Notes:
For heatsink option, add suffix “H” to model number (i.e.
MB5012S-05RW-H)
1. Start up time is measured at nominal input and with a constant resistive load.
2. When measuring output ripple, it is recommended that an external 1 µF capacitor and 10 µF capacitor be connected in parallel from the +V
OUT
to the -V
OUT
pins.
3. Transient recovery is measured to within a 1% error band for a load step change of 25%.
4. Short circuit protection is provided by a “hiccup mode” circuit.
5. The switching frequency for 24 VDC output models is 285 kHz.
6. Operation at no-load will not damage these units.
7. It is recommended that a fuse be used on the input of a power supply for protection. See the Model Selection table above for the correct rating.

An external resister may be added to adjust the converter
output.
To adjust the output UP, connect a 5%, 3W resistor between
the minus output pin (5) and the Vout trim pin (6). To adjust
the output DOWN, connect a 5%, 3W resistor between the plus
output pin (4) and the Vout trim pin (6).
The trim table at right gives suggested resistor values for
this adjustment.
