Description

Delta EL Series VFD 007EL21A

Features:-

♦ Standard Modbus Protocol-Standard Modbus protocol via RS-485.

♦ 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.

♦ Built-in EMC Filter- The built-in EMC filter reduces electromagnetic interference and complies with the EN61800-3 standard

(230V single-phase and 460V 3-phase)

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

♦ 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.

♦ Optional Fieldbus Modules-

Provide connection to a variety of networks, including PROFIBUS, DeviceNet, and CANop.

Applications:-

♦ 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.

♦ Winders-

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 aauto-detectionof 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.
