TDK-LAMBDA AMERICAS PMBus communications interface option card for the 700 to 1500W rated QM series of modular power supplies is an open standard digital power management protocol, allowing power devices to communicate with each other. QM power supplies are available with up to 16 outputs, have full medical MoPPs isolation and low acoustic noise. The addition of PMBus allows the user or system to remotely turn the QM power supplies on and off (inhibit or enable mode), read back their incoming air temperatures, total operating hours, fan speed, fan status and manufacturing details. http://www.us.tdk-lambda.com
