The MBC450 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 is designed and approved to the latest Medical
standards (EN/IEC 60601-1), providing 2 x MOPP isolation for Class I
& Class II applications.
These medical power supplies are ideal for monitoring, home health
equipment as well as surgical devices.

Combined output power of main output, fan supply and standby supply shall not exceed max. power rating.
Standby output voltage 5 V/ 1.5A(convection) / 2A(420LFM) with tolerance including set point accuracy, line and load regulation
is +/-10%. Ripple and noise is less than 5%.
Fan supply output voltage 12V/ 500mA with tolerance including set point accuracy, line and load regulation is +/-30% and needs
min. 1% load on main output to be within regulation band. Ripple and noise is less than 10%.
Ripple is peak to peak with 20 MHz bandwidth and 10

capacitor at rated line
voltage and load ranges. Please contact factory/ sales representative for minimum load required for ripple to be within
specification.
Specifications are for nominal input voltage, 25°C unless otherwise stated.
