Problemlösung & Einsatznutzen

Resolves power grid instability, operational energy dissipation, and equipment protection challenges.

Zielgruppe und Einsatzbereich

Critical telecom facilities, data centers, utility substations, and industrial continuous power plants.

Wesentliche Vorteile

  • Ultra-Wide AC Window: Maintains uninterrupted operation down to 85Vac in rural or unstable grid environments with linear derating.
  • Live Hot-Plug Reliability: Gold-plated blind-mate connectors ensure spark-free online insertion and extraction with zero downtime.
  • Full Circuit Self-Protection: Built-in AC over/undervoltage shutdown, DC overvoltage latching, thermal foldback, and short-circuit protection.
  • Low EMI Emissions: Certified to EN 55022 Class B standards, preventing high-frequency noise interference with co-located RF gear.
