Product Descriptions

PCBA corrosion is one of the key reasons leading to UPS components failure, especially in coastal areas. APUS III applies advanced PCBA coating technology, offering customers an excellent anti-corrosion performance.

APUS III adopts the advanced 3-stage charging technology. In the first stage, it charges the battery up to 90% capacity with high current. In the second stage, it charges the battery to 100% capacity with constant voltage. In the third stage, it stays in rest mode. The 3-stage charging method can extend the battery life cycle avoiding long-time floating charge issues. An intelligent battery management technology can accurately forecast battery working mode and remind your customers of potential malfunction.

APUS III supports flexible battery quantity configuration. Customers possess flexibility to choose different battery capacity and quantity in the backup solution. Even in the on-run mode, the battery quantity con?guration can be quickly adjusted to disassemble the malfunctioning battery, while the whole UPS system can guarantee a constant power supply. APUS III could provide a maximum 80A charging current, 1h fully charge the lithium battery, Lithium battery charge/discharge capability 1C/$c for 80kVA model.

APUS III is embedded with internal parallel kits powering by high reliability CAN bus. With better output voltage regulation, perfect load sharing and active protection, APUS III assure the reliability and redundancy of the paralleling power system. APUS III offers more excellent performance in paralleling and improves the output accuracy also the Optimized Parallel Technology ensures UPS continued output without parallel cable, allows one-by-one maintenance without extra maintenance bypass switch. No Master-slave in the parallel system, eliminates single point of failure, enhances reliability.
