The 7E Series single phase kWh totalising meters from Finder have beendesigned for the measurement, recording and display of individual energyconsumption for loads drawing up to a maximum of 65A.
The meters are targeted at applications in residential, commercial andindustrial installations where the consumption of energy needs to bemeasured or monitored. This might be either to assist in meeting governmenttargets for reduced emissions by minimising energy consumption, or to allowmetering of locally billed electricity supplies.
Typical areas of use mightinclude test laboratories, the individual monitoring of machines, controlcabinets and switchboards, in battery charging equipment, or for hook-upsupplies to campers, caravans and boats.
The meters can be DIN rail mounted, and can easily be installed in astandard consumer unit. A high resolution pulsed open-collector outputallows accurate remote monitoring.The two models in the series, the 7E.13 and 7E.16, are rated for maximumcurrent levels of 32A and 65A respectively, for a supply voltage of 230V ACat 50Hz.
The display counter features a 4mm high, 7-digit display with a reddecimal digit, giving a maximum totalising count of 999,999.9kWh. Bothmodels have a maximum resolution of 100Wh, and their accuracy is specifiedas Class 1 (±1%).
Rated power is 8VA and the AC operating range is 0.8 1.15 of nominal voltage.The meters are housed in compact industry-standard packages with simpledirect wiring connections.
They are PTB approved in accordance with EN61036, and carry CE type approval for EMC.Model 7E.13 is a single unit width (17.5mm) with the digits arrangedvertically, while 7E.16 is double unit width (35mm) and has a horizontaldigital display.
Both models feature a flashing red LED as a quick visualindication of operational status.
