User benefits

Energy saving
  • High efficiency at reduced load, i.e. energy saving
Installation
  • Electrical enclosure not required
  • No special knowledge required to install
  • Expensive screened motor cables for EMC not required
  • Wiring and important instructions attached to converter
  • "Maintenance isolator" to the MACHINERY DIRECTIVE 
  • Adjustment of fan characteristic by adapting the maximum frequency (up to typically 60 Hz), no more expensive modification of V-belt pullies
  • Earth leakage current < 3.5 mA (PE-earth connection < 10 mm˛ usually not required)
Cost advantages
  • Suitable for use with standard industrial motors, particularly important with directdriven scroll-free fans
Operating advantages
  • Motor has practically no noise as a LC sine-wave filter is integrated in the power range 1.1...2.2 kW (QT)
  • Automatically reduces power on overload or overtemperature instead of the usual trip function
  • Stepless variable-speed control (open or closed loop)

Features
  • Housing to protection class IP54 suitable for wall mounting or mounting on a machine frame without an enclosure
  • Integrated main isolator can be used as maintenance isolator
  • Integrated EMC filter to class B
    • suitable for unrestricted direct connection to public electrical supply
  • Modes of operation:
    • integrated potentiometer
    • remote setpoint 0...+10 V or 0/4...20 mA
  • Operation with single-phase motors
  • Integrated LC sine-wave filter for minimum motor noise and operation with long cable runs
  • Space for customized options

Principle of operation
 
Supply voltage is connected directly to the main isolator. When the isolator is switched on, power is fed via an EMC-filter to an input rectifier where the d.c. link voltage is produced.

The inverter stage converts the d.c. voltage into variable frequency three-phase voltage. The frequency is adjustable within the range 0...50 Hz. This range may be extended to 60 or 87 Hz for special requirements.

TRANSOMIK 0.4...1.5IP54-EMC inverters incorporate a LC output filter to produce a sine-wave output voltage. The motor is practically noise-free.

Options
  • Technology assembly for ventilation industry with PID controller, modes of operation:
    • Operation with direct speed control
    • Operation with PID control:
      • Display of controlled process variable
      • Inversion of sign of measured value, e.g. to change from pressure increase to pressure decrease control
    • Control setpoint (alternatives):
      • Setpoint from integrated potentiometer
      • Control setpoint from external potentiometer or remote setpoint 
      • (0...+10 V preferred)
      • Operation with three or four selectable preset setpoints
      • Alternative operation with external potentiometer/remote setpoint or with three internal selectable preset setpoints
    • Load independent closed-loop control of volume flow with free-flow fan wheels. The volume flow is determined by processing the measured pressure in a ring pipe. 
  • Customized versions (e.g. company logo, special interfaces) for OEM requirements 
  • Bus interface to ECHELON/LonWorks in development, other bus systems available on request

Typical installations

  • Speed control of extractor fans in the catering trade
  • Speed control of fan motors in the ventilation industry (decentral installation)
  • Control of volume flow of pumps (decentral installation)
  • Speed control of conveyor belts. TRANSOMIK IP54 is mounted directly on the frame of the conveyor belt
