4 PCB Power Module used for level 2-3 (position 014A)

Power module is intended as a module PCB for mainly vacuum cleaners from Electrolux Floor Care

& Small Appliances AB. The module is intended to consist of a Triac, triggering a motor, and a power supply

for additional connected electronic.

The component layout for the power module should look like below sketch:

1. Power Module PCB.

2. Connector main voltage

3. Alternative main power connector / main power out

4. Motor connector

5. Connector to control PCB

All different kinds of Power modules have the same configuration of connector configuration, simplifying

design, service and cross over.

To be able to control the power module a control unit is connected to the 5-pol connector, which also

power supplies the control unit with 5VDC.

The configuration for the connector is following:

1. Ground.

2. 5VDC, maximum current according to level of power module.

3. Zero cross signal, square wave that follows the main frequency (5V amplitude).

4. Reserved for TCO signal (temperature control signal). Not implemented on the PCB, only

reserved for the function.

5. Triac ignition signal from the control unit to the power module.

The high current power module consists of a switched power supply for providing the logical voltage

with higher current output.
