Q: Does the Liebert EXS 60kVA support parallel clustering, and how does it manage battery bus configuration and load sharing?

The Liebert EXS 60kVA supports direct paralleling of up to 4 units for N+X redundancy or capacity scaling up to 240kVA/240kW using a redundant ring parallel bus, achieving load sharing imbalance under 3%. The DC bus offers flexible battery cell configuration ranging from 30 to 44 blocks of 12V VRLA (default 36/40 blocks) and supports modern Lithium-ion BMS integration. It features an integrated Battery Circuit Breaker (BCB), programmable temperature compensation charging, and automated battery impedance/self-test routines to mitigate the risk of single-cell degradation cascading into DC bus collapse.

Q: What reliability designs enable the EXS 60kVA to withstand harsh industrial, high-temperature, and remote edge telecom environments?

The EXS 60kVA features a compact floor-standing form factor (footprint ~0.35–0.6 m²) with full front-access serviceability. Critical internal PCBA assemblies are treated with industrial-grade conformal coating against dust, humidity, and chemical contaminants. It delivers continuous full-load operation from 0°C to 40°C (with derated output operation sustained up to 50°C). Thermally, it employs an isolated airflow channel isolating sensitive DSP controls from the high-temperature IGBT power stage. Integrated with IEC/EN 62040-2 Category C3 EMC filters and robust surge protection, it resists harsh grid transients and electromagnetic interference.

Question 1

What are the core electrical specifications and power efficiency metrics of the Vertiv Liebert EXS 60kVA (SKU: VERTIV-UPS-EXS-60KVA)?

Accepted Answer

The Vertiv Liebert EXS 60kVA leverages an advanced three-level online double-conversion topology, delivering 60kVA / 60kW with a true Unity Power Factor (PF 1.0, kVA=kW without derating). It supports an ultra-wide three-phase input window of 228 to 477 VAC with input PF >0.99 and THDi <3%. In double-conversion mode (VFI), conversion efficiency reaches up to 96.2% (exceeding 99% in ECO mode). Output voltage is selectable among 380/400/415 VAC. Inverter overload tolerance supports 110% for 60 mins, 125% for 10 mins, and 150% for 1 min, ensuring continuous mission-critical protection against transient inrush currents in enterprise server rooms and edge telecom hubs.
