San Diego, CA - November 2019
TDK Corporation (TSE 6762) announces the introduction of the TDK-Lambda brand QM8B modular power supplies rated at up to 2000W. This further extends the QM series which can provide 550W to 2000W output power. The QM8B models are available with up to 18 outputs, have full MoPPs (Means of Patient Protection) 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. This avoids the need for multiple power supplies in systems requiring a large number of independent voltages.
Accepting a wide range 90 to 264Vac, 47-63Hz input (440Hz with reduced PFC), the QM8B can deliver 1200W at low line and 2000W with a high line 180-264Vac input. With its modular construction, the series can be configured using a simple on-line configurator to provide 1 to 18 independently regulated outputs and include individual output good signal and remote on/off functions. The QM series module output voltages range from 2.8V to 105.6V and have output power levels from 300W to 1200W. A further subset of option modules provides an AC Fail signal, standby voltages (up to 12V, up to 2A), global remote on/off and PMBus™ communications. Overall case dimensions for the QM8B are 200 x 63.3 x 268mm (W x H x D).
The QM8B will operate in ambient temperatures of -20 to +70°C (-40°C start-up), 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 low speed cooling fans 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 MoPP) input to ground and 1,500Vac (1 x MoPP) output to ground isolation. All models are certified to the IEC/EN/UL/CSA 60601-1, ANSI/AAMI ES 60601-1 and IEC/EN/UL/CSA 60950-1 safety standards. The QM series is also designed to meet IEC/EN 61010-1 with CE marking for the Low Voltage, EMC and RoHS Directives. Earth leakage current is less than 300µA, and complies with the EN 61000-6-3:2007 and EN 60601-1-2:2015 (curve B conducted and radiated) emission standards. The units also meet the EN 60601-1-2 4th edition and EN 61000-6-2 immunity standards and are designed and manufactured under the control of ISO 9001 and ISO 13485 (including risk management).
