Instrumentation aratohu
Ngā loop tohu, te whakawhenua screen me te drain, me te pupuri i te taura instrumentation kia wehe i te power.
- 3 meneti te pānuiBattery backup for a PLC panel at 24 V DCSizing a 24 V DC backup bank for an 80 W PLC panel over one day of autonomy, with the daily energy, the daily charge and the bank capacity the tool returns.
- 3 meneti te pānui24 V DC voltage drop on an instrument loopA 4-20 mA loop runs 200 m on 2.5 mm² at 24 V. See the mV/A·m figure, the 7.51 percent drop and the maximum length the engine returns for a 10 percent limit.
- 5 meneti te pānuiDC cable size: 48 V battery and 600 V PV arrayTwo d.c. circuits sized to AS/NZS 3008.1.1:2025, a 48 V battery-to-inverter run that current sizes and a 600 V array feed that voltage drop sizes.
