The company’s innovative products are used in the most demanding applications requiring reliability, energy efficiency and performance. With facilities across Europe, the Middle East, Africa, the Americas and Asia, Control Techniques can offer local technical sales, service and design expertise to customers around the world.

Emerson Powerdrive F300 series high power modular frequency inverter.

Optimum energy efficiency for fan, pump and compressor applications.
Control Techniques offers a full range of high powered drive products tailor-made for the fan, pump and compressor market from 90 kW to 2.8 MW. The Powerdrive F300 series has a modular design and can control permanent magnet or standard AC induction motors. The modular approach to building high power systems provides the flow industry with flexibility while keeping complexity low. Modules with integrated rectifiers and/or line chokes can be easily paralleled, keeping installation time and component count to a minimum. Separate inverter and rectifier modules can be paralleled into more flexible common DC bus and regenerative configurations. Control Techniques offers 40 years of experience and the company’s drives and motors engineers have application expertise in a variety of process markets including oil and gas, chemicals, metals, mining, water, waste water, pulp and paper, food and beverage and handling.
Powerdrive F300 offers benefits in four key areas:
- Energy efficiency
- Harmonics and drive solutions
- Reliability
- Modular construction 

Energy efficiency, low harmonics, reliability and modular construction.

Optimum energy efficiency for fan, pump and compressor applications.
Powerdrive F300 works with permanent magnet or induction motors to enable the most efficient performance and highest energy savings for fan, pump and compressor applications. The drive was designed in conjunction with permanent magnet (PM) motors from partner company Leroy-Somer: the Dyneo® solution provides the highest energy savings available on the market today. Leroy-Somer also offers a range of AC induction motors: IMfinity®. Paired with F300, the induction motor solution offers control, reliability and ease of installation and commissioning.

Induction motors: meet the new energy efficiency legislation and future proof your investment.
- Powerdrive F300 helps IE2 motors comply with the latest European Union Minimum Energy Performance Standard legislation: ➪ Makes 7.5-375 kW IE2 motors compliant with 1st January 2015 regulations ➪ Makes 0.75-375 kW IE2 motors compliant with 1st January 2017 regulations.
- Powerdrive F300 supports both induction and permanent magnet motors, meaning induction motor users can upgrade to permanent magnet without changing the drive.

Powerdrive F300: efficiency on-board.
Powerdrive F300 also increases application efficiency as a result of its own energy saving features. 
- Up to 98 % efficient with very low losses 
- Low Power Standby and Sleep/Wake Mode using programmable real-time clock (with KI-HOA Keypad RTC) ensures minimal wasted energy 
- Advanced Rotor Flux Control (RFC) features a vector algorithm utilizing closed loop current control to greatly enhance performance 
- Lower losses at part load for open loop induction motor control are achieved by dynamically changing the switching frequency based on load requirements to save energy.

Harmonics and drive conformance.
Powerdrive F300 is sensitive to its environment. It has been designed for low harmonic emissions and achieves high conformance levels. 
Total Harmonic Distortion can be reduced through: 
- Adding an AC line reactor 
- Using a 12, 18 or 24 pulse input rectifier solution
- Active Front End configuration

Environmental safety and electrical conformance.
- UL listed • Electromagnetic immunity complies with EN 61800-3 and EN 61000-6-2 
- Electromagnetic emissions comply with EN 61800-3 ➮ On-board EMC filter, category C3 ➮ Optional external EMC filter, category C2 depending on power rating and cable length • Compliance with EN 61000-3-12 with external line reactor.

Minimize downtime for critical operations.
We know how important reliability is to our customers and that every second of system downtime can be costly. Powerdrive F300 high power modules have exceptional build quality based on over 40 years of industry experience. Built using advanced manufacturing processes, the modules are packed with features proven to keep Powerdrive F300 running in the most testing of environments.

Reliability assured 
- Every Powerdrive F300 power module has been subjected to elevated temperature tests that cycle a wide range of load and thermal conditions
- Powerdrive F300 drives have conformal coating to further increase resilience to harsh environmental conditions 
- Trip avoidance features take intelligent action instead of interrupting critical processes. For example: ➮Active thermal monitoring reduces switching frequency as the drive approaches thermal limits ➮Load shedding reduces speed at current limits ➮Supply loss ride-through keeps the drive running during supply brown outs 
- Protection alarms safeguard the wider system (e.g. over current, over temperature, over voltage and short circuit protection) 
- Intelligent variable speed fans are able to ensure operating temperature stays within limits while maximizing fan lifetime by reducing wear and tear. The fans are designed for easy replacement 
- Wide supply voltage tolerance keeps operation smooth when supply is variable 
- Motor pre-heat function injects low level current when the motor is not running to prevent condensation 
- Envelope control for refrigeration compressors

Comprehensive module stocking system. 
- Standard replacements: our range is based on mass produced standard product, enabling rapid access to replacements 
- Comprehensive stock: regional centers based across the globe carry large stocks, ensuring rapid availability of drives and parts.

Emerson drive Powerdrive F300 module configurations and order information.

‘A’, ‘E’ & ‘T’ – AC in AC out modules.
Powerdrive F300’s AC in AC out modules are available in 3 frame sizes (9, 10, & 11) and comprise an integrated 6 or 12 pulse rectifier with an inverter. ‘A’, ‘E’ and ‘T’ formats can be paralleled together to reach powers of 2.8 MW (4,200 hp) and can be supplied with an optional braking transistor. Frame 9A has an internal choke that can be paralleled to 1.9 MW (6 pulse only).
