Vertiv EXSV-40KTN 40kVA UPS Frame with Internal VRLA Battery and Top Fan Venting

Overview

The Vertiv EXSV-40KTN is a 40kVA uninterruptible power supply designed for mission-critical commercial and industrial deployments where a self-contained, internally-batteried UPS frame is required. Built around a 208V input topology and housing a 50Ah internal VRLA battery bank, it ships as a complete, ready-to-commission unit — no external battery cabinet required for baseline runtime. The top fan venting configuration makes it particularly well-suited for hot-aisle/cold-aisle raised-floor environments and enclosed equipment rooms where airflow direction matters for thermal management. If you are spec'ing power protection for a mid-size network video recorder room, a comms closet, or a surveillance head-end with a dense PoE switch stack, the 40kVA frame fits the load band where a smaller UPS leaves headroom risk and a larger frame over-specs the install.

Key Features

• 40kVA Power Rating: At 40kVA, this frame handles substantial IT and security infrastructure loads — enough to cover a fully populated NVR rack, PoE switch infrastructure, and ancillary network gear in a single UPS footprint. Sizing at this tier avoids the load-sharing complexity of paralleled smaller units.
• 50Ah Internal VRLA Battery: The sealed, valve-regulated lead-acid battery is housed internally, eliminating the need for a separate battery enclosure in space-constrained rooms. VRLA chemistry requires no watering, minimal maintenance checks, and is safe for indoor installation without special ventilation permits.
• 208V Input Voltage: Native 208V single-phase or three-phase input aligns with standard North American commercial building power distribution, letting you tie directly to a 208V PDU or panel without step-up transformer costs. Verify your panel breaker sizing against the full 40kVA draw before commissioning.
• Top Fan Venting: Exhaust directed upward integrates cleanly with hot-aisle containment systems and overhead cable trays. In a sealed rack row, top venting prevents recirculation of hot exhaust back into adjacent equipment intakes — a meaningful thermal discipline point that bottom-venting units cannot match in tight installations.
• Self-Contained Frame Design: The EXSV-40KTN is engineered as an integrated unit — battery, electronics, and venting in one frame — which simplifies site preparation, reduces installation labor, and shortens commissioning time compared to modular battery-separate configurations.

Integration and Compatibility

The EXSV-40KTN fits naturally into commercial UPS deployments alongside Vertiv's broader power management ecosystem. At 208V input, it is compatible with standard North American commercial panel configurations. For deployments pairing this unit with high-draw PoE network switches or dense compute loads, confirm total connected load does not exceed the 40kVA nameplate — derate to 80% (32kW at unity PF) for continuous operation per standard power engineering practice. Consult a UPS selection guide if you are sizing between this frame and adjacent capacity tiers in the Vertiv EXS line. For extended runtime beyond what the internal 50Ah bank provides, confirm with the manufacturer whether external battery modules are supported on this specific frame variant before procurement.

Frequently Asked Questions

Q: What is the input voltage requirement for the EXSV-40KTN?

A: The EXSV-40KTN operates on 208V input, standard for North American commercial power distribution panels.

Q: Does the EXSV-40KTN include a battery, or is a separate battery cabinet required?

A: It includes an internal 50Ah VRLA battery, so no external battery cabinet is required for baseline operation.

Q: Why does the top fan venting matter for my installation?

A: Top fan venting directs exhaust upward, which is essential for hot-aisle containment and prevents hot air recirculation in sealed rack rows — a thermal management advantage over bottom or rear-venting units.

Q: What is the 40kVA rating in practical terms for a security or IT room?

A: 40kVA is sufficient to protect a fully populated NVR rack, PoE switching infrastructure, and network equipment in a mid-size surveillance or IT head-end. Derate to 80% (roughly 32kW at unity power factor) for continuous load design.

Q: Is the VRLA battery maintenance-intensive?

A: No. VRLA (valve-regulated lead-acid) batteries are sealed and require no watering or electrolyte checks — only periodic capacity testing per manufacturer maintenance schedules.

Marty Allison

The EXSV-40KTN is the frame I reach for when a project needs a fully self-contained 40kVA UPS at 208V without the footprint or cost of a separate battery enclosure. That 50Ah internal VRLA bank means you're walking into a comm room with one box, not two — and on a mid-size security or IT deployment, that matters for both space planning and installation scheduling.

Technical Highlights:

• 40kVA Capacity: Enough headroom for a fully loaded NVR rack plus PoE switching — design to 80% continuous (32kW at unity PF) to stay within safe operating margins.
• Internal 50Ah VRLA Battery: Sealed chemistry, no venting permits, no external cabinet — reduces BOM complexity and simplifies the one-line drawing on the electrical side.
• Top Fan Venting: In hot-aisle/cold-aisle raised-floor rooms, upward exhaust is the correct configuration — it cooperates with overhead return air paths instead of fighting them.

Deployment Considerations:

• Confirm panel breaker sizing before commissioning — at full 40kVA on a 208V feed, input current is substantial; an undersized breaker is the most common commissioning delay on this class of UPS.
• The internal 50Ah bank provides baseline runtime only — if your runtime spec exceeds what 50Ah delivers at your connected load, verify whether external battery modules are supported on this frame variant before finalizing the procurement.

The EXSV-40KTN is a strong fit for mid-size surveillance head-end rooms and comms closets on commercial campuses where the electricals are already at 208V and the project cannot accommodate a multi-cabinet UPS footprint.
