When Precision Meets Power
In the heart of a bustling manufacturing plant in Shenzhen, engineers faced persistent shutdowns caused by voltage spikes in their CNC machinery. The culprit? Outdated relays that couldn’t handle sudden 850V surges. Their solution came in the form of Holly’s HC10AR 11A AR 1000V – a decision that reduced equipment downtime by 73% within six months.
Designed for Extreme Conditions
What makes this 11A-rated relay stand out? Laboratory tests show:
- 1.2 million mechanical operations at full load
- Arc extinction time reduced to 2.8ms (35% faster than industry average)
- Stable performance from -40°C to +85°C
These specs translate to real-world reliability. Take the case of Shanghai Metro’s power subsystem upgrade – after replacing 2,400 legacy relays with HC10AR units, maintenance intervals extended from 3 months to 18 months.
Smart Grid Revolution
With China’s smart grid market projected to reach $32.4 billion by 2026 (CAGR 8.1%), Holly’s engineers optimized the HC10AR for modern energy systems. In Zhejiang Province’s photovoltaic storage project, 15,000 of these relays manage bidirectional power flow between solar arrays and the grid, achieving 99.983% operational uptime since installation.
“It’s not just about switching currents,” says Li Wei, senior power engineer at State Grid Corporation. “The HC10AR’s patented AR (Anti-Rebound) contact system prevents micro-sparking – a game-changer for sensitive IoT control circuits.”
