About this item
- ENERGY MONITORING – Track the energy consumption of your home or office in real time! This advanced energy monitor measures active energy (kWh) of low-load circuits (45 A rated) with a pulse output.
- EASY-TO-READ DISPLAY – The non-resettable meter is equipped with a 6-digit LCD display (without backlight), showing values in 4 integrals + 1 decimal place. The maximum reading is 99,999.9 kWh. When the reading exceeds 10,000 kWh, the meter displays 5 integrals + 1 decimal place.
- PULSE CONNECTION – Our power meter uses a pulse output isolated from the internal circuit to generate pulses proportional to the measured energy. This requires an external voltage supply of 5–27 V DC with a maximum input current of 27 mA DC.
- ENERGY-SAVING POTENTIAL – The meter features an LED light with a constant of 1000 imp/kWh, which flashes when power is consumed. The more power used, the faster it blinks. This makes it easy to monitor your consumption and save valuable kWh.
- SUB-METERING – This energy monitoring tool provides a detailed breakdown of the energy consumption of a single circuit. Ideal for monitoring individual circuits and for accurate sub-billing through precise measurement and tracking of energy usage.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
