TDK Corp. has announced the introduction of a PMBus communications interface option card for the 700- to 1,500-W QM Series modular power supplies. The PMBus (Power Management Bus) option is an open standard digital power management protocol, allowing power devices to communicate with each other. The QM power supplies are available with up to 16 outputs, have full medical MoPPs isolation, and exhibit low acoustic noise.
The communications option can be selected when using the TDK-Lambda “Product Quick Finder” configuration tool. This web-based tool allows users to enter their desired output voltages and currents, select any options, and be provided with an eight-digit code for simplified quoting and ordering purposes. The program will automatically select the optimum product and configuration.
