Functions Mode

    • Master – automatic controller:
      the control can be programmed to operate in two different modes:
      • PID with "IES" technology to maintain the controlled variable (eg temperature, pressure) at the set value (set-point)
      • P (Proportional) to maintain the controlled variable (eg temperature, pressure) within the proportional band.
    • Slave Unit:
      the fans regulation changes directly/inversely to the incoming signal/s.
The regulation can be Direct (DIR) or Reverse (REV).

What's

DSV is an electronic three-phase digital controller, made from the hybrid-power technology based on voltage steps, the first completely free from extra-noise (electrical, electromagnetic and acoustic), coming from the electronic regulation of fans motors with phase cutting (VAC) or frequency (HZ) regulation.
With this type of step controller, the effective voltage applied to the fans motors varies between fixed values: the steps provided on the autotransformer and the asynchronous motor.
This type of regulation is perfectly sinusoidal (constant frequency), and can always be applied to fans motors without:
  • special wiring shielded cables
  • EMC filters
  • LHC filters for harmonic distortion (THD%)
  • filters for motor protection from micro-waves
  • insulation transformer
    The DSV controller generated NO-noise disturbance during the adjustment of the fan speed.
    The controller integrates the control software to regulate the adiabatic system mounted on the ventilated heat exchanger, simply by setting the dedicated set point and proportional band.
    Using Modbus serial connection, you can connect to the DSV the innovative software CLIMA-Sinergy designed to interact with SELPRO regulators and ventilation systems.
    The Clima-Sinergy allows to collect operating data, analyze and modify the parameters to optimize the system performance.

    Applications

    Particularly suitable for plants that require a high degree of conformity for electrical and sound noises, as:
  • hospitals
  • research centers
  • EDP / EDV
  • telecom centers
  • residential applications
    The ease of installation and the high degree of conformity with all types of fans motors, are the ideal for operations on systems that show after sale problems
