CNC Power Supply Unit – Mitsubishi PD14C-1
The PD14C-1 is a CNC control power supply module (“CNC Power Supply Unit”) manufactured by Mitsubishi Electric, belonging to the component family for the MELDAS series CNC control systems. The module generates and distributes the regulated DC voltages required by logic boards, I/O modules, and axis drive circuits within the CNC controller. The commercial alternate part number is PD14C-1 (internal item code: PD14C1). The unit is designed for rack or panel mounting inside the machine tool electrical cabinet.
The power supply is the component that converts the AC mains voltage into the regulated DC rails that all CNC electronic boards depend on. A failure — even partial, on a single output rail — can cause loss of safety logic, axis lockout, or a complete failure to boot, taking the machine entirely out of service. Output stability directly affects the accuracy of the analogue references sent to the drives and, consequently, the dimensional accuracy of machined parts.
Mitsubishi Electric is one of the world’s leading manufacturers of CNC systems, industrial inverters, and servo drives, with over 50 years of presence in motion control. The MELDAS division has equipped tens of thousands of machine tools worldwide; components from older series are legacy / discontinued and available only as used spare parts, NOS surplus, or through specialist repair services.
