APC Smart-UPS SURT1000XLI-CH 1000VA/900W Online Double Conversion UPS with Built-in Battery

The APC Smart-UPS SURT1000XLI-CH is a high-performance 1kVA/900W Online Double Conversion Uninterruptible Power Supply. Engineered to deliver ultimate power protection, it features a highly flexible Rack/Tower convertible design (2U). This UPS continuously regulates voltage and frequency, providing a calibrated pure sine wave output with zero transfer time—ensuring no interruption from mains to battery power. Equipped with a built-in maintenance-free VRLA battery, an Emergency Power Off (EPO) function, and a high power factor of 0.9, it is the ideal choice for safeguarding highly sensitive communication equipment, servers, and industrial controls.

Key Functions and Features

High Availability & Pure Power

Zero Transfer Time: True online double conversion topology guarantees zero milliseconds of interruption when switching to battery power, ensuring seamless operation for critical loads.

Wide Input Voltage Range: Supports 160275 VAC at full load (and 100275 VAC with derating), effectively reducing unnecessary battery usage and extending battery lifespan.

Generator Compatible: Provides a calibrated pure sine wave output and actively corrects frequency variations, making it perfectly compatible with backup power generators.

Smart Battery Management

Hot-Swappable Batteries: The load can work continuously without interruption while the user safely replaces the internal batteries.

Fast Charging System: The robust 1.8A charging current recovers power supply capabilities quickly, charging the battery to 90% in less than 3 hours.

Microprocessor Control: Uses advanced test diagnostic systems to control charging and maximize battery life. It also supports a “Cold Start” to activate the system even without mains power.

Flexible Design & Intelligent Management

Rack/Tower Convertible: Fits into a standard 19-inch rack occupying only 2U of space (using the optional SURTRK-CH rail kit), or stands vertically as a tower.

Multifunctional LCD: An intuitive control panel provides real-time status updates.

Advanced Networking: Includes a SmartSlot for optional Web/SNMP management cards and supports PowerChute network shutdown software.

Frequently Asked Questions (FAQ)

Q1: What does “Online Double Conversion” mean for the SURT1000XLI-CH?

A: It means the UPS continuously converts AC power to DC and then back to highly regulated AC power. This provides a zero transfer time to the battery during a blackout, ensuring your critical equipment experiences absolutely no power interruption.

Q2: Is this a Rack-mounted or Tower UPS?

A: The SURT1000XLI-CH features a Rack/Tower convertible design. You can stand it vertically as a tower or mount it in a standard 19-inch IT rack where it occupies only 2U of space (requires the SURTRK-CH guide rail).

Q3: Can I replace the battery without turning off the connected equipment?

A: Yes! This UPS features hot-swappable batteries. The load can work continuously while the user safely replaces the APCRBC48BP-CH internal battery pack.

Q4: How long will the battery last during an outage?

A: With the built-in VRLA battery, it provides an impressive typical runtime of 28.3 minutes at half load and 10.8 minutes at full load (900W).

Q5: Does this model support Emergency Power Off (EPO)?

A: Yes, it is equipped with an EPO connector, allowing the UPS to be immediately shut down from a central fire alarm or emergency switch system, meeting strict data center safety regulations.
