Power Supply CBA Top View

CAUTION !

Fixed voltage (or Auto voltage selectable) power supply circuit is used in this unit.

CAUTION ! : For continued protection against risk of fire,

If Main Fuse (F1) is blown , check to see that all components in the power supply

replace only with same type 5 A, 250V fuse.

circuit are not defective before you connect the AC plug to the AC power supply.

5A/250V ATTENTION : Utiliser un fusible de rechange de même type de 5A, 250V.

Otherwise it may cause some components in the power supply circuit to fail.

NOTE:

The voltage for parts in hot circuit is measured using hot GND as a common terminal.

Because a hot chassis ground is present in the power supply circuit, an isolation transformer must be used when repairing. Also, in order to have the ability to increase the input slowly, when troubleshooting this type of power supply circuit,

a variable isolation transformer is required.
