Offering a 15-minute runtime at full load, this three-phase UPS combines ease of use, scalability, and cost-effectiveness. In this blog, we’ll explore its key features, performance, applications, and overall value to help you determine if it’s the right power solution for your needs.
Key Features
1. Powerful and Efficient Power Protection
The E3SUPS20KHB1 provides a 20 kVA / 20 kW power capacity in a 3:3 phase configuration, ensuring balanced power distribution for demanding IT and industrial equipment. Its double-conversion online topology delivers clean, stable power by converting incoming AC to DC and back to AC, safeguarding against power disruptions like surges, sags, and outages. With an efficiency of up to 94% in online mode and 98% in ECO mode, it reduces energy costs while maintaining high performance.
2. 15-Minute Runtime with Internal Batteries
Equipped with internal 7Ah modular batteries, the UPS offers a 15-minute runtime at full load, providing ample time to handle short power outages or initiate safe shutdowns of connected systems. For extended runtime, the system supports up to three external battery strings, offering scalability for businesses with evolving power demands. Runtime charts are available on Schneider Electric’s website for precise planning.
3. Compact and Installation-Friendly Design
The Easy UPS 3S 20 kVA is designed for space-constrained environments, with a compact footprint suitable for standard 19-inch racks or electrical rooms. Weighing approximately 65 kg (143 lbs) without batteries, it’s manageable for a three-phase UPS. The unit includes input, output, and bypass breakers, an Emergency Power Off (EPO) switch, and front-access servicing for easy maintenance. A dust filter and conformance-coated boards enhance durability in challenging environments like dusty or humid facilities.
4. Intuitive User Interface
The UPS features a graphical LCD display for real-time monitoring of power status, battery health, load levels, and system diagnostics. The Easy Loop Test allows technicians to verify UPS performance without a load bank, streamlining setup and maintenance. The ECO Mode optimizes efficiency by bypassing unused components during stable power conditions, ensuring cost savings without sacrificing reliability.
5. Global Safety and Compliance
The E3SUPS20KHB1 meets rigorous international standards, including CE, IEC 62040-1, and IEC 62040-2, ensuring safe and reliable operation worldwide. It functions effectively in temperatures from 0°C to 40°C (32°F to 104°F) and at altitudes up to 3,000 meters. Manufactured in China, it comes with a 1-year warranty, with optional extended service plans available through Schneider Electric.
6. Eco-Conscious Design
Part of Schneider Electric’s Green Premium portfolio, the E3SUPS20KHB1 complies with environmental regulations like RoHS and REACH. Its packaging uses recycled materials, and the unit has a lifecycle carbon footprint of approximately 400 kg CO2 eq.. Schneider’s take-back program in select regions supports responsible recycling, aligning with sustainability goals.
7. Comprehensive Accessories
The package includes:
- Dust filter: Protects internal components in harsh environments.
- Installation guide: Provides clear instructions for quick setup.
- Optional accessories: Battery breaker kit (E3SOPT008) and cord retention brackets for secure connections.
Performance
The E3SUPS20KHB1 delivers robust performance 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: 20 kW / 20 kVA, ideal for medium-density IT and industrial loads.
- Efficiency: Up to 94% in double-conversion mode and 98% in ECO mode.
- Runtime: 15 minutes at full load with internal batteries, extendable with external battery packs.
The double-conversion topology ensures minimal output voltage distortion, making it suitable for sensitive equipment like servers, networking gear, and medical systems. Real-world tests demonstrate seamless transitions during power disruptions, ensuring uninterrupted operation.
Reliability and Build Quality
Schneider Electric’s expertise shines in the E3SUPS20KHB1’s durable construction. The conformance-coated boards and dust filter enhance reliability in challenging conditions, while the robust electrical design ensures consistent power delivery. The 1-year warranty provides standard coverage, and Schneider’s 24/7 support (via phone, email, or on-site) ensures prompt issue resolution. However, the 15-minute runtime may be limiting for high-demand environments, requiring additional battery packs for extended outages.
Applications
The Easy UPS 3S 20 kVA is well-suited for:
- Small to Medium Data Centers: Powers servers, storage systems, and networking equipment.
- Enterprise IT: Ensures uptime for critical applications in offices or branch locations.
- Industrial Settings: Supports equipment in dusty or humid environments with protective features.
