Nidec Drives HVAC Drive H300 Efficiency and reliability in HVAC Specialist Drive

The 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. part of the Specialist series of industry-specific drive technologies,

builds on our company’s five decades of drives expertise, delivering precise, dependable

flow control.

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.

The drive for building HVAC

The HVAC Drive H300 has been designed to meet the needs of:

Consultants and design engineers

• All the necessary features to meet your building HVAC project specification

requirements.

• A highly reliable product and support service: Simply specify, install and forget.

Contractors

• Fast, easy and secure installation, commissioning and maintenance.

Owners of commercial buildings

• Achieves maximum building occupant comfort.

• Optimum energy saving and value with rapid ROI.

A complete HVAC

Building automation solution

The HVAC Drive H300 is optimised for fan/compressor

control in HVAC applications and has all the features

you would expect from a dedicated HVAC drive and more:

Easy integration building automation systems

• Seamless integration with Building Automation Systems with your

choice of communications protocols:

• BACnet MS/TP Supported Onboard, BACNet Testing Laboratories (BTL) Certified

Conformance.

• Modbus RTU communications.

• BACnet/IP supported though add on communications option module, BACNet

Testing Laboratories (BTL) Certified Conformance.

• Connect with a wide range of other devices using Fieldbus and industrial Ethernet

networks through add on option modules.

Custom software

• Flexibility without a Building Management System with optional

modules for running custom application software.

Fire mode

• The HVAC Drive H300 has onboard Fire mode which allows the drive to

continue running uninterrupted in the event of a fire. It can allow the

safe extraction of smoke while the drive’s other functions are

maintained.

High efficiency operating modes

• Quiet operation with Rotor Flux Control modes, high switching

frequencies (up to 16 kHz).

• Intelligent 10 speed drive cooling fan with minimum noise operation.

• Activating the Low Load Power Saving Function dynamically reduces

the voltage applied to the motor to optimize energy efficiency at

every speed and operating point.

Control Techniques

in HVAC

The HVAC & Refrigeration market was identified as the largest single

segment for growth within Motor Drive Markets in 2020*

As HVAC & Refrigeration global demands increase, so does the need for efficient

operation and saving energy.

Drives are highly concentrated in the HVAC & Refrigeration market and play a key

part in reducing energy consumption – Control Techniques’ HVAC Drive H300 drives

builds on decades of expertise to provide flexibility and reliability within this rapidly

growing market.

Extreme operating conditions

Operate in conditions from -20°C to 55°C* (40 °C as standard, above with derating).

Extended connectivity

As well as supporting BACnet MS/TP, BACnet/IP and Modbus protocols, H300 enables

extended connectivity with SI option modules (POWERLINK, EtherNet/IP, Modbus

TCP/IP, PROFINET, PROFIBUS, DeviceNet and CANopen)

Quick commissioning

HVAC Drive H300 portable memory devices: A Smartcard enables simplified

maintenance and commissioning without a PC, storing parameters and system

upgrades.
