For more information, contact the factory: sales@micropowerdirect.com 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.

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.
