A Din 96mm digital KWh meter with a pulse output for interfacing with BMS systems. The CUBE 300 is suitable for single phase and three phase loads, both 3 wire and 4 wire balanced or unbalanced. The meter is designed to measure accurately all types of loads inductive or resistive and electronically controlled loads. The CUBE 300 benifits from fully isolated current inputs and to aid commissioning the meter can also display instantaneous KW for 60 seconds before reverting back to KWh. A high speed internal RS485 MODBUS communications option allows all readings to be given remotely. Also available is a Dual Tariff option giving two registers, tariff changeover is effected by an external input signal.

NOTE: the CUBE 300 is available in standard execution ie, 400/415V L-L and 230VAC aux supply with 5Amp CT inputs. Non standard input voltages such as 110V L-L and 1Amp CT inputs are only available for large quantities. For smaller quantities please use the KWH CUBE.

A Din 96mm digital KWh meter with pulse output for interfacing with BMS systems. One unit suitable for both single phase and three phase 3 wire or 4 wire loads, balanced or un-balanced. The meter benefits from fully isolated current inputs and to aid commissioning instantaneous KW can be displayed to confirm the load to be measured. The meter not only being in the popular Din 96mm size is only 71mm deep. Utilising the latest backlit display technology affords excellent viewing visibility.

A Din 96mm KWh meter that is designed to compliment standard panel instruments. Available in both single phase, three phase balanced or unbalanced, 3 wire or 4 wire configuration. Also available is a DC KWh meter option, meter type EL96GT. All meters can be supplied with or without volt free relay pulse output, standard pulse rate 1 pulse per KWh (other pulse rates upon request). Front panel LED flashes every 0.1KWh. The counter is a 7 digit mechanical non resettable type.

An explanation of the Measuring Instruments Directive (MID).

MID stands for ˜Measuring Instruments Directive" and is a new European Union directive to create a single market for measuring instruments across the EU and was effective from the 30th October 2006. The aim of the directive is to guarantee to users a standard European level of safety, reliability, tamper proofing and accuracy to instruments. For when meters are subjected to certain minimum specified levels of climatic conditions, mechanical environments and electromagnetic interference. "MID" is a replacement for the old UK "OFGEM" approval, also referred to sometimes as "OFFER" approval. It is advised that all electricity meters must be approved if used in a billing situation. This is a requirement of Schedule 7 of the Electricity Act 1989. Prior to the 30th October 2006 approval would have been granted by OFGEM. However, meters approved under previous UK provisions need not be certified in exempt situations. Usually landlord/tenant contracts, so long as a written agreement exists between the parties to dispense with the certification requirements. But any meter must still be of an approved design and be maintained in good working order. The new MID directive refers to ten categories of measuring instruments of which four relate to utility meters. In particular KWh meters fall within MI-003 ACTIVE ELECTRICAL ENERGY METERS.

The Power Rail 303 is a single function electronic kWh meter. Standard current transformer inputs (CTs) allow connection to loads of a few watts to hundreds of megawatts. Accurate measurements of kWh provide repeatable results required by energy management schemes.

Designed for ease of installation, the Power Rail 303 has quality rising cage terminals which allow repeated use and secure termination of a wide range of cable types and sizes. An isolated pulse output is available in the form of a volt free contact pair (relay switch). The contacts close for 100msec each time the LCD kWh counter increments. This output is suitable for direct connection to Building Energy Management Systems (BEMS).

A high speed internal RS485 MODBUS communications option allows all readings to be read remotely. Also available is a KW Maximum Demand option, available with or without the MODBUS option.
