UPS Total Cost of Ownership

Every point of inefficiency leaves as heat and is paid for twice - at the UPS, then at the cooling plant, scaled by site PUE. Numeric three-phase systems deliver up to 96% in double conversion, above 98% in ECO mode.

At 0.8 output power factor, a 100 kVA system delivers 80 kW, and the specification has to be oversized by a quarter. Numeric three-phase systems deliver unity output power factor.

Distortion drawn back into the supply adds heat, raises cooling demand, and usually needs external filtering that sits outside the quotation. Numeric's IGBT rectifier with integrated PFC holds input distortion below 3% THDi at above 0.99 input power factor - no added filtering, no transformer oversizing.

Chemistry selected at procurement sets both acquisition cost and replacement profile. VRLA and lithium-ion diverge over a ten-year horizon. Numeric supports both, so the decision follows the site's temperature envelope and reinvestment cycle rather than the platform's limits.

N, N+1 and 2N commit different capital, and over-provisioning on day one sits idle for years. Numeric's modular architecture adds capacity in power modules as load grows, reaches N+1 by adding a module rather than duplicating the system, and allows hot-swap in place.

MTBF and MTTR are set by architecture, not by the service report. A monolithic UPS concentrates risk in one controller, one bypass, one repair event. Numeric distributes intelligence across power modules and decentralises the bypass, so a failed module is extracted and replaced while the rest carry the load in double conversion.
