Stratus II Variable Frequency Drive AC Motor Speed ControlOperation/Installation Manual
MOTOR COMPATIBILITY
For maximum motor life without using a line filter, the use of an inverter duty motor is recommended.
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:
EN55011/FCC class A:
150KHz – 30mHz EN55011/FCC class B:
10KHz-30mHz Filter Concepts: LE series
www.filterconcepts.com Filter Concepts: LX series
www.filterconcepts.com Corcom S series,

Controlling multiple motors: Multiple motors wired in parallel can be controlled from one Stratus II 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 ± 1.5Cº
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 1-2Cº
RoHS compliance: Stratus II is RoHS (6/6) compliant
Maximum Fan Current: Some motors draw higher current at less than maximum voltage. Contact motor manufacturer for details.
HiPot Testing: Stratus II is designed to withstand HiPot testing to 1500Vrms, line input to analog input, motor output to analog input.
