🌡️ Keep mission-critical infrastructure cool, quiet, and operational around the clock with the PRISM 4xFAN Controller. Engineered for telecom base stations, industrial control cabinets, and edge computing sites, this unit delivers high-precision, telecom-grade thermal management.
⚙️ Engineering-Grade Features:
🔹 Staged Cooling & Individual Logic: Independent control of up to 4 DC fans with configurable RPM profiles. Intelligent staged activation reduces mechanical wear, minimizes noise, and significantly extends MTBF.
🔹 Dual-Zone Temperature Monitoring: Equipped with dual digital probes to monitor both internal heat dissipation and external ambient solar loading for holistic climate control.
🔹 Advanced RS232 Connectivity: Provides a dedicated interface for real-time performance monitoring and custom thermal profile programming.
🔹 Critical Power Protection: External emergency shutdown integrates seamlessly with power management systems (LVD) to prevent fans from draining battery banks during critical power failures.
🔹 Integrated System Override: Features two dry-contact hardwire inputs and RS232 logic, allowing for third-party SCADA or PLC control during maintenance.
🔄 Universal Fan Compatibility:
Achieve total hardware flexibility. The 4xFAN Controller provides full support across all standard DC fan configurations:
✔️ 2-Wire (Voltage Controlled): Simple, robust speed control via supply voltage variation.
✔️ 3-Wire (PWM Signal): Voltage-speed control paired with real-time tachometer feedback for immediate fault detection.
✔️ 4-Wire (Full PWM Control): Dedicated PWM control signal plus tachometer for highly precise speed regulation that remains independent of supply voltage.
Available in industrial-grade solid black enclosures for harsh environments. Ensure absolute thermal stability without the need for constant on-site intervention.
