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
Number PreSet Range Convection With & Noise (%) with 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
MPU-400MS-12YI 12 VDC 12.0 - 15.0 20.83 33.33 ±1% 80% of 50% to 100%.
5. Isolation specifi cations are production HI-Pot tested for 3 seconds.
MPU-400MS-24YI 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
MPU-400MS-48YI 48 VDC 42.0 - 58.0 5.20 8.33 ±1% 80% the 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
Model Number output 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)
