TDK Corporation (TSE 6762) announces the introduction of the TDK-Lambda brand 1U high MU4 series of AC-DC modular power supplies. The product’s very low acoustic noise is strongly desired in test and medical applications where audible disturbances need to be kept to a minimum. The modular MU4 can provide up to five isolated and regulated outputs and deliver up to 800W. All models in the MU4 series feature full MOPPs (Means of Patient Protection) isolation, including output to earth, to simplify implementation into BF-rated medical applications. Other target applications include dental, test and measurement, broadcast, professional audio, and industrial equipment.
With intelligent fan control, the MU4 fan rotation speed is reduced, producing audible noise as low as 36dBA*. Its microcontroller algorithm monitors the temperature of the primary converter and each output module, allowing the fan speed to be adjusted for optimum cooling.
The low profile, 1U high, MU4 measures just 89 x 41 x 257.5mm (W x H x D), allowing a smaller system enclosure.
Initially, nine modules are available, offering a continuous range of voltages from 3.3V to 104V with ratings from 150W to 480W. Options include a 5V / 2A standby voltage, fan fail signal, inhibit and enable (for individual or all outputs), DC good, PMBus™ communication, and current share for parallel configurations.
Configuring and selecting products from the MU4 series is extremely simple using the online Quick Product Finder, which automatically produces an optimised module selection from a wide range of options. Upon entering the desired output voltages and currents, it will automatically produce a 7-digit code to facilitate easy order placement.
