Number PreSet Range (Max. A) (% p-p) (%) 2. Ripple & noise is measured from 10 Hz to 20 MHz. Connection to the unit
is made with 0.1 µF ceramic & 22 µF electrolytic capacitors connected in
MPU-250S-12yF 12 VDC 11.0 - 13.8 20.83 ±1% 80% parallel.
MPU-250S-15yF 15 VDC 14.0 - 15.5 16.66 ±1% 80% 3. Transient recovery is measured to within a 1% error band for a load step
change of 50% to 100%.
MPU-250S-24yF 24 VDC 21.0 - 26.0 10.42 ±1% 80%
4. Isolation specifi cations are production HI-Pot tested for 3 seconds.
MPU-250S-48yF 48 VDC 44.0 - 52.0 5.21 ±1% 80% 5. The full output range (see table) is covered in the safety agency certifi cation.
Standard models are factory set to the “Preset” voltage. This may be set
Model Number to other levels within the range without affecting the agency certifi cation.
For more information, contact the factory.
6. Output power is given for the factory preset voltage. The maximum con-
tinuous output power level is 300W. All models provide a peak power level of
600W for a maximum duration of 500 µS. For more information, contact the
factory.
7. Each unit includes an input fuse (250V/8A). Since this fuse is not fi eld
replaceable, it is recommended that an external fuse of the same size be
used on the input of the power supply for protection.
Mechanical Dimensions Models with other output voltage levels
are available (i.e. 5 VDC, 30 VDC, etc)
