Description
The CyberPower OL5KSTF is a high-capacity rack/tower step-down isolation transformer designed to convert 200–240V input power from utility sources, UPS systems, or generators into a stable 120V output for critical IT and network equipment.
With a powerful 5,000 VA / 5,000 W capacity, this transformer is ideal for enterprise server rooms, virtualization infrastructures, storage systems, and core networking environments requiring reliable voltage conversion.
The OL5KSTF includes twelve NEMA 5-20R outlets, overload circuit breaker protection, and built-in over-temperature safeguards to ensure dependable operation under demanding conditions. Its 2U rackmount form factor makes deployment seamless in professional data center setups.
Backed by a 3-year limited warranty, the OL5KSTF delivers long-term power conversion confidence for mission-critical applications.
