PMBus communications for modular power supply

TDK Corporation announces the introduction of a standby/signal option with a PMBus communications interface for the QM series of 700 to 1500W modular AC-DC power supplies. The PMBus (Power Management Bus) is an open standard digital power management protocol, allowing communication between devices.

The QM series is the latest product in a 37-year legacy of modular power supplies, featuring very low audible noise and full MOPPs medical isolation. The new PMBus interface can be used to improve system-level power management. It allows the user to inhibit or enable all the QM output voltages with a single command, monitor the inlet temperature, review fan speed and status, monitor run-time and determine manufacturing related data.
