TDK Lambda DRB960-48-3-A1 DIN Rail Mount Three-Phase Power Supply
The DRB960-48-3-A1 is a DIN rail-mount three-phase power supply manufactured by TDK Lambda. This unit converts a three-phase AC input into a regulated 48 V DC output. It suits industrial automation panels that require compact and reliable DC power conversion. The power factor for the model reaches approximately 0.94 across the 400 to 500 Vac range. It also meets EN61000-3-2 Class A harmonic compliance standards for industrial equipment.
No-load power consumption in standby for this DRB960-48-3-A1 power supply stays between 2.0 W and 2.3 W. The typical cold start inrush current for the DIN rail mount three-phase power supply measures 17 A at 400 Vac and 20 A at 500 Vac. If one input phase drops, the unit still delivers up to 480 W of output power. The hold-up time at 400 to 500 Vac input remains a minimum of 20 milliseconds.
The DRB960-48-3-A1 power supply accepts a three-phase AC input voltage range of 380 to 500 Vac. The maximum AC input voltage extends to 342 through 575 Vac while remaining safety certified for 380 to 500 Vac. The input surge voltage for the model reaches 620 Vac and is sustained for five seconds. No minimum load is required for stable operation of the power supply. The maximum load capacitance supported by the model reaches up to 20,000 microfarads in total. The average efficiency for the power supply reaches around 95.2 percent at 400 Vac input voltage.
The DRB960-48-3-A1 three-phase power supply supplies a regulated 48 V DC output with a voltage tolerance of plus or minus 3 percent. The line regulation for this power supply remains as low as 0.01 percent across input changes. The load regulation outside parallel operation for the model stays close to 0.2 percent. An external DC fuse allows it to accept a 450 to 810 VDC input range. The input frequency tolerance for this power supply spans a range of 47 to 63 Hz. The maximum input current per phase and on DC input each reach 2.2 A under full load.
