This feature is particularly beneficial for businesses aiming to lower operational expenses while ensuring reliable power delivery.
2. 15-Minute Internal Battery Runtime
With two internal 7Ah modular battery strings (expandable to three), the UPS provides 15 minutes of runtime at full load, allowing sufficient time to switch to backup generators or safely shut down equipment during power outages. Detailed runtime charts are available in the product documentation for precise planning.
3. Wide Input Voltage Window
The UPS supports a wide input voltage range (304–477 V), preserving battery life by minimizing battery usage during minor power fluctuations. This feature ensures batteries are reserved for critical power outages, extending their lifespan and reliability.
4. Parallel Capability
Multiple E3SUPS20KHB1 units can be connected in parallel to increase power capacity or provide redundancy, making it scalable for growing businesses or mission-critical applications.
5. Remote Monitoring with Optional SNMP Card
An optional SNMP card enables remote monitoring and management through the UPS web interface or Schneider Electric’s EcoStruxure IT software suites (cloud-based and on-premise). This allows IT administrators to monitor UPS status, receive alerts, and perform maintenance from anywhere, enhancing operational efficiency.
6. Easy Installation and Maintenance
The UPS features a compact, lightweight design with front-access servicing, simplifying installation and maintenance while minimizing space requirements. Integrated input, output, and bypass breakers, along with an Emergency Power Off (EPO) switch, streamline deployment. The Easy Loop Test verifies performance without a load bank, ensuring reliability before connecting critical equipment.
7. Robust Design for Harsh Environments
The E3SUPS20KHB1 includes a dust filter and conformance-coated boards, making it suitable for challenging environments such as industrial settings or areas with high dust levels. Its IP20 protection class ensures durability in data centers and electrical rooms.
8. Intuitive User Interface
A multi-function LCD console provides real-time status updates, diagnostics, and configuration options, making the UPS user-friendly for operators of varying expertise levels.
Benefits of the E3SUPS20KHB1
