Original Roland VP-540 / SP-540V / EGX-600 / MDX-540 Power Unit ZWS150PAF – 12429114

Part number 12429114 is the POWER UNIT,ZWS150PAF-36/J, a power supply unit that Roland uses in both printers and milling equipment. It fits the VersaCAMM VP-300 and VP-540 and the SP-300, SP-300V and SP-540V printer/cutters, the EGX-400 and EGX-600 engravers, the MDX-40, MDX-40A, MDX-540 and MDX-540S milling machines and the JWX-10 jewellery milling machine. This is a genuine, original Roland part – not a copy or compatible replacement.

The unit converts mains AC into the DC supply used by the machine's control and drive electronics. When it fails, the machine may not switch on, may stop during initialisation, may reset or cut out during a print or milling job, or may report motor and spindle-related errors that come and go. Heat, a burnt smell or clicking from the unit confirm that it should be replaced. Because one part covers printers, engravers and milling machines, it is a practical spare for multi-machine workshops.
