In this document, you find basic information about AQT530 power consumption. Consumption varies in different climates to provide the most accurate data possible. Temperature and relative humidity (RH) are the most critical factors. In powering design, the average value gives you a guideline of the power consumption during a longer period of time. The peak power consumption gives you a guideline for the maximum power needed from the power supply.
| Property | Description/Value |
|---|---|
| Operating voltage |
10 - 25 V DC Max. 1 A at 10 V DC 1 |
| Power consumption, max. peak 1 | 10 W |
| Power consumption (average with default settings) | |
| Gas and particle measurement | 1.8 … 4.4 W 2 |
| Gas measurement | 1.4 … 3.8 W 3 |
| Particle measurement | 1.7 … 2.0 W 4 |
Gas measurement only
Power consumption depends on the relative humidity condition.
Recommendation for the powering design:
- Average power consumption: 1.4 ... 3.8 W when RH ≤ 85 %
- Peak power consumption: 3.8 W when RH > 85 %
Particle measurement only
Average power consumption is defined for the default measurement cycle. The default measurement period is 1 minute and it is performed every 10 minutes. During this sample the power consumption is 4 ... 8 W depending on the outside temperature.
When the temperature is < 0 °C (32 °F), the power consumption begins to increase until below −20 °C (−4 °F) it reaches a maximum of 8 W during the sample.
If you increase the sampling interval, the average power consumption increases accordingly.
Recommendation for the powering design:
- Average power consumption: 1.7 ... 2 W
- Peak power consumption: 8 W when temperature < 0 °C (32 °F) and particle measurement is active
- Peak power consumption: 4 W when temperature ≥ 0 °C (32 °F) and particle measurement is active
Gas and particle measurement
When AQT530 is equipped with both gas and particle measurement units, the average power consumption depends on both relative humidity and temperature.
Recommendation for the powering design:
- Average power consumption: 1.8 ... 4.4 W
- Peak power consumption: 10 W when temperature < 0 °C (32 °F), RH > 85 %, and particle measurement active
