Control Techniques’ HVAC Drive H300 variable frequency AC drive (VFD) is the result of extensive research and builds on our vast experience of the HVAC market.
The HVAC Drive H300 dimensions are among the smallest in its class at every power rating. This saves valuable building real estate, makes the drives easy to handle, and maximizes mounting flexibility.
As a complete HVAC/R automation solution, features of HVAC Drive H300 are:
- Easy integration with Building Automation Systems with onboard BACnet, Metasys N2 and Modbus RTU communications
- Flexibility without a Building Management System with optional co-processor for running custom application software
- Fire mode for occupant safety which allows the drive to continue to run in the event of a fire for smoke extraction or pressurizing a room
- Quiet operation with Rotor Flux Control modes, high switching frequencies (up to 16 kHz), and an intelligent 10 speed drive cooling fan with minimum noise operation
- High product reliability with conformally coated PCBs as standard
- Easy system installation and ongoing management with intuitive PC tools and useful VFD features
- High energy efficiency, up to 98%
- Dynamic Volts/Hertz energy optimization
- Sleep, Wake, and VFD standby modes
- Motor control of super high efficiency sensorless permanent magnet motors
- Among the most compact VFD in its class at every frame size
