Notes:
1. Load regulation is measured for an output change of 10% to 90% at Derating Curve
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-25 series, a 3.15A/250 VAC slow blow should
be used.

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