Brief introduction of the Module Power Box
1. Module Power Box consists of the 2 Channel Class D Amplifier and the Switching Mode Power Supply (SMPS) design for use
with lifestyle micro centre unit (MZ-1000, MZ-1100 and MZ-1200).
2. A specific cable (CABLE INTERCONNECT 20P) is needed for connection between the Power Box and the centre unit in order
for the centre unit to receive supply for operation and also to implement software control to the Power Box.
3. WARNING
SMPS Board consists of high voltage filter capacitors (2203 or 2210).
Safety measures must be taken by the repair technician during servicing:
- When the supply is on, avoid touching the SMPS Board and the high voltage filter capacitors (2203 or 2210).
- When the supply is off, make sure to discharge the high voltage filter capacitors (2203 or 2210) with a suitable value resistor
before any servicing to prevent electric shock.
