Notes:
1. Ripple and noise are measured at 20 Mhz
bandwidth with a 0.1µF and a 47 µF capacitor
connected in parallel as close to the unit output
terminals as possible.
2. Output short circuit protection is provided by a “hiccup
mode” circuit. The unit recovers automatically when
the fault condition is removed.
3. Operation at under no load conditions will not damage
these units.
4. It is recommended that a fuse be used on the
input of a power supply for protection. For the
MPM-20PB series, a 2A/250 VAC slow blow
should be used.
