DIN 96mm SINGLE LINE DISPLAY, MULTI DISPLAY ENERGY METER

A Din 96mm single line display, multi display energy meter with dual isolated volt free pulse outputs as standard for KWh & KVArh for interfacing to external equipment such as BMS systems. The CUBE 350 can also be specified optionally with MODBUS RS485 whilst still retaining the pulse outputs, plus an additional harmonics option via MODBUS is also available. The CUBE 350 is suitable for both three phase and single phase loads and if three phase both 3 wire or 4 wire balanced or unbalanced loads, inductive or resistive. The CUBE 350 is fully programmable to set up CT ratios, the CT secondary can be specified at ordering as either conventional 5 Amp or 1 Amp, or as 333mVAC which are used in application scenarios where the CT’s are sited a distance away from the meter and VA burden within the secondary cabling is an issue. The CUBE 350 auto scales to Wh, KWh, MWh etc, depending on the CT ratio programmed. The CUBE 350 is able to accept a very wide voltage input span of 80-480V L-L or 46-277V L-N, thus enabling the CUBE 350 to be used on VT circuits such as 11KV/110V, therefore a VT ratio can also be programmed if required. Optionally an additional Voltage Expander module can be ordered for system voltages from 480-690V L-L / 277-399 L-N +10%
