Product Description

• The MEAN WELL TDR-960-24 is a 960W three-phase industrial AC/DC switching power supply designed to deliver a stable 24V DC output for automation systems, industrial machinery, process control equipment, electrical panels, and other high-current DC applications.
• Part of the MEAN WELL TDR-960 Series, this single-output power supply operates from a three-phase AC input range of 340–550V AC at 47–63Hz. It also supports a 480–780V DC input and certain dual-phase operating configurations subject to the manufacturer's wiring requirements and output derating specifications.
• The TDR-960-24 provides a nominal 24V DC output with a maximum rated current of 40A and total output power of 960W. The output voltage can be adjusted from 24V to 28V DC for compatible equipment and control system applications.
• Active power factor correction and approximately 94% typical conversion efficiency help reduce electrical losses. The power supply uses natural air convection for cooling, eliminating the need for an internal cooling fan.
• Built-in protection features include short-circuit protection, overload protection with constant-current limiting, overvoltage protection, and overtemperature shutdown. These functions support operation within the manufacturer's specified electrical and environmental limits.
• A built-in DC OK relay contact provides a status signal for integration with compatible monitoring and automation systems. The manufacturer also supports current sharing between compatible TDR-960 power supplies, allowing appropriately engineered parallel installations with system output capacity of up to 3840W in a 3+1 arrangement.
• The metal enclosure measures 110mm wide, 125.2mm high, and 150mm deep. It installs on standard TS-35/7.5 or TS-35/15 DIN rails and uses terminal connections for input power, DC output, and signaling.
• The manufacturer specifies an operating temperature range of -30°C to +70°C, with output power derating required under certain temperature, input voltage, and installation conditions.
• This is a high-voltage industrial power supply requiring the appropriate three-phase AC or high-voltage DC source. It is not intended for direct operation from a standard 120V residential wall outlet.
• Electrical installation, grounding, circuit protection, and power supply configuration should be performed by qualified personnel in accordance with MEAN WELL's installation instructions and applicable electrical standards.
