3.2.3 Power Sources

NPT-1020 platforms can be powered by DC sources complying with the applicable sections of ETSI 300
132-2 and the SELV or TNV requirements of EN 60950. The nominal supply voltage is -48 VDC (positive-lead
grounded). However, the allowed supply voltage range is -40.5 VDC to -60 VDC. Two separate DC power
sources must be available for redundancy. In the DC power supply, the maximum power consumption of
the NPT-1020 is 55 W.
For AC power supply, configure an external AC/DC converter.
