Delta Sensorless Vector Control Compact Drive VFD-EL Series

Delta Sensorless Vector Control Compact Drive VFD-EL Series

Standard Modbus Protocol
Standard Modbus protocol via RS-485 

Built-in EMC Filter
(230V single-phase and 460V 3-phase)
The built-in EMC filter reduces electromagnetic interference and complies with the EN61800-3 standard

Compact Design
Space saving and easy DIN rail mounting with optional DIN rail adapter (Built-in for Frame B)

Optional Fieldbus Modules
Provide connection to a variety of networks, including PROFIBUS, DeviceNet and CANopen

RFI Switch for IT Mains
Removable "Y" capacitor to use with IT mains supplies

DC Bus Sharing
Multiple VFD-EL can be connected in parallel to share the regenerative braking energy. This prevents over-voltage and stabilizes DC bus voltage.

Complete Protection Functions
High precision current detection, full overload protection (oL, oL1 and oL2), overvoltage/ overcurrent stall prevention, short-circuit protection, reset after fault, speed search function and motor overheat protection by PTC

Power Range
Single-phase 115V series: 0.2~0.75kW (0.25~1hp)
Single-phase 230V series: 0.2~2.2kW (0.25~3hp)
3-phase 230V series: 0.2~3.7kW (0.25~5hp)
3-phase 460V series: 0.4~3.7kW (0.50~5hp) 

Side-by-side Installation (40 degree Celsius)
High-efficiency cooling and flexible spacing

Easy Maintenance
Removable cooling fan for easy maintenance

Conveyor Belts
1. Multi-step speed application: provides multi-step speed settings to meet the needs of a conveyor belt
2. Side-by-side installation to save space
3. DC bus sharing: connects multiple drives in parallel to share the regenerative energy and prevent overvoltage

Auto acceleration/deceleration function provides rapid start/stop of operation and increases productivity and efficiency

Constant Pressure Control of Water Pumps
1. Built-in smart PID controller saves the cost of a specified external PID meter
2. Built-in auto detection of water suspension and auto power-on saves the cost of external PLC controller and relay
3. A wide range of input voltages are available, including single-phase 110V/230V and 3-phase 230V/460V, for various pump applications and different countries
