Variable Frequency Drives
Benshaw, Siemens, and LSIS VFDs | Precision Speed Control & Maximum Energy Efficiency
Variable Frequency Drives (VFDs), also known as AC drives or adjustable speed drives, are the ultimate solution for optimizing industrial motor performance. Unlike standard starters, a VFD allows you to precisely control motor speed and torque, matching the energy output to the actual requirements of your application. This results in significant energy savings, reduced mechanical wear, and a longer lifespan for your equipment.
At Kent Electrical Supply, we stock a vast inventory of high-performance drives from Benshaw (RSI Series), Siemens, and LSIS. Our range covers everything from compact 1 HP micro-drives to robust 800 HP industrial power stacks, supporting 230V and 460V 3-phase systems.
Why Upgrade to a Variable Frequency Drive?
- Unmatched Energy Savings: Reducing motor speed by even 20% can cut energy consumption by nearly 50% in centrifugal pump and fan applications.
- Precise Process Control: Features like Sensorless Vector Control and built-in PID loops allow for automated regulation of flow, pressure, and temperature.
- Reduced System Stress: Controlled acceleration and deceleration eliminate mechanical shocks, preventing belt slippage and pipe water hammer.
- Advanced Integration: Many of our drives, like the Benshaw H2 series, come standard with BACnet and Metasys-N2 for seamless building automation.
VFD Enclosure & Duty Rating Guide
| Feature | Industrial Benefit |
|---|---|
| NEMA 4X / Washdown | The Benshaw S4 Series is built for harsh, high-pressure cleaning environments. |
| Dual Duty Ratings | Most drives are rated for both Standard Duty (120% overload) and Heavy Duty (150% overload). |
| Outdoor Enclosures | We offer NEMA 3R and NEMA 12 options for outdoor and severe-duty installations. |
| Internal Braking | Built-in Dynamic Braking IGBTs provide rapid deceleration for high-cycle applications. |
Whether you need to control a single pump or a complex multi-motor system, our technical team is ready to help you select the right drive. We carry specialized series for HVAC, water treatment, and heavy-duty material handling. In-stock VFDs typically ship within 24 hours to keep your facility running at peak efficiency.
Need Technical Assistance? Because VFD sizing depends on your specific load type (Variable Torque vs. Constant Torque), please call us at 800-222-5129 for expert guidance on your motor control project.
