About Us

PowerSentinel — 30+ Years of Critical Power Engineering

Founded in Zurich in 1992, PowerSentinel has grown from a regional UPS specialist to a global manufacturer of industrial power protection systems, serving critical infrastructure across 94 countries.

Who We Are

Built on Three Decades of Field-Proven Expertise

PowerSentinel was established with a single engineering conviction: that every industrial facility, healthcare system, and critical infrastructure project deserves power protection designed to the same standard as the critical systems it protects.

Today, our 2,800+ employees across 6 manufacturing sites and 18 regional offices deliver complete critical power solutions — from single rack UPS units to megawatt-scale modular power centers — to data center operators, pharmaceutical manufacturers, energy utilities, and rail operators worldwide.

Unlike conglomerates where power protection is one product line among hundreds, critical power is our sole focus. This concentration of expertise translates into deeper application knowledge, faster documentation response, and engineering accountability that generalist suppliers cannot match.

Engineering a Lower-Carbon Critical Power Future

ISO 14001 Manufacturing

Our six manufacturing sites operate under ISO 14001 certified environmental management systems, with independently audited CO₂ reduction targets — 38% reduction per unit achieved over five years.

High-Efficiency Products

Every percentage point of UPS efficiency improvement reduces customer facility power consumption directly. Our 97.5% peak efficiency products contribute measurably to customer Scope 2 carbon reduction goals.

End-of-Life Battery Management

Our battery take-back program ensures compliant WEEE disposal for all battery chemistries — VRLA, Li-ion, and NiCd — through certified recycling partners in 40+ countries.
