Product Description

• The MEAN WELL TDR-240-24 is a 240W three-phase industrial switching power supply engineered to provide stable 24V DC power for industrial control systems, automation equipment, electromechanical machinery, and electrical distribution cabinets.
• Part of the MEAN WELL TDR-240 Series, this single-output AC/DC power supply supports a three-phase input voltage range of 340–550V AC at 47–63Hz. The manufacturer also specifies a DC input range of 480–780V DC and supports certain dual-phase input configurations when wired according to the manufacturer's instructions.
• The power supply delivers a nominal output voltage of 24V DC with a maximum rated output current of 10A and 240W total output power. Its output voltage can be adjusted from 24V to 28V DC to accommodate compatible application requirements.
• The unit incorporates passive power factor correction and provides approximately 92% typical conversion efficiency, helping reduce power losses and heat generation during normal operation.
• Built-in protective functions include short-circuit protection, overload protection with constant-current limiting, overvoltage protection, and overtemperature protection. These features are intended to help protect the power supply and connected equipment when operated within manufacturer specifications.
• The TDR-240-24 features a slim 63mm-wide metal enclosure designed to conserve cabinet space. It mounts directly onto compatible TS-35/7.5 or TS-35/15 DIN rails and uses screw-terminal connections for electrical input, output, and signaling.
• A built-in DC OK relay contact provides a status signal that can be incorporated into compatible monitoring or automation systems. The unit uses natural air convection cooling without requiring an internal cooling fan.
• The manufacturer specifies an operating temperature range of -30°C to +70°C, subject to load derating and installation conditions. Full rated output is available within the applicable temperature and input-voltage limits specified in the manufacturer's datasheet.
• This model is intended for high-voltage industrial power distribution and is not designed for direct connection to ordinary 120V residential power. Installation should be performed by qualified personnel following the manufacturer's wiring, grounding, protection, and ventilation requirements.
