APC Smart-UPS SRT Tower Isolation/Step-Down Transformer

The APC Smart-UPS SRT Tower Isolation/Step-Down Transformer is a strategic accessory designed to tailor the Smart-UPS to meet precise power delivery needs in data centers, server rooms, and critical IT environments. This 5kVA isolation and step-down transformer integrates seamlessly with the Smart-UPS SRT lineup to provide a clean, stabilized power path for sensitive equipment. By isolating the load from stray electrical noise, harmonics, and line disturbances, it helps extend equipment life, improve uptime, and protect valuable IT assets from power quality issues. With a versatile outlet configuration that includes a mix of NEMA types, this transformer supports a wide range of devices—from servers and network gear to telecom and storage systems—without forcing compromises on performance or space.

• Flexible outlet configuration to support diverse equipment: The unit features 8x 5-20R outlets, 2x L6-20R outlets, 1x L6-30R outlet, and 1x L14-30R outlet, enabling you to power a broad mix of devices from a single, centralized distribution point. This grouping makes it easier to consolidate critical loads and simplify cabling in tight IT spaces.
• 5 kVA capacity for scalable protection: With a 5 kVA rated transformer, this solution accommodates mid-to-large load profiles common in resilient IT environments. It provides ample headroom for standard servers, storage arrays, and network infrastructure while leaving room for future growth without needing a complete power redesign.
• Isolation and step-down for superior power quality: The isolation and step-down design decouples sensitive equipment from fluctuations and noise on the incoming utility line. This reduces voltage transients, electrical noise, and harmonics that can affect performance, reliability, and uptime of critical systems.
• Rugged, purpose-built tower form factor: Engineered to sit alongside the Smart-UPS SRT in a tower configuration, the transformer integrates into IT rooms, data centers, and equipment closets where space efficiency and airflow are paramount. The compact footprint keeps pathways clear while delivering robust protection.
• Seamless integration with APC monitoring and management: The transformer is designed to work in harmony with APC’s ecosystem, enabling centralized monitoring, easier asset management, and streamlined maintenance through existing Smart-UPS SRT workflows—helping you maintain consistent, highly available power to critical loads.

How to Install APC Smart-UPS SRT Tower Isolation/Step-Down Transformer

• Plan the installation in a clean, ventilated area with adequate clearance around the unit for airflow and cable management. Verify that the site matches your load requirements and that the UPS and transformer are compatible in voltage and phase configuration.
• Power down the Smart-UPS SRT and disconnect it from the main power source before beginning installation. Ensure all connected devices are safely powered down and that the work area is de-energized.
• Mount the transformer in a stable location adjacent to the UPS, maintaining proper spacing for cooling. Securely position the unit to minimize vibration and reduce the risk of accidental disconnections.
• Connect the transformer input using the appropriate cabling from the UPS output or designated distribution path, following the manufacturer’s wiring diagram. Ensure correct grounding and adherence to all electrical codes. Attach the transformer’s outlets to your critical devices, prioritizing essential loads for the isolated/step-down path.
• Power on the UPS and the transformer, then verify proper operation using the APC monitoring software or the UPS interface. Check individual outlets to confirm voltage levels are stable and within acceptable tolerances for each connected device. Conduct a brief load test to ensure all critical equipment remains protected under normal operating conditions.
