We would like to graph the space's power usage (for YEARS). We have four feeds coming into the space, and three of these are three phase.
- 4 of Eastron SDM630MCT-MV - These are three phase power meters, which can also do single phase for the fourth unit, and we can get them for ~£40 each. So, £160 total.
- 3 of Eaton EMBH306 MCB - The meters need their own three phase power for accurate measurement of reactive and active power. They are also around £40 each. £120 total.
- 1 of Eaton EMBH106R30C RCBO - For the single phase install. ~£40
- 4 of RS PRO Steel Wall Box, IP66, 250 mm x 250 mm x 150mm (189-6588) - To prevent it from being a safety hazard. £46.67 each so £186.68
- 2 of RS PRO Steel Slotted DIN Rail, Top Hat Compatible, 500mm x 35mm x 7.5mm (467-406) - For mounting things. £10.94 total
- RS PRO 30A Rail Mount Fuse Holder for 5 x 20mm Fuse, 1P, 500V (Bag of 10 – 242-0497) - £36.5 total
- MCU, RS485 and Ethernet bits. Aaron will build and cover
Total for all parts £544.12
The Eastron power meters are fairly reputable (BizSpace use the same model!), and have RS485 output, so we can easily interface with them to provide statistics.
