supports the continuous availability of your most important loads through all power conditions, providing a
compact backup power platform that’s easy to manage and inexpensive to operate. Sophisticated voltage
and frequency independent (VFI) operation and advanced IGBT rectifier technology with DSP control
deliver reliable output power quality. Providing up to 40kVA of clean, continuous power, this 3-phase UPS
system is perfect for critical applications in IT, communications, corporate, commercial, retail, financial,
security, transportation, emergency and edge infrastructure environments.
Best-in-Class Footprint for Easy Integration into Your Network ApplicationThis on-line doubleconversion UPS system has a very small footprint of just 0.24 square meters. It requires less valuable
space in your facility, and you can install the UPS system in spaces that would previously have required
expensive retrofitting.
Efficient Operation and Design Reduces Cost of OwnershipThis UPS benefits from highly efficient
transformer-free double-conversion technology that delivers operating cost savings. It achieves 94%
efficiency in double-conversion mode and up to 98% in ECO mode, reducing your power and cooling
costs. A low THDi (<3%) improves generator compatibility. A low THDv (2%) and active power factor
correction improve output performance. The hardware and firmware platform design reduces the number
of unique boards, improving mean time to repair (MTTR) and resulting in reduced downtime. Built-in static
and maintenance bypass transfer UPS load to utility power during faults, overloads and maintenance,
which also avoids costly system downtime.
Supplies Reliable Battery Backup with Expandable Runtime OptionsInternal 10Ah batteries provide
15 minutes of support at half load and five minutes at full load with zero transfer time. Adding external
battery cabinets, such as BP480V10 (sold separately), provides extended runtime. The S3M40KX
automatically restarts after a lengthy power outage.
Intuitive LCD Interface Delivers Important Performance Information at a GlanceThe interactive frontpanel LCD interface displays critical operating conditions and diagnostic data, including operating mode,
input/output voltage, load, battery voltage, backup runtime and fault conditions. Four LEDs provide
information about line, bypass, battery and fault status.
Network Management Card Offers Remote Monitoring and ControlThe optional WEBCARDLX (sold
separately) with the latest version of PowerAlert Device Manager firmware (PADM20) provides enhanced
remote management capabilities, including customizable dashboard graphs to fit user preferences. The
PADM20 upgrade and Tripp Lite’s PowerAlert Element Manager (PAEM) software form a powerful tool for
