Off-the-Shelf VFD for Immediate Implementation
At Control Resources, we understand the need for reliable, ready-made Variable Frequency Drives that seamlessly integrate into your systems. Our off-the-shelf SmartFan Stratus II VFD is designed to control single-phase and three-phase fractional HP motors from a single-phase line. Motor speed is regulated based on control signal inputs; 0-10VDC, 4-20mA, transducer, potentiometer, or thermistor.
Key control settings for the SmartFan Stratus II VFD include:
- idle speed
- full speed
- motor off
- alarm trip points
These and other settings can be programmed using the SmartFan Navigator remote programmer or via MODBUS. Additionally, CRI can factory-customize your settings for orders as small as 50 units.
