VFD-EL-W

VFD-EL-W frequency converters are designed to solve simple tasks using an AC drive. For example, as speed control of low power pumps and fans, conveyor belts, drums, small machines, etc.

Functionally and structurally, the VFD-EL series of frequency converters is able to replace two old series (Delta Electronics VFD-L and Delta Electronics VFD-S), having a number of technical advantages over them and being in the same price range.

VFD-EL-W is a new generation of high-performance compact vector control inverters that inherit Delta inverter technology. This frequency converter includes a number of critical features for greater application flexibility.

By saving space, reducing setup and wiring time, providing high efficiency and high system stability, it is your key to becoming more competitive in the market and ensuring success.

They have high-precision current sensing, overload protection, and a built-in keyboard.

The economical series of compact frequency converters  is designed to control the rotation speed of three-phase asynchronous electric motors with a squirrel-cage rotor with a power of 0.2 to 3.7 kW as part of equipment such as pumps, fans, mixers, extruders, conveying and lifting mechanisms and etc.

Main advantages of VFD-EL-W frequency converters:

  • Vector control mode for asynchronous motors
  • Easy maintenance and commissioning
  • Due to efficient cooling, dense installation of frequency converters is possible
  • Compact design, DIN rail mountable
  • PID controller
  • Special pump control parameters (liquid leakage accounting, sleep mode)
  • Volt-frequency control
  • Formation of V/f characteristic at three points
  • Built-in RS-485 (MODBUS) port
  • Possibility of connecting additional communication adapters for ProfiBus, DeviceNet, LonWork and CANopen networks
  • VFD PC software and optional PU06 remote control
  • Protection degree IP20

Protection of VFD-EL-W frequency converters from emergency and abnormal modes:

  • Overvoltage and undervoltage
  • Overcurrent and undercurrent
  • External shutdown
  • Ground fault protection
  • Radiator overheating
  • Engine overheating

Power range of VFD-EL converters

  • 1-ph/ 220V: 0.2 ~ 2.2 kW
  • 3-ph/ 380V: 0.4 ~ 4.0 kW

Applications

  • Ventilation systems
  • Water supply systems
  • Temperature control in ovens and ovens
  • Weaving machines
  • Packaging machines, winders/rewinders
  • Film production
  • Belt Conveyors
  • Ventilation and drying chambers and other equipment
