Delta Bypass Panels play an important role in a system to reduce energy usage,optimize AC motor speed control, extend motor life, and reduce overall cost. The bypass capabilities allow the motor to be operated from either the Delta VFD or at full speed, directly across the line. The Delta Bypass Panel sets a benchmark for cost, performance, quality, and custom engineered bypass panels. Delta offers both the standard bypass panel, or our custom engineered panel to fulfill all your specification requirements.

Compact and Versatile Design

Engineered for efficiency, the Delta VFD022EL21A combines a compact, rectangular form factor with easy wall or panel mounting options. The drive sports a matte finish, robust polycarbonate insulation, and a lightweight build at just 1.0 kg, making installation straightforward for a variety of motor control applications.

Robust Performance and Easy Control

Delivering 2.2 kW (3 HP) of rated power and up to 150% starting torque at low frequencies, this VFD integrates both analog and digital programming to suit different user requirements. Enjoy consistent performance with an output frequency range from 0.1 to 600 Hz and built-in DC braking, all managed via a clear 7-segment LED display.

Advanced Protection and Efficiency

IP20-rated and fortified with multiple protections, the VFD022EL21A ensures reliable operation, safeguarding against overload, overcurrent, overvoltage, and overheating. Its high efficiency (over 93%) and power factor (>0.98) make it an energy-conscious choice for continuous operation between -10C and +50C, in humidities from 5% to 95%.

FAQ's of VFD022EL21A Delta VFD:

Q: How do I install the Delta VFD022EL21A for optimal performance?

A: For best results, mount the VFD on a wall or panel using its screw terminal connections, ensuring the surrounding temperature is between -10C and +50C. The device should be installed below 1000 m altitude to avoid derating. Adequate spacing should be provided for its forced air cooling system.

Q: What process should I follow to program and control the VFD?

A: Programming the VFD022EL21A is straightforward with options for both potentiometer adjustment and digital entry through its 7-segment LED display. You can set parameters such as output frequency, acceleration/deceleration times, and motor control modes directly on the VFD using the keypad or interface.

Q: When should I use the built-in DC braking function?

A: The built-in DC braking is especially beneficial during rapid stops or deceleration phases, as it helps bring the motor to a halt efficiently, reducing mechanical wear and enhancing safety during emergency situations.

Q: Where is the VFD022EL21A best applied in industrial automation?

A: This VFD is ideal for a wide range of motor speed control applications, including conveyor systems, fans, pumps, and other machinery used in industrial automation that requires three-phase output from a single-phase input.

Q: What are the main benefits of using this specific Delta VFD model?

A: Key advantages include its compact and lightweight design, high starting torque, multiple protective features, energy efficiency over 93%, and ease of installation and programming. The inbuilt EMI filter and efficient cooling contribute to long-term durable operation.

Q: How does the VFD handle varying environmental conditions?

A: Designed to operate efficiently in temperatures from -10C to +50C and humidity levels from 5% to 95% (non-condensing), the VFD022EL21A maintains reliable performance across diverse industrial environments.

Q: What usage precautions should I consider to ensure safe and long service life?

A: Ensure proper ventilation around the drive, avoid installing above 1000 m altitude without derating, and always wire according to the terminal recommendations. Regular maintenance and checking of the air cooling system will help preserve its performance and extend service life.
