INVT GD270 series compact vector inverters

GD270 is the new INVT series of compact vector inverters designed for normal load applications such as pumps, fans, air compressors, refrigeration compressors, etc.
For all these applications, the GD270 series offers a full range of features and unparalleled energy efficiency combined with an extremely competitive price.

Featuring an ultra-compact book format, GD270 is available in a power range of 1.5KW to 500KW, with power class 400Vac.

The GD270 series has EMC filter level C2 as standard up to 22kW power and C3 for subsequent sizes.

The GD270 inverter is suitable for driving asynchronous motors and permanent magnet synchronous motors indifferently.

GD270 offers as standard all the features required of an inverter intended to drive pumps or fans including:

• Superior energy efficiency through ECO-MODE
• Advanced multi-pump control
• Dual PID controller
• Fire Mode
• Condensation prevention and antifreeze function
• Pump block prevention function
• Fan belt breakage management
• Advanced management of power supply voltage dips

The inverter's printed circuit boards are protected with resin for use in harsh environmental conditions.

Energy saving with ECO-MODE

The innovative ECO-MODE mode of operation available in the GD270 series can contribute, along with other interventions, to achieving the energy-saving goals set forth in the Transition 5.0 Plan, offering a noticeable advantage, in terms of consumption, over control modes with traditional Inverters.

ECO-MODE optimizes the efficiency of the motor-inverter system in a fully automatic way, acting directly and independently on the voltage/frequency curve and establishing the optimal V/F ratio for maximum motor efficiency under any load and speed conditions.

ECO-MODE allows the greatest energy savings in machines that do not require frequent acceleration and deceleration, allowing the system to self-regulate and, if necessary, autonomously shut down in the face of sudden changes in frequency and/or load.

Activation of the ECO-MODE function is done with a single parameter, no complex programming, no detailed knowledge of system dynamics. If the application allows it, ECO-MODE will allow the system to reduce its consumption totally autonomously, without impacting machine operation.
