Phoenix Contact 2903160 TRIO-PS-2G/1AC/48DC/10 – 48 V DC, 10 A Power Supply
The Phoenix Contact 2903160 (TRIO-PS-2G/1AC/48DC/10) is a single-phase, primary-switched DIN rail power supply from the Phoenix Contact TRIO POWER range, second generation. It delivers 48 V DC at 10 A (480 W), and the output can be adjusted from 36 to 55 V DC. A dynamic boost supplies 150% of the nominal current (15 A) for 5 seconds, giving 720 W for starting loads with high inrush current. With over 93% efficiency, AC or DC input and push-in connections, it is a strong choice for 48 V drives, motors and communication equipment in machine building.
