The MBC300 Series of open-frame medical power supplies, with its
wide universal 90-264 VAC input range, is available at 300 W of output
power and a variety of single output voltages.
The MBC series was designed to 4th edition medical approvals and
provides 2x MOPP (Means of Patient Protection) isolation for Class I
and Class II installations.
These medical power supplies are ideal for monitoring, home health
equipment as well as surgical devices.
