Having both medical and industrial safety certifications, the QM8 addresses a wide range of applications, including BF rated medical equipment, test and measurement, broadcast, communications and renewable energy applications.
The QM series operating efficiency is up to 91%, reducing internal heat losses, allowing the use of low speed, low audible noise fans for cooling.
This provides an enhanced patient/user experience and increased reliability. The QM series is covered by a seven-year warranty.
Accepting a wide range 90-264Vac 47-440Hz input, the QM8 can deliver between 1200W to 1500W output power.
Available output voltages range from 2.8V to 105.6V and up to eight single or dual modules can be fitted.
Optional standby/signal modules can be specified with a choice of one or two standby voltages (5V, 12V and 13.5V at up to 2A), a PMBus communication interface and unit inhibit or unit enable, and an AC Good signal.
The units can operate in ambient temperatures of -20 to +70°C, derating output power and output current by 2.5% per °C above 50°C. Overall case dimensions are a compact 200 x 63.5 x 270mm (W x H x D), and the weight is between 2.3 to 3.4kg, depending on the module configuration.
The QM series is certified to IEC/EN/UL/CSA 60601‑1, ANSI/AAMI ES 60601‑1, IEC/EN 61010‑1 and IEC/EN/UL/CSA 60950‑1 with CE marking for the Low Voltage, EMC 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 QM8 has a maximum earth leakage current of 300µA, 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 EN 60601‑1‑2 and EN 61000‑6‑2 immunity standards.
An online configurator makes product selection extremely simple, giving an optimised module selection with a choice of signals, leakage current and standby voltages.
Upon entering the desired output voltages and currents, the configurator will automatically produce a short 7‑digit code for easy order placement and quick dispatch.
Avnet Abacus receives Senten Manten Gold Award by TDKAvnet Abacus, one of Europe’s leading interconnect, passive, electro-mechanical and power distributors and a regional business unit of Avnet (, is the recipient of TDK Corporation’s 2017 European Senten Manten Gold award.
This recognition comes as a result of the consistently strong operational and sales performance achieved by Avnet Abacus, with 17.6% sales growth year on year gained across the TDK product range.
The annual awards are based on TDK’s annual Senten Manten distributor performance evaluation programme.
The Japanese term, Senten Manten, stands for the perfect result, with a maximum of 1000 points available.
Distributors are assessed on performance and collaboration with TDK in four categories: business performance, inventory management, contractual terms, and operational excellence.Avnet Abacus was awarded the top score of 830 points across the categories.
Nigel Ward, president of Avnet Abacus, commented: “This is a great accolade that exemplifies the strength of our long-term engagement with TDK. TDK continues to be a key technology partner working in collaboration with our technical teams to deliver the very best product solutions to customers across Europe.”
Dietmar Jaeger, head of TDK’s distribution business in Europe and vice president of global sales distribution, added: “We have an excellent relationship with Avnet Abacus on all management levels. This award fully endorses the successful efforts of their teams, which have resulted in high class technical support to customers across our product range.”
