TDK Corporation announces the introduction of a standby\/signal option with a PMBus\u2122 communications interface for the QM series of 700 to 1500W modular AC-DC power supplies<\/a>. The PMBus\u2122 (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\u2122 interface can be used to improve system-level power management in medical equipment, test and measurement, broadcast, communications and renewable energy applications.<\/p>\n

\"\"<\/a><\/p>\n

The PMBus\u2122 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. Up to 8 units can be connected to a single PMBus\u2122 controller. The standby\/signal option also contains a 5V\/2A standby voltage (always present when AC power is applied to the power supply), and a fan-fail warning signal indicating that a fan has stopped, is slowing down or running too fast indicating a blockage.<\/p>\n

The interface option is selectable during the initial configuration of output voltages and current using the on-line program from the TDK-Lambda UK website. The configurator makes product definition very easy, providing an optimised module selection for the desired output requirements.<\/p>\n

The QM series is certified to IEC\/EN\/UL\/CSA 60601-1, ANSI\/AAMI ES 60601-1, IEC\/EN 61010-1, IEC\/EN\/UL\/CSA 60950-1 with CE marking for the Low Voltage and RoHS2 Directives. With an input to output isolation of 4,000Vac (2 x MOPPs), 1.500Vac input to ground (1 x MOPP) and 1,500Vac (1 x MOPP) output to ground, the series can be used in BF rated medical equipment. The QM range has a maximum earth leakage current of 300\u00b5A, while still complying with the EN61000-6-3:2007 and EN60601-1-2:2015 (curve B conducted and radiated) emission standards. The units also meet the EN60601-1-2 and EN61000-6-2 immunity standards.<\/p>\n
