Single to Three Phase Conversion: Converts standard single-phase AC power into synthesized three-phase output for motor operation.
Integrated Overload Relay: Built-in protection against overloads, over-voltage, under-voltage, short-circuit, and overheating.
High Energy Efficiency: Delivers 20-50% energy savings in variable load applications like pumps and fans.
Soft Start and Stop: Minimizes mechanical stress on motors and gearboxes, reducing wear and extending equipment life.
Wide Frequency Range: Output frequency adjustable from 0 to 400 Hz for precise speed control.
Robust Overload Capability: Supports 110% overload for 60s (variable torque) and 150% for 60s (constant torque).
Flexible Customization Options: Offers full customization, minor customization, and flexible customization from samples or designs.
Broad Application Scope: Ideal for water pumps, HVAC systems, conveyors, machine tools, compressors, and fans.

AI-Powered supplier vetting
SummaryThe supplier is identified as a professional technical supplier providing 3D software design, ODM, industrial automation, product sales, installation, commissioning, maintenance, and repair services. It supports extensive customization and has documented finished-product inspection instructions, quality assurance, and stated lead times within 15 working days in both peak and off-peak seasons. However, it has no overseas showrooms, agents, branches, or offline trade-show experience, and no new products were developed in the past year. Supplier-management, corrective-action, and complaint-handling procedures exist but lack written records. Certification is listed as NIL, quality-control staffing is below five, and R&D engineer experience totals two years. Export activity is established, with 31%–40% of sales from exports and three years of export experience. Evidence of specific customer cases is not provided.
Supplier typeThe supplier explicitly identifies itself as a professional technical supplier and provides industrial automation-related one-stop services, including product sales, solutions, installation and commissioning, maintenance, and repair. Its stated focus covers cement, packaging, printing, rubber, textile, and machine-tool industries.
CertificationsSupplier management system certification is explicitly recorded as NIL. The provided information therefore does not demonstrate possession of relevant certifications.
After-Sales capabilityThe supplier states that it provides installation, commissioning, maintenance, and repair services and has a quality-assurance system. However, it has no overseas showroom, agent, or branch, and its complaint-handling procedure has no written records, limiting evidence of formalized after-sales execution.
Production capacityThe supplier reports lead times within 15 working days during both peak and off-peak periods, maintains written and uniformly followed finished-product inspection instructions, and lists annual production output above the stated threshold. Nevertheless, quality-control staffing is below five and the service-capability assessment procedure has no records.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. The same capability is confirmed in two slices, providing direct evidence of broad customization coverage.
Product Q&A
Q:What is the typical warranty period for this type of VFD?
A:
Most manufacturers offer a standard warranty of 18 to 24 months from the date of shipment or installation. Some brands may offer extended warranties up to five years, often requiring authorized commissioning or a service contract. Always verify the specific warranty terms with the supplier.
Q:Can this VFD be used to power multiple three-phase motors from a single-phase supply?
A:
Yes, a single VFD can power multiple motors, but each motor requires individual overload protection on the load side of the VFD, as the VFD itself can only sense the total connected load. Consult the VFD manual for specific guidance on multi-motor configurations.
Q:How do I determine the correct VFD size for my three-phase motor running on single-phase power?
A:
Size the VFD based on the motor's Full Load Amps (FLA). For general applications, select a VFD with an amp rating at least 1.5 to 2 times the motor's FLA to accommodate starting current and potential overloads. If the motor is above 3 HP, a three-phase input VFD derated to single-phase input may be necessary, requiring a VFD rated for double the motor's FLA.
Q:What is the typical lead time for these VFDs?
A:
Lead times can vary significantly due to supply chain conditions. Currently, lead times are typically 4 to 8 weeks, though some models may be in stock for immediate deployment. For custom configurations or high-demand models, lead times can extend to several months.
Q:Does the integrated overload relay protect against single-phasing?
A:
Yes, integrated overload protection, when correctly programmed with motor nameplate data, typically includes protection against single-phasing and other electrical faults.
