Power Adapter MEAN WELL TDR-240-48 240W 48V Input 340-550V

The MEAN WELL TDR-240-48 is an industrial AC-DC three-phase DIN-rail power supply with active PFC and constant current functionality. It provides a 48 V DC output at up to 5 A (240 W total) and accepts a high input range of 340–550 V AC. The unit includes a DC OK signal for system monitoring and is RoHS compliant. Its compact housing (63 mm × 113.5 mm × 125.2 mm) fits standard DIN-rail installations in control cabinets and industrial equipment.

Advantages

The TDR-240-48 offers stable 48 V DC output with constant-current capability and active power factor correction for improved efficiency and lower harmonic distortion. Its wide input voltage range makes it suitable for three-phase industrial supplies. The DC OK indicator enables easy status monitoring, and the compact DIN-rail form factor simplifies mounting and space management in electrical panels.

Suitable for

• Industrial control cabinets and automation systems
• DIN-rail mounted power distribution for machinery
• Systems requiring 48 V DC at up to 5 A with monitoring
