CHZIRI ZVF300H 2.2 kW 3 HP Three-Phase Variable F | RFQ Sourcing Details

The CHZIRI ZVF300H-G2R2T4SD is a 2.2 kW, 3 HP variable-frequency drive designed for controlling AC asynchronous motors. Its stated 380–440 V power-supply range and three-phase output make it suitable for industrial motor-control projects where the electrical supply and motor ratings match the drive.

Listed applications include air blowers, fans, water pumps, conveyors, handling machinery, industrial washing equipment, wire-drawing machinery, textile equipment, paper-making equipment, and other mechanical systems.

Supported product details The drive uses an AC-DC-AC voltage-source architecture with IGBT power modules and PWM switching. Available control functions include V/F control, open-loop vector control, and torque control.

The listed features include configurable V/F curves, multi-inflection-point settings, 15-step speed control through external terminals, wobble-frequency operation, automatic current and voltage limiting, undervoltage restraint, automatic voltage regulation, and built-in PID regulation for closed-loop control of variables such as temperature, pressure, and flow.

An LED display and a remo e drives. Communication is provided through RS485 using the Modbus protocol for integration with PLCs, industrial computers, and other compatible control equipment. Protection functions listed for this model include overtemperature, overload, overvoltage, and overcurrent protection.

The enclosure rating is IP20. The product is supplied in a standard export package, and the stated production capacity is 2,000 pieces per month. Customization is listed as available, and the stated warranty period is 16 months.

Procurement questions to confirm Before ordering, confirm the input phase arrangement, nominal supply voltage, frequency, allowable voltage tolerance, and the exact motor nameplate data.

Verify that the selected drive can support the motor’s rated current, starting torque, duty cycle, speed range, and load characteristics;the 2.2 kW or 3 HP label alone is not sufficient for final sizing.

Buyers should also confirm the required braking arrangement, external resistor compatibility, carrier-frequency limits, ambient temperature, installation altitude, cooling clearances, cabinet ventilation, and any derating requirements.

For blower applications, verify the intended control method, PID sensor and signal requirements, minimum safe motor speed, acceleration and deceleration times, and whether motor thermal protection or additional external protection is needed.

For control-system integration, request the applicable Modbus register map, supported baud rates, terminal diagram, digital and analog I/O details, keypad cable requirements, parameter list, and programming documentation.

Confirm the exact scope of customization, included accessories, packaging contents, inspection documents, applicable conformity documentation, warranty procedure, and after-sales support terms before issuing a purchase order.
