Roller shutter doors typically have low power consumption.
Taking a common electric roller shutter door as an example, the power consumption for a single opening/closing cycle is approximately 0.05-0.15 kWh (calculated based on motor power and operating time). Assuming 20 operations per day, the monthly power consumption is approximately 15-45 kWh, classifying it as a low-power device. Specific power consumption is significantly affected by the following factors:
Motor Power: Mainstream commercial roller shutter door motors range from 200W to 800W, while household models are mostly 100W-300W. For example, a 400W motor consumes 0.4 kWh in one hour, while a single opening and closing typically takes only 20-30 seconds.
Usage Frequency: In high-frequency usage scenarios such as shopping malls and garages (more than 50 times per day), power consumption can be 3-5 times that of household use (5-10 times per day).
Auxiliary functions: Systems with automatic sensing, remote control, or network connectivity will increase standby power consumption (approximately 5-15W/hour), but this accounts for less than 10% of total power consumption.
Energy-saving design: New variable frequency motors can reduce energy consumption by 30%, while mechanical balancing systems (such as torsion spring counterweights) can reduce motor load, further saving energy.
