rests on data.

Photocell-Free Accuracy

The astronomical relay, being sensor-free, creates no maintenance item or point of failure.

Frequently Asked Questions

What does a multi-channel energy analyser do?+

It measures multiple feeders or tenants from a single device, monitoring current, voltage, power and energy data, saving panel space and simplifying energy management.

What is an astronomical time relay?+

A relay that computes sunrise/sunset by location to switch loads such as lighting automatically, saving energy in street and outdoor lighting.
