INVT GD270-1R5-4 frequency converter

INVT GD270 helps HVAC systems achieve intelligent energy saving

1. Ideal driving solution for central air conditioning system
In the central air conditioning system, fans and water pumps are the main energy consuming equipment, and the traditional constant speed operation mode causes a lot of energy waste. The INVT GD270 fan water pump dedicated frequency converter can accurately adjust the motor speed according to actual load requirements, achieving on-demand energy supply. It supports multi-stage pressure setting function, and can achieve 16 stage pressure regulation through different combinations of 4 terminals, meeting the air conditioning load requirements of different time periods and regions.

2. Intelligent PID control achieves precise temperature regulation
INVT GD270 is equipped with a high-performance PID controller that can quickly respond to changes in temperature and pressure, achieving precise closed-loop control. The frequency converter supports analog input and output, and can be easily connected to field instruments such as temperature sensors and pressure sensors. At the same time, it also has an automatic voltage adjustment function, which can automatically maintain a constant output voltage when the grid voltage fluctuates, ensuring stable operation of the system.

3. Multi pump wheel circulation control extends equipment service life
The central air conditioning system usually adopts the parallel operation of multiple water pumps. The multi pump wheel circulation control function of INVT GD270 can automatically balance the running time of each water pump, avoiding premature damage caused by long-term continuous operation of a certain water pump. When the water supply pressure is insufficient, the running variable frequency pump will automatically switch to power frequency operation, and then the variable frequency will switch to the next pump for variable frequency control, achieving smooth load transfer.

4. Comprehensive protection functions ensure system security
INVT GD270 provides comprehensive fault protection functions, including overcurrent, overvoltage, undervoltage, overtemperature, phase loss, overload, etc. Of particular note is its power outage non-stop function, which ensures continuous operation of equipment without stopping in the event of short-term fluctuations in the power grid. In addition, the frequency converter also supports automatic restart function after power outage, without manual intervention, greatly improving the automation level of the system.
