Motor Compatibility
For maximum motor life without using a line filter, the use of an inverter duty motor is recommended.
Changing Control Settings
The Stratus will not recognize any changes in switch settings made with power applied. To avoid electrical shock, it is recommended that power be turned off for 30 seconds before changing any switch settings.
Electrical Noise Emissions and Filtering
Electrical noise emissions (EMI) are highly dependent on load and environment. For many applications no additional filtering is required to meet EN55011/FCC class A emissions standards. For applications requiring additional filtering CRI recommends the following filters or equivalents:
Controlling Multiple Motors
Multiple motors wired in parallel can be controlled from one Stratus VFD as long as maximum peak (startup) currents do not exceed 10 Amps.
Control Accuracy and Hysteresis
Control signal accuracy is as follows:
- Voltage: +/- 0.38VDC
- Current: +/- 0.4mA
- Temperature: +/- 1.5°C
In alarm conditions, loss of signal and ON/OFF feature, hysteresis is added to eliminate cycling. Hysteresis is as follows:
- Voltage: +/- 2%
- Current: +/- 1.5%
- Temperature: 1-2°C
RoHS compliance
Contact customer service for the latest compliance information.
Maximum Fan Currents
Some motors draw higher current at less than maximum voltage. Contact motor manufacturer for details.
HiPot Testing
The Stratus is designed to withstand HiPot testing to 1500Vrms, line input to analog input, motor output to analog input.
Current Derating
TheStratus may be run above 40˚C. However, the maximum current ratings will decline according the chart below.
