Frequently Asked Questions
Concise, citable answers — written so AI search engines can quote them directly.
What is the difference between modular and traditional UPS?
A modular UPS grows by adding hot-swappable power modules (N+1 redundancy) so you pay for capacity as load grows and replace a module without downtime. Traditional (monolithic) UPS is fixed-size and single-point. Modular wins for data centres and sites with evolving load.
How do I size a UPS?
Size by real load (watts, not VA) plus desired runtime. Rule: UPS capacity ≥ 1.25 × continuous load; battery bank sized for minutes-to-hours of runtime at that load. We do a load audit and recommend capacity + battery to meet your runtime target.
How long do UPS batteries last?
VRLA batteries typically last 3–5 years; Lithium-ion 8–10 years. Life depends on temperature (every 8°C over 25°C halves life) and discharge depth. We spec temperature-compensated charging and remote battery health monitoring.
Can UPS be used in harsh industrial environments?
Yes — our industrial UPS has wide input-voltage tolerance, dust/heat/humidity resistant enclosures and conformal-coated boards for factories, pumps and process control where grid quality is poor.
