Product Description:
The leading producer Sanyo Denki’s variant PBM423DXC60 is sourced from its latest PB SANMOTION Servo Motors product line for high power drive control. It serves as a three-phase bridge rectifier module supplied from AC to DC in servo applications. The diode is rated at sustained maximum reverse peak diode integrity up to 1600 volts. On average, the motor’s forward current is 425 A and it supplies sustained DC power for servo drives.
This SANMOTION module endures surge peak forward currents up to 8000 A which accommodates inrush currents during start-up. It exhibits a typical forward voltage drop of 1.15 V per element and minimizes conduction losses. The device isolates at 3000 V AC per minute, protecting control electronics from high-voltage spikes. The unit mounts via screw mount style and thus ensures secure installation in power racks. It operates from –40 °C to +150 °C jus to maintain performance across engine-room extremes. The variant houses a module-style case for further simplifying heat-sink integration. It mass is about 650 g which eases manual mounting mechanism.
This industrial motor PBM423DXC60 measures 145 mm × 62 mm × 40 mm that allows standard power-module footprints. It requires terminal torque of 2.5 Nm for a secure and reliable electrical contact under vibration. It also omits specified reverse recovery time which aligns with slow-recovery bridge behavior for smoother waveforms. The module delivers up to 81.2% conversion efficiency and further reduces power dissipation and heat generation. Furthermore, it features a junction-to-case thermal resistance of 0.2°C/W, guaranteeing manageable temperature rise under heavy loads. The PBM423DXC60 balances rugged electrical performance and compact dimensions for robust servo-drive rectification.
