Application - Energy Efficiency

ECO Mode: Ensures optimal performance and lower losses in low dynamic loads, optimizing output power.

Result: Annual energy saving: Over 8100 kWh.

Conditions: Applicable to IE2 asynchronous motors of 4 kW. Load rate: 40%. Number of motors: 10. Operating times per year: 24 hours, 365 days. Speed control mode: V/F, VF energy-saving mode: maximum efficiency. Energy-saving gain coefficient: 100%. Energy-saving angle compensation coefficient: 80%.

Note: This is internally measured data. The actual effect differs based on the motor's features and performance.

Bypass Function: External contactors can be controlled by relays to achieve industrial frequency switching and reduce energy consumption.

Energy Saving Control: Allows for sleep mode at night or energy-saving operation under extremely low load conditions, avoiding frequent starts and stops.

Multifunctional

• Transient Voltage Drop Retention: Guarantees continuous operation of equipment during short-term power grid fluctuations.
• Multi-Pump Switching and Auxiliary Pump Start/Stop: Supports variable frequency water supply by pump in cyclic and fixed modes, and provides sleep control (Note: an additional relay board is required). The VFD does not designate one pump as the variable frequency pump. When the water supply pressure is insufficient, the running variable frequency pump will switch to the fixed frequency operation, and then the next pump will become the variable frequency pump (up to 8 variable frequency pumps can be controlled. Only one variable frequency pump can be used at a time).
• Water Pipe Filling Smoothness: The VFD prevents water hammer effect by injecting water slowly and smoothly into the water pipe during startup.
• Pipe Break Detection: Pipe break detection is performed based on the VFD's operating frequency or the upper limit of the PID output frequency.

Level Control: When the water level is below the lower level limit and above the water scarcity level, the system operates with standby pressure for abnormal cases. When the water level is below the water scarcity level, the system stops all operations.

Multifunctional Features (Continued)

• Rotational Speed Tracking (for fan): Tracks the fan's rotational speed before startup to reduce shock to devices and improve restart efficiency.
• Multi-Stage Speed Reference: A total of 16 stage speeds can be set by combining the digital inputs of the four terminals, allowing for air flow regulation by combining stages in different time periods or load conditions.
• Regeneration Prevention (for fan): A fan is in a slight regeneration state under the influence of other fans sharing the same duct. The VFD will automatically increase the output frequency to prevent overvoltage alarms and ensure stable machine operation.
• Fire Mode (for pump): In case of fire in a tunnel or building, the VFD can rapidly disperse smoke and ignore other control commands and internal protection functions to continue operating.
• Restart After Shutdown: The VFD can automatically start when the restart after shutdown function is enabled.

Safe and Reliable

• Desludging: Periodic forward, pause, and reverse rotation of the motor enables the pump's self-cleaning function, reducing manual cleaning workload.
• Independent Air Duct Design: The independent air duct effectively improves the VFD's protection effect, preventing dust from entering the machine and extracting heat from the VFD to enhance its reliability and extend its service life.
• Anti-freezing: When the ambient temperature drops below a set limit, the motor automatically rotates to prevent water from freezing, thus protecting the pump.
• Motor Heating: The VFD outputs DC current to increase the motor surface temperature during work interruption, preventing motor failures caused by condensation.
• Enhanced PCB Coating: After being reinforced with three proofs, the PCB gains a strong protection capability to withstand harsh environments, ensuring the VFD's long-term healthy operation.
• Integrated Safe Torque Off (STO) Function (only GD270-EU models support): Designed in accordance with relevant international standards, meeting SIL3 level (TUV certificate acquisition in progress).

Technical Specifications

Model Description

Product Model Designation and Selection

GD270-160-4-L1-C3-EU

Note:

The parentheses "()" in the "VFD Model" column are used to distinguish models when selecting different product configurations.

Please note that models from 11-22 kW can only be configured with either the integrated DC reactor (L1) and the integrated C2 filter.

The rated output current is the output current when the output voltage is 380 V.

The data in the "Input Current" column is measured at an input voltage of 380 V. The data in "()" is measured when a DC reactor is configured.

Expansion Board

Note: Expansion boards are optional and need to be purchased separately.

Optional Parts

Filter & Reactor

Note: The above options are for external installation; the customer needs to specify them when choosing and purchasing. They can be flexibly adjusted according to the nominal working current value.

For reactor selection with different requirements from the recommended table, please refer to the "Low Voltage GDL Series VFD Filter Options Brochure".
