When Machines Need a Reliable Bodyguard
In a bustling automotive assembly plant in Stuttgart, 17 production lines suddenly halted last April due to repeated relay failures. This $2.3M/hour downtime nightmare ended when engineers replaced traditional electromechanical relays with CHORDN AS14 50A 690V modules – the system has now operated flawlessly for 14 months and counting.
The Muscle Behind Modern Automation
Unlike conventional relays that wear out after 100,000 cycles, the AS14’s solid-state design delivers 10M+ operations without degradation. Its 690V rating handles Europe’s strict 400V三相 systems with 71% voltage headroom, while the 50A capacity supports 3-phase motor loads up to 22kW. The 14×51mm footprint (38% smaller than comparable models) solves spatial challenges in control cabinets.
Wind Farm Application Spotlight
At Denmark’s Anholt Offshore Wind Park, 111 AS14 units manage pitch control systems across Siemens 3.6MW turbines. Exposed to salt spray and -25°C winters, they’ve maintained 99.998% uptime since 2020 – outperforming the site’s original relays by 400% in lifespan.
Thermal Management Breakthrough
CHORDN’s patented HeatSpreader™ technology keeps junction temperatures below 85°C even at full load. Third-party tests show 22% lower thermal resistance than industry average, enabling continuous 45A operation without heatsinks. The integrated RC snubber reduces voltage spikes by 68%, protecting sensitive PLCs in packaging machinery.
‘We’ve reduced maintenance costs by €120,000 annually across our bottling plants’ – Marco Ricci, ABB Systems Integrator
Future-Proofing Industry 4.0
With IoT readiness through built-in current monitoring pins, the AS14 feeds real-time data to predictive maintenance systems. A major paper mill in Finland uses this feature to detect bearing wear 3 weeks before failure, preventing unplanned shutdowns.
