INVT GD290-018G/022P-4 Frequency converter, intelligent sleep mode, dedicated for fans and pumps

1.Product Overview

INVT GD290-018G/022P-4 is an Inventec GD290 series high-performance universal vector frequency converter. The G type (constant torque) has a power of 18.5kW, and the P type (variable torque) has a power of 22kW. It has a three-phase input of 380–480V, with a book-shaped high power density design. It is targeted at mid-to-high-end industrial drives, emphasizing heavy-duty reliability + precise speed control + high efficiency and energy saving. It is suitable for constant torque and variable torque loads.

2. Product Advantages
a. Strong vector control: Supports SVC/FVC/V/F three modes; at 0.5Hz output, it provides 150% torque, with a speed ratio of 1:200, speed accuracy of ±0.2%, and excellent performance in heavy-load startup and low-speed stable speed.
b. Industrial-grade high reliability: Core board is coated with thick three-layer anti-corrosion layer, dust-proof, moisture-proof, and corrosion-resistant; wide voltage range of ±15% (323–552V); built-in C3 filter + DC reactor, excellent EMC, low harmonics; IP20 protection, CE/RoHS certification.
c. Efficient energy saving: ECO algorithm + intelligent sleep mode, energy saving of 20%–40% for fans and pumps; built-in multi-pump circulation to reduce system cost.
d. Rich functions and easy expansion: Standard Modbus RTU, optional PROFINET/PROFIBUS/CANopen; built-in braking unit (≤110kW), speed tracking, power failure restart.
e. Compact and space-saving: Book-shaped design, side-by-side gap-free installation, control cabinet volume reduced by 30%+.
