Power Supply Unit for CNC Control – HEIDENHAIN 236 484 10
The 236 484 10 is a multi-rail switching power supply unit for CNC control systems (“Power Supply Unit”) manufactured by HEIDENHAIN (Dr. Johannes Heidenhain GmbH, Traunreut, Germany). The module converts mains voltage into stabilised multi-rail DC output (±15 V, +5 V, +24 V typical), distributed to logic boards, encoder interfaces and I/O modules inside the control unit. The part is documented as a component of HEIDENHAIN TNC-series analogue–digital CNC controls (typically TNC 155, TNC 360 and derivatives) and coeval measuring systems and digital readouts. The product belongs to the power supply line from the 1980s–1990s generation; no publicly documented revision variants are known.
The power supply is the energy core of the CNC control: without stable, noise-free supply voltages no logic board, encoder interface or I/O module can operate correctly. A power supply failure typically manifests as a complete control lockout, undiagnosable system errors, spontaneous resets or corrupted measurement data. Replacement with a genuine HEIDENHAIN module is the only intervention that guarantees full restoration of machine functionality.
HEIDENHAIN (Dr. Johannes Heidenhain GmbH) is a German company founded in 1948 in Traunreut (Bavaria), a world leader in precision measurement systems (linear encoders, rotary encoders, optical measuring scales) and TNC-series CNC controls, the de facto standard for precision milling and grinding. All products belonging to this generation are legacy / discontinued: no longer available new from the manufacturer and sourced exclusively as used stock, NOS (new old stock) or through specialist repair services.
