Notes:
Output Voltage (VDC) Output Current (A) Ripple 1. Output regulation includes line & load.
Model Effi ciency 2. Ripple & noise is measured from 10 Hz to 20 MHz. Connection to the unit is made with
Number PreSet Range Convection With & Noise (%) a 0.1 µF ceramic capacitor & a 22 µF electrolytic capacitor connected in parallel.
23 CFM (% p-p) 3. A 1% minimum load is required to maintain regulation & ripple specifi cations.
4. Transient recovery is measured to within a 1% error band for a load step change of
MPU-400CS-12YZI 12 VDC 12.0 - 15.0 20.83 33.33 ±1% 80% 50% to 100%.
5. Isolation specifi cations are production HI-Pot tested for 3 seconds.
MPU-400CS-24YZI 24 VDC 22.0 - 30.0 10.41 16.66 ±1% 80% 6. The full output range (see table) is covered in the safety agency certifi cation. Standard
models are factory set to the Preset voltage, but may be set to other levels within the
MPU-400CS-48YZI 48 VDC 42.0 - 58.0 5.20 8.33 ±1% 80% range without affecting the agency certifi cation. For more information, contact the
factory.
7. Output power is given for the factory preset voltage. The maximum continuous output
Model Number power level is 400W with 23 CFM airfl ow. All models provide a peak power level of
700W for a maximum duration of 500 µS. For more information, contact the factory.
8. Each unit includes two (250V/8A) fuses. Since these fuses are 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.
Models with other output voltage levels
are available (i.e. 5 VDC, 36 VDC, etc)
