Phoenix Contact 2866789 QUINT POWER Supply – 960W 24V 40A for Industrial Automation

Description

Application Scenarios

A large automotive manufacturing plant operates multiple robotic assembly lines, each controlled by a network of PLCs, servo drives, and safety relays. The plant’s electrical maintenance team faced a recurring issue: standard power supplies were failing to trip upstream circuit breakers quickly enough during fault conditions, resulting in cascading power failures that halted entire production lines.

The solution was installing Phoenix Contact 2866789 QUINT POWER supplies at each control cabinet. Unlike conventional power supplies, the Phoenix Contact 2866789 delivers up to six times its rated current for 12 milliseconds through SFB technology, magnetically tripping standard miniature circuit breakers almost instantaneously . When a short circuit occurred on one assembly line’s 24 V DC distribution, the Phoenix Contact 2866789 isolated the fault without affecting adjacent lines’ power supply.

The maintenance team also noted that the POWER BOOST feature of the Phoenix Contact 2866789 provided up to 1.5 times the nominal current (45 A) continuously, enabling reliable startup of high-inrush loads such as motor brakes and capacitive input filters without voltage dips . The plant reported a significant reduction in unplanned downtime and simplified troubleshooting due to the supply’s preventive function monitoring, which signals critical operating states before failures occur .
