Notes:
1. Load regulation is measured for an output change of 10% to 90% at nominal input
line. For multiple output models, the loads are balanced.
2. As shown in the connection diagram at right, a simple external circuit may be used to
adjust the power supply output
±10%.
To adjust the output DOWN, connect a 5%, 3W resistor
between the plus output pin and the Vout trim pin. To adjust the output UP, connect a 5%, 3W
resistor between the minus output pin and the Vout trim. Contact the factory for resistor values
needed to achieve a specific output.
3. It is recommended that a fuse be used on the input of a power supply for protection.
For the
MPM-20S
series, a 3.15A/250 VAC slow blow should be used.

Notes:
1. C1 is a high frequency, low resistance electrolytic capacitor. Refer to the suppliers specifications
for capacitance/current ratings.
2. Voltage derating on all capacitors should be 80% or higher.
3. C2 eliminates high frequency noise.
4. The power supply includes an internal TVS. If the user requires a tighter OVP threshold, an external
TVS may be connected as shown.
