TDK 700- to 1,200-W supplies have BF-ready isolation
TDK Corp. has announced the introduction of the QM5 modular power supplies, rated at 700 to 1,200 W. These models are available with up to 12 outputs, have BF-ready isolation, and feature 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.
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 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 4,000-VAC (2 x MoPPs) input-to-output, 1,500-VAC (1 x MoPPs) input-to-ground, and 1,500-VAC (1 x MoPPs) output-to-ground isolation. All models are certified to IEC/EN/UL/CSA 60601-1, ANSI/AAMI ES 60601-1, and 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 300 µA for the QM5, and it 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 ISO 9001 and ISO 13485 (including risk management).
