Apollo 3:1P15K-L 15000VA 3:1 Phase Online UPS

Apollo 3:1P15K-L 15000VA 3:1 Phase Online UPS in Bangladesh

The Apollo 3:1P15K-L 15000VA Online UPS is a high-capacity, true double-conversion power protection system designed for mission-critical three-phase power environments. With its 3-phase input (3P) and single-phase output (1P), this UPS is ideally suited for industrial setups, data centers, telecom base stations, and large commercial installations where three-phase utility power needs to feed single-phase load. The “-L” variant supports long battery backup by using a 384 V DC battery bank, allowing extended runtime during blackouts or grid instability.

In normal operation, the unit runs in online mode, converting input power to DC and then inverting it back to AC, offering continuous clean sine-wave output regardless of input fluctuations. Its wide input voltage range (typically 380–415 V AC ± adjustable) tolerates unstable supply lines while the zero (0 ms) transfer time ensures that critical systems never go offline during a power disruption. The UPS comes equipped with a high-visibility LCD panel to monitor input/output voltages, load levels, battery status, and historical events.

The 3:1P15K-L features built-in protection mechanisms, including overload protection (110% for 60 min, 125% for 10 min, 150% for 1 min), short-circuit protection, and over-temperature shutoff. Communications are facilitated via RS-232, RS-485, dry contacts, and optional SNMP card for networked monitoring. Additional features include a wide crest factor (3:1), modular system design, and customization options such as current-sharing inductors and harmonic filters. IP-rated chassis and safety compliance (IEC/EN standards) make it both powerful and robust.
