ECAC technology

What exactly is ECAC technology?

 When PSC Motor and Fan describe their range of ECAC products, we use the acronym “ ECAC ,” to refer to an electric motor, fan, blower or impeller that is powered by E lectronically C ommutated A lternating C urrent.

This means that the power to the unit comes out of the available power socket; this is 115V AC in the US and 230V AC in Europe and Asia.

Each PSC ECAC Motor is equipped with sophisticated on-board Voltage Conversion Circuitry that converts the 115V AC or 230VAC power input to 90V 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 is PWM 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 A T achometer Out Signal is provided, so that the User can monitor the performance of the motor. This signal usually provides 3 Pulses per Revolution.

l An Alarm Signal can also be available which tells the User if the Motor has stopped for some other reason.

The major advantage of ECAC technology, as compared to a straight AC-powered electric motor, is the Power Savings .

As an example, a standard 225mm AC Impeller may consume 160 Watts in power, whereas an equivalent 225mm ECAC Impeller may consume only 108 Watts in power, thereby using 62 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 by PSC Motor and Fan , will see on average a drop in power consumption of at least 30 per cent over an equivalent conventional AC powered unit.
