Product description

Easy-to-use variable speed drive (VSD) to control fans or centrifugal pumps with three-phase 230 Volt motors in HVAC applications. The VSD requires a supply voltage of single-phase 230 Volt while it controls three-phase 230 Volt motors.

This drive can control motors with a maximum (combined) current of 4.3 A. It is designed to control three-phase 230 Volt IE3, IE4, permanent magnet, brushless DC or synchronous reluctance motors.

The motor speed can be set via the intuitive keypad or via the inputs. It is possible to select a pre-defined motor speed by activating a digital input. Another option is to use a 0-10 Volt signal to define the motor speed. Configuration of this all is simplified via 14 basic parameters and application macro functions.

The enclosure can be DIN rail mounted in an electrical cabinet. It offers an IP20 protection against ingress of dust. The integrated EMC filter is Class C1.

Additional specifications and description

User-friendly variable speed control
A variable fan speed controller regulates motor voltage only. A frequency inverter also controls the motor frequency in addition to the motor voltage. On the one hand, there is the advantage of optimal motor control and more energy-efficient operation. On the other hand, there is the higher cost and the need to set some necessary parameters before commissioning. The fact that motor voltage and motor frequency can be controlled provides additional control options and thus additional parameters. To make the device as user-friendly as possible, application macro functions have been created. The main settings are grouped into the 14 basic parameters - these can be found on the help card in the enclosure.

IP20 enclosure for DIN rail or surface mounting
The enclosure is made of high-quality plastic. The design allows the device to be installed on a DIN rail or on a flat surface. The housing offers an IP20 protection rating against the ingress of dirt and moisture. We recommend to install this device in an electrical cabinet and to ensure that the ambient temperature remains within the range of -10 - 40 °C.
Easy to use
Connect Frequency inverter inputs
By selecting one of these application macros, the most important settings are pre-configured automatically. It saves you to define the functionality for the different inputs. These functionalities are pre-defined in the application macros. They offer the ideal energy saving solution where high starting torque is not required. Typical applications are AC fans, blowers, centrifugal pumps, fume extractors and air flow controllers.
By default, input 1 is used to start the motor. An optional 10K potentiometer can be connected to terminals 5, 6 and 7 to adjust fan speed. 
When input 3 is activated, the motor runs at the predefined speed in parameter 20. When input 3 is not activated (or not connected), the motor speed can be adjusted via the external potentiometer (or analogue control signal).
Pulse-width modulation
Frequency inverters control motor voltage and motor frequency via a technology called pulse-width modulation. This technology converts the supplied AC voltage into DC voltage. A frequency inverter has a DC bus, which can be seen as a buffer tank for the available energy. This buffer tank is filled both by the supply voltage (via the rectifier) and by regenerative energy from the motor that flows back during braking. This DC voltage is converted back into a kind of alternating voltage by IGBTs. IGBTs or Insulated Gate Bipolar Transistors are bipolar transistors with an insulated gate terminal that can switch high electrical current at high speed. Thanks to the smart control of the IGBTs, both the motor voltage and the motor frequency can be controlled. This enables optimum motor control and energy-efficient operation.
This frequency inverter requires a single-phase 230 V power supply. It controls standard 3-phase 230 V IE2, IE3 and IE4 induction motors. On top of that, it can also control Permanent Magnet motors, Brushless DC Motors and Synchronous Reluctance Motors.
Standard built-in EMC filter class C1
A disadvantage of high-frequency switching IGBTs is the fact that they pollute the electrical network with higher harmonic interference signals (EMC pollution). To minimize this network pollution, an EMC filter class C1 is built in as standard. This blocks the pollution and reduces interferences with other electronic devices installed in the surrounding area. However, the EMC filter only is not sufficient to eliminate all interferences. In addition to the EMC filter, correct installation and wiring are required to minimize interferences. Power cables should always be separated from signal and network cables.
