Airflow Management Awareness Month

Our 6th annual Airflow Management Awareness Month webinar series has concluded. Watch the webinars on-demand now!

Watch On-Demand
  • Online Double-Conversion Topology: Continuously conditions incoming AC power with zero millisecond transfer time to battery during power outages.
  • Highly Scalable External Battery Pack Architecture: Supports adding up to seven matching external battery packs (BP36, BP48, or BP72) with an adjustable charger (up to 8 A) that recharges systems to 95% in under 3 hours.
  • Near-Unity Output Power Factor (2U Models): Delivers higher active power output (e.g., up to 1450 W on a 1500 VA unit and 2880 W on a 3000 VA unit).
  • Shallow-Depth 2U/1U Convertible Form Factor: Compact physical depth (starting at 15.1 inches) with included brackets for rack or tower installation, plus wall-mount options.
  • Serviceability & Auto-Restart Capabilities: Supports an optional maintenance bypass module (XBDM) and features automatic restart when utility power returns after a full battery discharge.
  • Uninterrupted, High-Quality Power Protection: Isolates critical network, AV, and IT equipment from sags, spikes, noise, and frequency variations, preventing hardware damage and data loss.
  • Customizable & Extended Back-up Runtimes: Allows organizations to engineer specific runtime goals per site—scaling from a few minutes of ride-through up to two hours—without overpaying for larger, fixed-runtime UPS units.
  • Maximum Usable Capacity Per Rack: Provides more real wattage per VA than competing units, allowing you to power higher-density equipment loads without stepping up to a larger frame size.
  • Fits Tight Equipment Racks & Closets: The shallow chassis depth fits easily into short-depth racks and crowded IT spaces while leaving room for cable management.
  • Minimized Downtime & Reduced Site Visits: The optional maintenance bypass lets technicians swap or service the UPS without dropping connected loads, while auto-restart automatically recovers systems after prolonged outages without requiring an on-site technician.
