Modular power supplies offer up to 18 outputs with low acoustic noise and full MoPPs isolation

electropages | 13/07/2020

TDK Corporation has introduced the 2000W rated QM8B series of AC/DC power supplies with the ability to provide up to 18 outputs. This further extends the series to now cover 550W to 2000W. Like all the models in the series, the QM8B features low acoustic noise and complete MoPPs isolation. With both medical and industrial safety certifications, the device satisfies a broad range of applications, incorporating BF-rated medical equipment, test and measurement, broadcast, communications and renewable energy.

TDK

Accepting a broad range 90-264VAC 47-440Hz input, the series can deliver 1500W output power or 2000W with a high line input of 180-264VAC. Offered output voltages cover 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 selection 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 work in ambient temperatures of -20C to +70C, derating output power and output current by 2.5% per C above 50C. Overall case dimensions are a compact 200mm x 63.3mm x 268mm (W x H x D), and the weight is between 2.3kg to 3.4kg, depending on the module configuration.
