Overview

The APC SRT6KRMXLT delivers high-density, double-conversion on-line protection with a full 6kVA / 6kW capacity in a compact 4U rackmount footprint. Engineered for mission-critical IT, it outputs 208V (with 240V option) and includes a pre-installed Network Management Card 3 for remote visibility and control.

Key Features & Benefits

  • 6kVA / 6kW Capacity – Powers demanding servers, storage, and network hardware with headroom.
  • Double Conversion Online – Clean, conditioned sine wave independent of utility variations.
  • 208V Output with 240V Option – Suits North American rack power architectures.
  • Rich Outlet Mix – 2x L6-20R and 3x L6-30R plus hard-wire terminal for flexible distribution.
  • Network Management Card 3 – Built-in SNMP and environmental monitoring for remote management.
  • Scalable Runtime – Supports external battery packs; typical recharge time is 1.5 hours.

Technical Deep Dive

Double-conversion architecture continuously converts incoming AC to DC and then back to AC, ensuring the inverter always feeds the load. This isolates equipment from sags, surges, frequency drift, and harmonic distortion (<2%), delivering a stable sine wave for sensitive systems.

The UPS employs a 192V lead-acid battery system designed for high power density. Hot-swappable battery modules and a typical 1.5-hour recharge help restore readiness quickly after discharge while minimizing maintenance windows.

With a pre-installed Network Management Card 3 and a SmartSlot, administrators gain SNMP access, alarms prioritized by severity, and environmental sensor support—enabling proactive monitoring across distributed racks and sites.

Ideal Applications

  • Enterprise server and storage racks requiring 208V
  • Network closets and campus distribution with high-density loads
  • Industrial, healthcare, and finance IT needing continuous conditioned power
  • Edge and branch sites that require extendable runtime

Frequently Asked Questions (FAQs)

Q1: How is the SRT6KRMXLT installed?
A: It mounts as a 4U rack unit and ships with rails, brackets, support hardware, a temperature probe, and a USB cable for straightforward integration.

Q2: What performance and runtime should I expect?
A: The UPS supplies 6kVA / 6kW at 208V with sine wave output. Backup time varies by load and configuration; runtime can be extended using external battery packs. Actual results depend on load level, battery condition, and environment.

Q3: How is it managed?
A: A pre-installed Network Management Card 3 provides SNMP monitoring and environmental inputs. Audible/visible alarms are prioritized by severity, and a SmartSlot allows further expansion.
