Inverter fan speed controllers

Application

Inverter fan speed controllers designed for speed controllable 3 phase motors. The INV range of controllers are housed in metal enclosures. The inverters come pre-programmed and feature a stop/start switch and speed adjustment dial. As an optional extra we offer remote (not wireless) speed adjustment stations.

Composition

  • INV range of controllers are housed in metal enclosures.
  • The inverters come pre-programmed and feature a stop/start switch and speed adjustment dial.
  • When choosing the inverter please ensure that the F.L.C. of the fan motor +10% does not exceed the max rating (in amps) of the inverter. This allows (if required) the carrier frequency to be changed.

Accessories

Remote (not wireless) speed adjustment stations:
  • Remote speed adjustment station - RSAS-M
  • Remote speed adjustment station - RSAS-PC
  • Remote speed adjustment station (IP65) - RSAS-IP65

Inverters for Demand Control Ventilation [DCV]

Most ventilation systems are designed to supply ventilated air based on assumed, rather than actual, occupancy. This often results in over-ventilation, wasting both money and energy. The solution to this is Demand Control Ventilation (DCV) whereby a sensor measures the actual conditions and, when used in conjunction with a frequency inverter, the ventilation rate is automatically adjusted ensuring the building is ventilated cost effectively.

We can offer any of our inverters along with a sensor such as temperature or pressure so as to provide a controls package where a constant value e.g temperature, pressure is to be maintained.

Please enquire for details.

Order example

1Ph-3Ph inverters:
Part code is INV1-x-y where x is the kW of the fan motor and y is the actual F.L.C. of the fan motor.
Please note that on INV1 inverters the F.L.C. stated must be that at 230V 3ph.

3Ph-3Ph inverters:
Part code is INV3-x-y where x is the kW of the fan motor and y is the actual F.L.C. of the fan motor.

When choosing the inverter please ensure that the F.L.C. of the fan motor +10% does not exceed the max rating (in Amps) of the inverter. This allows (if required) the carrier frequency to be changed.

Wiring diagram 1

Operation

Installation
Check that the inverter speed controller supplied is compatible with the fan motor.

NOTE: WHEN DRILLING HOLES IN THE ENCLOSURE FOR CABLE ENTRIES THE INVERTER INSIDE THE ENCLOSURE MUST BE COVERED TO PREVENT SWARF ETC PENETRATING THE INVERTER. FAILURE TO DO THIS WILL INVALIDATE THE WARRANTY

Be sure to install the inverter in a well ventilated room that does not have direct exposure to sunlight, a tendency for high temperature,
high humidity or dew condensation, high levels of dust, corrosive gas, inflammable gas, grinding-fluid mist, salt damage, etc. Otherwise there is a danger of fire.

Allow 150mm of free space at either side of the controller for airflow movement.

Unlock the front lid of the controller using the plastic key provided. The door isolator has to be in the OFF position to open the lid. This provides access to mounting holes and electrical terminals.

*All wiring must be carried out by a suitably qualified and competent person and comply with current applicable regulations*

Operating instructions
The inverter has been programmed to suit the fan it is been used in conjunction with and therefore no programming of the inverter is required.

Turn the door isolator to the ON position
Turn the stop/start switch to the START switch
Adjust the graduated stepless speed control knob to the required speed 0=minimum speed 10=maximum speed
