The PD-NPM-0305EP allows for up to ±100mV output voltage adjustment for both Output 1 and Output 2. Connecting a resistor, R
ADJ
,
between Pin 5 and Pin 1 will increase the output voltage of Output 1and Output 2. Connecting a resistor, R
ADJ
, between Pin 5 and Pin 2
will decrease the output voltage of Output 1and Output 2.

Output currents below the minimum rate may cause total regulation to divert from rated specifications. In cases where Output 1 or Output
2 is not in use, the unused output should be loaded for minimal current consumption with a resistor.
The unit is designed to meet EN55022 Class B Standard with an external EMI filter. For filter design recommendations, refer to the
PowerDsine xDSL Power Modules Application Note.
In order to comply with the EN60950 standard in telecommunication networks, the unit's input voltage must not exceed 120Vdc.
In order to comply with the EN60950 standard, the maximum operating ambient temperature must be 85
°
C.
Output ripple may reach 150mV at ambient temperatures below -10
°
C.
When the Inhibit function is not used it is recommended to permanently connect the Inhibit terminal to Vin RTN (pin 8).
