Sola S1K-S3K Online UPS Double Conversion Pure Sine Wave Power Supply

The Sola S1K–S3K Uninterruptible Power Supply (UPS), available through Rice Lake, is a high-performance online double-conversion UPS system designed to provide continuous, clean, and reliable power for critical electronic equipment. Engineered for industrial weighing systems, automation controls, computers, network infrastructure, laboratory equipment, data acquisition systems, and process control applications, the S1K–S3K Series protects sensitive electronics from power outages, voltage fluctuations, surges, brownouts, sags, and electrical noise. The online UPS design continuously conditions incoming power, ensuring connected equipment receives stable output power regardless of utility power quality. ([link removed by eBay])

Unlike standby or line-interactive UPS systems, the S1K–S3K Series utilizes true online double-conversion technology that converts incoming AC power to DC and then back to regulated AC power. This process completely isolates connected equipment from utility power disturbances while providing zero transfer time during power interruptions. The result is uninterrupted operation for mission-critical systems where downtime or data loss cannot be tolerated.

The S1K–S3K Series features pure sine wave output, making it ideal for sensitive electronics, weighing indicators, servers, communication equipment, industrial controllers, and laboratory instrumentation. Advanced digital signal processor (DSP) control technology continuously monitors and regulates power conditions to deliver exceptional voltage regulation and frequency stability. The UPS also provides comprehensive protection against spikes, surges, harmonics, and electrical interference that can damage equipment or disrupt operations.

A front-panel LCD display provides real-time system monitoring, including input voltage, output voltage, battery status, load levels, operating mode, and alarm conditions. The intuitive interface allows users to quickly assess system performance and battery health while simplifying UPS management. Audible alarms notify operators of power events, battery operation, overload conditions, and maintenance requirements.

The internal maintenance-free sealed lead-acid battery system provides dependable backup power during outages, allowing critical equipment to continue operating or shut down safely. Automatic battery charging and intelligent battery management help maximize battery life and maintain readiness for unexpected power failures. Optional external battery packs can be added to extend runtime for applications requiring longer backup durations.

Designed for flexibility, the S1K–S3K Series supports both tower and rackmount installations, making it suitable for industrial control rooms, network closets, server rooms, manufacturing facilities, laboratories, and weighing stations. Built-in communication ports support UPS monitoring and management through connected computer systems, helping facilities maintain visibility and control over critical power infrastructure.

Whether protecting a truck scale control system, industrial automation equipment, network server, laboratory instrument, or data collection workstation, the Sola S1K–S3K UPS delivers dependable online power protection and battery backup for mission-critical operations.
