Product Features
Technical Overview
This UPS employs double-conversion online topology, which continuously converts incoming AC power to DC and back to AC, ensuring output power is isolated from input anomalies. The system maintains a consistent 60 Hz output frequency regardless of input fluctuations, providing precise power conditioning for sensitive electronics.
Power distribution is handled through 12 receptacles: eight NEMA 5-20R outlets and four NEMA L6-30R outlets, accommodating a mix of standard and high-power equipment. A serial port enables monitoring and management capabilities, allowing integration with power management software for proactive maintenance and shutdown procedures.
This section brings together practical product details such as Plug/Connector Type, Receptacle Type, Receptacle Detail, Load Capacity (VA), so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.
A strong technical summary explains how the product's interfaces, hardware profile, and operating characteristics work together in real deployment. Buyers often need this context to confirm compatibility with existing devices, expected performance in daily use, and whether installation will be straightforward for IT staff or end users.
Key Product Advantages
The Powerware 9155 combines industrial-grade construction with Eaton's power management expertise, resulting in a UPS that prioritizes reliability and serviceability. Its tower design simplifies installation in standard equipment rooms without requiring specialized rack infrastructure.
High-Capacity Protection
With 15 kVA capacity, this UPS supports substantial equipment loads, making it ideal for server rooms, network closets, or industrial applications where multiple devices require uninterrupted power.
- 15 kVA load capacity
- Supports 110V and 220V input
- Wide output voltage range
Reliable Runtime Configuration
The system includes 32 lead-acid batteries configured to deliver 4.6 minutes of runtime at full load, providing critical window for safe shutdown or generator transition during extended outages.
- 32-battery array
- Lead-acid chemistry
- 4.6-minute full-load runtime
Deployment / Use Cases
This UPS is particularly effective in environments where power quality varies or where brief outages are common. The double-conversion technology ensures connected equipment receives clean sine wave output regardless of input conditions, protecting against the gradual degradation that can occur with inferior power conditioning.
For facilities with generator backup, the 9155 provides seamless bridging during generator startup, maintaining continuous operation through the transition. Its runtime allows sufficient time for generators to stabilize or for orderly shutdown procedures when extended backup isn't available.
Server Room Protection
Deploy in small to medium server environments where consistent power is essential for uptime. The 15 kVA capacity and multiple outlet types support mixed server, storage, and networking equipment.
Industrial Control Systems
Protect manufacturing or process control equipment from power anomalies that could disrupt operations. The wide input voltage range accommodates various industrial power configurations.
Physical Profile
The tower form factor measures 32.20" in height, 12" in width, and 34" in depth (817.88 mm × 304.80 mm × 863.60 mm), providing a substantial footprint for the 15 kVA capacity while maintaining manageable dimensions for standard equipment room layouts. The vertical design optimizes floor space utilization compared to rack-mounted alternatives, making it suitable for environments without dedicated rack infrastructure.
