Notes:
Output Voltage (VDC) Output Current (Max A) Ripple
Model Effi ciency 1. Output regulation includes line & load.
Number PreSet Range Convection With & Noise (%) 2. Ripple & noise is measured from 10 Hz to 20 MHz. Connection to the unit is made with a
0.1 µF ceramic capacitor & a 22 µF electrolytic capacitor connected in parallel.
25 CFM (% p-p)
3. A 1% minimum load is required to maintain regulation & ripple specifi cations.
MPU-300MS-12YZ 12 VDC 12.0 - 13.8 12.50 25.00 ±1% 80% 4. Transient recovery is measured to within a 1% error band for a load step of 50% to 100%.
5. Isolation specifi cations are production HI-Pot tested for 3 seconds.
MPU-300MS-15YZ 15 VDC 14.0 - 16.0 10.00 20.00 ±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 range
MPU-300MS-24YZ 24 VDC 23.0 - 28.0 6.25 12.50 ±1% 80% 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
MPU-300MS-48YZ 48 VDC 44.0 - 52.0 3.12 6.25 ±1% 80%
power level is 150W without providing 25 CFM airfl ow. All models provide a peak power
level of 600W for a maximum duration of 500 µS. For more information, contact the factory.
Model Number 8. Each unit includes two 250V/5A 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. 36 VDC, etc)
