Accepted Answer

For a 280kW motor, the FR-HEL-H280K is the recommended VFD. It provides 0A output current with proper safety margin. Always match VFD rating to motor nameplate current for optimal performance.

Question 4

What voltage does FR-HEL-H280K support?

Accepted Answer

The FR-HEL-H280K operates on 380-480V AC input voltage. It's part of the Mitsubishi FR-HEL series, suitable for three phase power supply systems.

Question 5

What is the output frequency range of FR-HEL-H280K?

Accepted Answer

The FR-HEL-H280K provides an output frequency range of 0.2-590 Hz. This wide frequency range allows precise motor speed control for various industrial applications.

Question 6

Does FR-HEL-H280K come with warranty?

Accepted Answer

Yes, all Mitsubishi VFDs from SISL come with 12-month warranty. As an authorized distributor in Bangladesh since 2009, we provide genuine products with full after-sales support and technical assistance.

Question 7

Is FR-HEL-H280K original Mitsubishi product?

Accepted Answer

Yes, SISL is an authorized Mitsubishi Electric distributor in Bangladesh. All our VFDs including FR-HEL-H280K are 100% original Japan products with proper documentation and warranty.

Question 8

How much energy can I save with FR-HEL-H280K?

Accepted Answer

VFDs typically save 20-50% energy in pump and fan applications. The FR-HEL-H280K features optimal excitation control and energy-saving algorithms that automatically reduce power consumption during light load conditions.

Question 9

What makes FR-HEL a low harmonic drive?

Accepted Answer

The FR-HEL series uses 18-pulse or active front-end technology to reduce harmonic distortion to less than 5% THD, meeting IEEE 519 standards. This protects sensitive equipment and improves power quality in installations.

Question 10

When should I choose FR-HEL over standard VFDs?

Accepted Answer

Choose FR-HEL when power quality is critical, such as in hospitals, data centers, or facilities with sensitive equipment. It's also required when utility power quality regulations mandate low harmonic emissions.

Question 11

Is VFD and inverter the same thing?

Accepted Answer

Yes, VFD (Variable Frequency Drive) and inverter are the same thing. Other names include variable speed drive (VSD), AC drive, adjustable frequency drive (AFD), and frequency converter. All refer to devices that control motor speed by varying frequency.

Question 12

Which is better: VFD or soft starter?

Accepted Answer

VFD provides continuous speed control and energy savings, while soft starter only reduces starting current. For applications requiring variable speed or energy efficiency (pumps, fans), VFD is better. For fixed-speed applications with occasional starts, soft starter may be more economical.

Question 13

How to select VFD size for motor?

Accepted Answer

Match VFD rated current to motor full-load current (FLA) with 10-20% safety margin. For 280kW motor, FR-HEL-H280K with 0A output is recommended. Always verify motor nameplate and application requirements.
