GD200A-018G/022P-4 Variable Frequency Drive GD200A 18.5kW 3-ф/380

GD200A-018G/022P-4 — three-phase frequency inverter from INVT GD200A series, rated at 18.5 kW active power capacity (nominal output current 38 A) for electrical grids with 3-phase 380V supply voltage. The VFD supports scalar V/F control, delivering smooth motor speed adjustments and dynamic torque response. The device features IP20 protection standard, integrated EMC filter, built-in braking unit, and built-in Modbus RTU RS-485 communication interface.

Typical Applications:

• Industrial conveyors, mixers, extruders, and packaging machine drive systems.
• HVAC fans and automated pump systems utilizing built-in PID controller for constant pressure hold.

Please Note: Perform motor autotuning (rotating or static) before first system startup. When installing motor cables longer than 50 meters, an output reactor (du/dt filter) is highly recommended to protect motor winding isolation from voltage spikes.

INVT GD200A — Heavy Duty / Pump Duty Dual Rated Frequency Inverter

The Goodrive200A (GD200A) series is a heavy-duty industrial workforce of the INVT catalog, uniquely distinguished by its dual power ratings (G and P modes). The inverter can be configured for constant torque applications requiring high breakaway torque (G mode - Heavy Duty, 150% overload capacity) or centrifugal fan and pump systems (P mode - Pump/Normal Duty, 110% overload capacity). This dual personality permits remarkable capital expenditure savings. GD200A features highly precise Sensorless Vector Control (SVC) alongside standard V/F algorithms, incorporating an integrated C3 EMC filter, independent cooling ducts, and double conformal board protection.

GD200A Ideal Applications

• Municipal water supply stations: Driving massive centrifugal pumps using integrated PID loops for closed-loop pressure regulation and cascade motor management.
• Industrial exhaust fans and high-inertia blowers: Safe startup of heavy fan systems with integrated «catch-a-spinning-motor» speed tracking logic to protect high-inertia systems.
• Heavy-duty industrial conveyors: Reliable soft-starting under full load conditions in G-mode, providing stable gravity deceleration controls and anti-slip protection.

What Sets GD200A Apart From Competitors

The supreme advantage of the GD200A is its versatile application configuration. While the competitors from Delta and Danfoss focus exclusively on lightweight pump/fan applications, GD200A easily powers heavy conveyors and industrial machinery in G-mode.

When GD200A is NOT Suitable

• If your configuration mandates closed-loop shaft locking at zero speed or precise motion positioning with physical rotary encoder feedback, specify the smart flagship closed-loop series INVT GD350.
• For simple low-power single-phase machinery or basic exhaust fans below 0.4 kW, the mini scalar INVT GD10 series is highly recommended.

Our Practical Experience with GD200A

The GD200A is a massive best-seller in Ukrainian water utility projects. The dual-rating architecture allows installers to select an inverter one physical step smaller than the nominal motor power when running standard centrifugal pumps (P-mode). The most critical action during the initial commissioning is switching parameter P00.04 to 1 (P-type load), which instantly updates the motor current limits and realigns the electronic thermal overload safety curves.
