Description

The SOLAHD S4K5U6K5W0BATC is a high-performance 4 kVA (4000 VA / 3600 W) true online uninterruptible power supply (UPS) engineered specifically for demanding industrial automation and control environments. As part of SOLAHD’s ruggedized UPS portfolio, the SOLAHD S4K5U6K5W0BATC employs double-conversion topology to deliver clean, stable, pure sine wave output—completely isolating sensitive equipment like PLCs, DCS controllers, HMIs, and network switches from grid disturbances such as sags, surges, harmonics, and complete outages. With zero transfer time during power failures, it ensures continuous operation of mission-critical systems where even a millisecond interruption could trigger shutdowns or data loss.

Designed for integration into control panels and industrial enclosures, the SOLAHD S4K5U6K5W0BATC features a compact footprint, optional DIN rail mounting, and an extended operating temperature range of -20°C to +60°C—making it suitable for unconditioned environments like substations, pump stations, and remote oilfield skids. It includes built-in automatic bypass for added reliability, cold-start capability for battery-only operation, and comprehensive communication interfaces (USB, RS232, and optional SNMP/Web card) for remote monitoring and graceful shutdown. The SOLAHD S4K5U6K5W0BATC also comes with an integrated maintenance-free sealed lead-acid battery pack, enabling immediate deployment without external battery cabinets.

Technical Specifications

Main Features and Advantages

True online double-conversion for maximum protection: Unlike line-interactive or standby UPS systems, the SOLAHD S4K5U6K5W0BATC continuously powers the load from its inverter—even when utility power is stable. This eliminates all power anomalies before they reach connected equipment, providing military-grade power conditioning ideal for sensitive automation hardware. The pure sine wave output ensures compatibility with power factor-corrected (PFC) power supplies found in modern PLCs, servers, and industrial PCs.

Ruggedized for industrial deployment: The SOLAHD S4K5U6K5W0BATC is built to withstand extreme temperatures, high humidity, and electrical noise common in factories, water plants, and energy infrastructure. Its conformal-coated PCBs resist corrosion, while the wide input voltage tolerance reduces battery usage during brownouts—extending battery life. The unit supports cold start (battery-only startup), allowing control systems to boot during prolonged outages—a critical feature for remote unmanned sites.

Smart management and serviceability: The SOLAHD S4K5U6K5W0BATC includes automatic self-diagnostics, battery autotest, and predictive runtime estimation. Via USB or RS232, it integrates with PowerPanel Business software for event logging, email alerts, and automated shutdown of connected devices. Optional SNMP/Web cards enable browser-based monitoring and integration into enterprise SCADA or IT management platforms. Hot-swappable external battery packs (sold separately) allow runtime extension without powering down the system.

Application Field

The SOLAHD S4K5U6K5W0BATC is widely deployed in water and wastewater treatment facilities to protect PLCs controlling pumps, chemical dosing, and UV disinfection systems—ensuring compliance with environmental regulations even during grid instability. In oil & gas upstream operations, it safeguards RTUs, flow computers, and safety shutdown panels at wellheads and compressor stations where power quality is poor and site access is limited.

Manufacturing plants use the SOLAHD S4K5U6K5W0BATC to back up robotic controllers, vision inspection systems, and MES gateways on production lines where unplanned stops cost thousands per minute. Similarly, in renewable energy applications—such as solar farm combiner boxes or wind turbine nacelles—the SOLAHD S4K5U6K5W0BATC provides reliable power for communication gateways and pitch control electronics exposed to wide temperature swings.

Its compact size and DIN rail option also make the SOLAHD S4K5U6K5W0BATC ideal for retrofitting into legacy control cabinets originally designed without backup power. Across all these scenarios, the SOLAHD S4K5U6K5W0BATC delivers industrial-strength power resilience where commercial-grade UPS units would quickly fail.

Installation and Maintenance

Pre-installation preparation: Before installing the SOLAHD S4K5U6K5W0BATC, ensure adequate ventilation clearance (minimum 6 inches on all sides) to prevent thermal throttling, especially in enclosed cabinets. Verify that the input circuit can support the inrush current during battery charging (typically<30>DINRAILKIT-S4K firmly to a standard 35 mm TS-35 rail. Connect only grounded, shielded loads to the output receptacles or hardwired terminals, and avoid daisy-chaining power strips. For remote monitoring, install the latest PowerPanel software and test communication via USB or RS232 before commissioning.

Maintenance recommendations: The SOLAHD S4K5U6K5W0BATC performs automatic battery tests every 30 days, but manual verification is recommended quarterly using the front-panel LCD or software interface. Replace the internal sealed lead-acid batteries every 3–5 years, or sooner if runtime drops below 50% of rated capacity. Keep firmware updated via PowerPanel to benefit from diagnostic improvements. Never operate the S4K5U6K5W0BATC with damaged casing or exposed terminals. After any major power event, inspect logs for fault codes and validate bypass functionality. Always follow lockout/tagout procedures before servicing external battery packs.
