NOTES

1.

Outputs Overload 1 and Overload 2 are designed to drive 1mA for an opto-coupler LED (no additional resistor is needed). High

impedance load on this terminal may develop high voltage up to 120Vdc.

2.

Outputs Unbl. and Unbl. RTN are designed to drive 1mA for an opto-coupler LED (no additional resistor is needed). High impedance load

on this terminal may develop up to 13Vdc.

3.

Unless otherwise stated, data refers to both Output 1 and Output 2.

4.

Connecting a resistor, Rext, between pin 6 and 8 sets the output voltage. For output voltages of 110V, Rext = 11.5K

Ω resistor. When left

open (Rext =

∞), the output voltage is set to its maximum value. Setting effects both Output 1 and Output 2.

5.

The output stage acts as a current source. When output current reaches the threshold, an overload circuit will detect 5-8V drop below the

nominal set value.

6.

The output stage acts as a current source when it reaches the current limit level. When output voltage falls below a threshold level, the

output stage is disconnected in order to reduce heat dissipation. The unit reverts to normal operation once the overload condition is

removed. Overload condition on one output does not effect the other output.

7.

The module 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.

8.

When connecting the two outputs in parallel to achieve a single 120V/120mA output, automatic recovery from overload shutdown will

occur only after the total consumed output current drops below 60mA.

1.

For North America, input voltage (nominal 48Vdc, tolerance 36-60Vdc) must be applied by isolated DC source complying with the earthed

SELV or TNV requirements of the UL1950, Third edition.

For other countries, input voltage (nominal 48Vdc, tolerance 36-72Vdc) must be supplied by isolated DC source complying with the

earthed SELV or TNV requirements of the latest version of EN60950.

2.

DC input must be protected by UL Listed fuse rated maximum T2.5A, 250V (slow-blow 2.5A, 250V fuse).

3.

When applicable, protection from excessive voltage on the output should be tested in end-use equipment.
