Finder has unveiled a series of digital energy meters for monitoring and measuring electricity consumption in plant and machinery, heating, ventilation and air conditioning (HVAC) and lighting.

The DIN-rail-mounted 7E Series provides users with a local, high-visibility, seven-digit LCD display of total and partial kilowatt hours consumed, instantaneous power, voltage and current.

For the single-phase metering of currents up to 35A, the 7E.23 model measures 17.5mm in width and is operated by a single control key.

The 70mm-wide, two-control-key 7E.46 and 7E.56 meters serve three-phase applications; the 7E.46 handles currents up to 65A and both day and night tariffs, while the nominal 5A 7E.56 is usable with suitable current transformers for measuring up to 1.5kA.

To support remote energy management via a centralised building management system, these digital meters also provide a pulsed, open-collector interface to the DIN43864 standard.

The three-phase models also provide an error display indicating either missing phase or incorrect current direction.

The 7E Series digital energy meters meet the 1/B accuracy class and protection class II and comply with EN62053-21 and EN50470 norms.

They can be mounted in existing consumer units and protected by a tamper-proof cover with a lead seal, provided as a separate accessory.
