ECAC Technology

ECAC Technology

WhenPSC Motor and Fandescribes their range ofECAC products, we use the acronym “ECAC,” to refer to an electric motor, fan, blower or impeller that is powered byElectronicallyCommutatedAlternatingCurrent.

This means that the power to the unit comes out of the available power socket; this is **5V AC in the US and **0V AC in Europe and Asia.

EachPSC ECACMotor is equipped with sophisticated on-board Voltage Conversion Circuitry that converts the **5V AC or **0VAC power input to *0V DC power, and it is this current that actually powers the Motor.

As the motor itself is now actually powered by DC input, we can now incorporate the standard DC Motor functionality that would not be available with a standard AC powered unit.

This functionality includes the following features:

l The biggest benefit isPWM Speed Control or Analog Speed Control. This allows the User to vary the RPM of the motor to whatever speed is needed by his system; with a standard AC motor, it has to run at maximum speed at all times.

l ATachometer Out Signalis provided, so that the User can monitor the performance of the motor. This signal usually provides 3 Pulses per Revolution.

l AnAlarm Signalcan also be available which tells the User if the Motor has stopped for some other reason.

The major advantage ofECAC technology, as compared to a straight AC-powered electric motor, is thePower Savings.

As an example, a standard **5mm AC Impeller may consume **0 Watts in power, whereas an equivalent **5mmECACImpeller may consume only **8 Watts in power, thereby using*2 per cent as much power as the AC unit.  

ECAC powered electric motors, and by extension the full range of ECAC air moving devices manufactured byPSC Motor and Fan, will see on average a drop in power consumption of at least *0 per cent over an equivalent conventional AC powered unit.
