700 to 1200W Modular Power Supplies Have BF Ready Isolation and Low Acoustic Noise

San Diego, CA – August 2017 –

TDK Corporation announces the introduction of the QM5 modular power supplies, rated at 700 to 1200W.  These models are available with up to 12 outputs, have BF ready isolation and low acoustic noise.  With medical and industrial safety certifications, the power supplies are suitable for use in medical, test and measurement, communications and broadcast equipment.

Accepting a wide range 90 to 264Vac, 47-440Hz input, the QM5 can deliver 700W at low line and 1200W with a 150-264Vac input.   With its modular construction, the series can be configured using a simple on-line configurator to provide 1 to 12 independently regulated outputs and include individual output good signal and remote on/off functions.  Module output voltages range from 2.8V to 52.8V and output powers from 300W to 1200W.  A further subset of option modules provides an AC Fail signal, standby voltages (up to 12V 2A), global remote on/off and PMBus™ communications.  Overall case dimensions for the QM5 are 127 x 63.3 x 270mm (W x H x D).

The QM5 will operate in ambient temperatures of -20 to +70°C, with output power and output current linearly derating above 50°C to 50% at 70°C. With efficiencies of up to 91%, less internal heat is generated allowing the use of a low speed cooling fan to reduce audible noise.  A lower airflow speed also significantly reduces the ingress of dirt and other contaminants, improving product reliability.  All models in the QM series have a seven-year warranty as standard.

The power supply has 4,000Vac (2 x MoPPs) input to output, 1,500Vac (1 x MoPPs) input to ground and 1,500Vac (1 x MoPPs) output to ground isolation.  All models are certified to IEC/EN/UL/CSA 60601-1, ANSI/AAMI ES 60601-1, IEC/EN/UL/CSA 60950-1 and are designed to meet IEC/EN61010-1 with CE marking for the Low Voltage and RoHS2 Directives.  Earth leakage current is less than 300µA for the QM5, and complies 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 and are designed and manufactured under the control of ISO9001 and ISO13485 (including risk management).
