Named MU4, the power supplies can accept up to five isolated regulated output boards and provide up to 800 or 600 watts depending on the input voltage (see below). The dimensions are 89 x 41 x 258 mm, which allows it to fit into a 1U rack slot.
To simplify for use in BF-rated medical applications, all models have MOPP (Patient Protective Equipment) isolation, including output -to ground. Also envisioned for use in dental, test, measurement, broadcast, professional audio, and industrial equipment.
There are four standard output module slots and one 5V 2A standby output.
