Features and benefits:

• 12 V DC output - rare in industrial PSUs; suited to legacy automotive-grade controls and 12 V sensor loops
• Auto-range 120/230 V input - global single-phase infeed flexibility
• 20 ms mains buffering - ride through brief line dips without output collapse
• 40 A short-term overload - tolerates inductive load inrush
• "12 V OK" signaling via NO relay contact - direct PLC health monitoring
• Adjustable 11.5-15.5 V - compensate cable voltage drop or charge sealed lead-acid batteries
• 168 W in DIN-rail format - dense power for compact control panels

Applications:

• 12 V DC supply for legacy controls, automotive-derived ECUs and instrumentation
• Sensor / measurement loops requiring tight 0.1 % regulation
• Battery-backed control circuits (charging sealed lead-acid via the 13.8-14 V adjustable output)
• Industrial control panels needing 1-phase AC infeed and 12 V DC at up to 14 A
