The APC Easy UPS 3S 15 kVA 400 V 3:3 UPS with internal batteries (model E3SUPS15KHB1) is a high-efficiency, three-phase uninterruptible power supply (UPS) designed by Schneider Electric to ensure business continuity in small to medium-sized data centers, server rooms, and electrical environments. With a 9-minute runtime, robust electrical design, and user-friendly features, this UPS is tailored for businesses seeking reliable power protection. In this blog, we’ll explore its key features, performance, applications, and overall value to help you decide if it’s the right solution for your infrastructure.
Key Features
1. High-Efficiency Power Protection
The E3SUPS15KHB1 delivers a 15 kVA / 15 kW power capacity in a 3:3 phase configuration, ensuring balanced power distribution for critical equipment. Its double-conversion online topology provides consistent, clean power by converting incoming AC to DC and back to AC, protecting against power surges, sags, and outages. With an efficiency rating of up to 94% in online mode and 98% in ECO mode, it minimizes energy waste, reducing operational costs.
2. 9-Minute Runtime with Internal Batteries
Equipped with internal 7Ah modular batteries, the UPS provides a 9-minute runtime at full load, sufficient to bridge short power outages or allow safe shutdown of connected equipment. The runtime can be extended by adding up to three external battery strings, offering scalability for businesses with growing power needs. For detailed runtime charts, refer to Schneider Electric’s official documentation.
3. Compact and Easy-to-Install Design
The Easy UPS 3S is designed for simplicity, with a compact footprint that integrates seamlessly into standard 19-inch racks or electrical rooms. Weighing approximately 60 kg (132 lbs) without batteries, it’s relatively lightweight for a three-phase UPS. The unit includes input, output, and bypass breakers, as well as an Emergency Power Off (EPO) switch, simplifying installation. Its front-access servicing minimizes downtime during maintenance, and the included dust filter and conformance-coated boards ensure reliability in harsh environments.
4. User-Friendly Features
The UPS features an intuitive LCD interface for real-time monitoring of power status, battery health, and system diagnostics. The Easy Loop Test verifies performance without a load bank, ensuring the UPS is ready before connecting critical equipment. Additionally, the ECO Mode bypasses unused electrical components during stable power conditions, boosting efficiency without compromising protection.
5. Robust Build and Global Certifications
Built by Schneider Electric, the E3SUPS15KHB1 adheres to stringent safety and performance standards, including CE, IEC 62040-1, and IEC 62040-2. It operates reliably in temperatures from 0°C to 40°C (32°F to 104°F) and supports altitudes up to 3,000 meters. The UPS is manufactured in China and comes with a 1-year warranty, with optional extended service plans available.
6. Eco-Friendly Design
The Easy UPS 3S aligns with Schneider Electric’s Green Premium label, ensuring compliance with environmental regulations like RoHS and REACH. It features low-CO2 components and a lifecycle carbon footprint of approximately 350 kg CO2 eq. Schneider’s take-back program in select regions supports responsible recycling, making it an environmentally conscious choice.
7. Comprehensive Accessories
The package includes:
- Dust filter: Protects internal components in dusty environments.
- Installation guide: Simplifies setup with clear instructions.
- Optional accessories: Battery breaker kit (E3SOPT008) and cord retention brackets for secure connections.
Performance
The E3SUPS15KHB1 delivers reliable power with the following specifications:
- Input Voltage: 380–415 V (400 V nominal), 3-phase.
- Output Voltage: 380–415 V, 3-phase, with <3% voltage distortion and 50/60 Hz frequency (sync to mains).
- Power Capacity: 15 kW / 15 kVA, suitable for medium-density IT loads.
- Efficiency: Up to 94% in double-conversion mode and 98% in ECO mode.
- Runtime: 9 minutes at full load with internal batteries, scalable with external battery packs.
Real-world tests show stable performance for servers, networking equipment, and storage systems, with seamless transitions during power disruptions. The double-conversion topology ensures minimal output voltage distortion, making it ideal for sensitive electronics.
Reliability and Build Quality
Schneider Electric’s reputation for quality is evident in the E3SUPS15KHB1. The UPS’s robust electrical design and conformance-coated boards protect against dust, humidity, and other environmental factors. The 1-year warranty provides baseline assurance, and Schneider’s 24/7 support (via phone, email, or on-site) ensures quick resolution of issues. However, users requiring longer runtimes may need to invest in additional battery packs, as the 9-minute internal battery runtime is relatively short for high-demand environments.
Applications
The Easy UPS 3S 15 kVA is ideal for:
- Small to Medium Data Centers: Protects servers, storage, and networking equipment.
- Enterprise IT: Ensures uptime for critical applications in offices or branch locations.
- Industrial Environments: Supports equipment in harsh conditions with dust filters and coated boards.
- Healthcare and Retail: Powers sensitive systems requiring uninterrupted operation.
For users needing advanced features like remote monitoring or outlet-level control, Schneider’s higher-end models, such as the Smart-UPS VT or Galaxy series, may be more suitable, though they come at a higher cost.
