UPS APC SRTL5KRM2UI-HW Double-conversion (Online) 5 kVA / 5000 W Rackmount 2U Lithium‑Ion 180 V

APC SRTL5KRM2UI-HW is a double-conversion (online) UPS delivering 5 kVA / 5000 W of continuous output power in a 2U rack/tower form factor. It uses lithium‑ion battery technology with a nominal battery voltage of 180 V and provides ultra-high power density and scalable extended runtime options. The unit is supplied with rail kit and accessories including a 2P–3P connector, earth terminal block, front cover, rail extension, stabilization feet, temperature sensor and USB cable.

Advantages

The Smart-UPS Ultra on-line design ensures consistent, regulated power with zero transfer time to battery, protecting sensitive equipment from wide input disturbances. Lithium‑ion batteries offer longer lifecycle and higher energy density compared with lead‑acid alternatives, reducing total cost of ownership and allowing more compact rack installation. Rack/tower flexibility and included rail kit simplify deployment in data centre or edge environments.

Suitable for

• Data centre racks and server rooms requiring continuous, high-quality power
• Edge computing sites and telecom closets with limited rack space
• Critical infrastructure where extended runtime and predictable battery behaviour are needed

When it may not be suitable

This UPS is designed for 230 V environments and hardwired three‑wire output installations; it may not be appropriate for locations that require a different nominal output voltage or plug‑and‑play receptacle outputs. For very small office desktops or single non‑critical devices, the physical size (2U) and power capacity may be excessive compared with compact, lower‑capacity models.

How to use

Install the UPS in a standard 19-inch rack using the supplied rail kit or place it on a flat surface using the stabilization feet in tower mode. Connect the mains input to a compatible 230 V supply and wire the hardwired three‑wire output to the protected load according to local electrical codes. Use the network card for remote monitoring and management, and connect the temperature sensor where indicated to enable battery thermal management. Follow the user manual for initial battery charging, configuration of runtime extensions, and regular maintenance checks.

What to consider before purchase

• Confirm site mains voltage is 230 V and that hardwired three‑wire output is acceptable
• Verify rack space (requires 2U) and physical depth (701 mm) fit cabinet or deployment location
• Assess required runtime and whether additional external runtime packs or scalable options are needed
• Plan for weight (29.2 kg) when mounting and for appropriate cooling and ventilation

Usage recommendations

For reliable operation, register and monitor the UPS via the network card, perform periodic battery self‑tests, and maintain ambient temperature within vendor‑recommended ranges to maximise lithium‑ion battery life and ensure predictable extended runtime.
