Variable Frequency Drive for Fan & Pump Applications – Unique Eco Vector Sensorless Control – Open Loop Permanent Magnet Vector – Open Loop BLDC Vector – Open Loop Synchronous Reluctance Vector – BACnet and Modbus RTU onboard as standard – Frame size 1-5 utilize film capacitor in the DC link, providing exceptionally low harmonic current distortion without compromising efficiency – Frame size 6-8 include DC chokes and traditional electrolytic capacitors

HVAC BUILDING SERVICES – Maximum Fan Efficiency – Accurate speed control of fans and pumps provides the most energy efficient control method – Energy optimization function minimizes energy usage in real time under partial load conditions – Sleep & wake functions ensure operation only when required – Advanced on-board features remove the need for peripheral equipment – Intelligent maintenance interval timing allows programmable maintenance reminders, avoiding costly downtime – Automatic load monitoring provides an early warning of potential faults, such as belt failures or blocked filters – Building Safety Systems: Stairwell Pressurization, Fume Extraction, Fire Override – Fire override: Mode ignores signals and alarms, keeping the drive operating for as long as possible – Energy Efficient Air Handling: Can vary the output of air conditioning system to meet the varying demands throughout the day, maximum occupancy and peak outside ambient – Belt Break Detection: Provide immediate warning of broken belt between motor and fan

PUMP CONTROL – Maximum Pumping Efficiency – OPTIFLOW technology allows simple operation of multiple pump sets without the need for a PLC – Pump blockage detection and cleaning dramatically reduces pump maintenance requirements – Built-in PLC function – Dry Run Protection: Drive can evaluate pump’s speed/power and shut it off or warn when the pump starts to run dry – Motor Preheat Function: insures moisture does not collect on the motor in periods of inactivity and prior to motor start up – Pump Stir Cycle: Triggered by a settable period of inactivity, a configurable cleaning cycle can be run to clear sediment – Consistent Flow: Pump operating curve detection automatically detects and monitors normal pump behavior and is able to react when pumping conditions change – Pump Prime with Burst Pipe Detection: helps to prevent the effects of water hammering – Advanced sleep & wake functions provide maximum energy savings by switching off the pump when not required – Any pump can be switched to Hand operation a the touch of a button, and will automatically rejoin the network when switched back to Auto – For waste water applications, each pump can be set for blockage/ragging detection and activate an automatic de-ragging/pump cleaning cycle
