- SmartFan Stratus II VFD (variable frequency drive) is designed to control single or three-phase fractional HP, inverter grade motors via a transducer (voltage or current signal), building automation system (voltage, current signal, Modbus), thermistor, potentiometer, contact closure or Modbus RTU network. This VFD can be customized in minutes using the menu driven SmartFan Navigator handheld remote programmer or through the Modbus communications port.
- Three programming options:
+ SmartFan Navigator PRG02-F handheld remote
+ Windows PC USB port using a Modbus master application
+ Factory customization and programming for orders as small as 50 pieces
- Programmable variables include:
+ Control slope, 4 variables including on/off at idle
+ Alarm trigger point and direction
+ Ramp up and ramp down rates
+ Programmable current limit up to 10 Amps
+ PWM frequency
+ Motor frequency and direction
+ Contact closure polarity and frequency
- Over temperature protection
- Available with or without metal safety enclosure
- Contact closure allows settable on/off override option
- On-board status LEDs
