150W 12V DC Switching Power Supply – COSEL LDA150W-12
The LDA150W-12 is a single-output 12 V DC / 12.5 A industrial switching power supply (“Switching Power Supply”) manufactured by COSEL, belonging to the LDA150W series. The part number encodes the nominal output power of 150 W and the regulated output voltage of 12 V DC. The input is universal AC (85–264 V AC, 47–63 Hz), compatible with both 110 V and 230 V mains without manual range switching. The unit is designed for panel or DIN-rail mounting inside electrical cabinets and is widely used as an auxiliary power supply in CNC control systems from various manufacturers (Fanuc, Mitsubishi Electric, Mazak, Okuma, and others). The alternative commercial part number is listed exclusively in the technical table below.
The auxiliary power supply converts mains voltage into stable DC voltage, which is essential to power the CNC’s control logic, I/O modules, encoders, position sensors, operator panel, and safety circuits. A failure or output voltage drift produces erratic machine behaviour or shutdowns that are particularly difficult to diagnose, since symptoms typically appear intermittently — position errors, unexpected resets, random alarms — before the unit fails completely.
COSEL Co., Ltd. is a Japanese switching power supply manufacturer founded in 1969 and headquartered in Toyama, Japan, specialised in high-reliability power solutions for industrial, medical, and telecommunications applications. COSEL products are internationally recognised for their high build quality, long service life, and compliance with major international certifications (UL, CE, TÜV). The company remains active and independent; however, certain older revisions or series may be legacy / discontinued — it is advisable to verify availability of the specific part number with an authorised distributor before ordering.
