APU series is an online UPS power supply produced by RINCK ELECTRONIC company. It has DC output voltage and is suitable for installation in distribution boxes or distribution boxes. The series has multiple input voltages, such as 230V, 48V, and 110V.
The A399 series uninterruptible power supply (UPS) from Rinck Electronic is designed for building, plant and safety technology applications. It features an online UPS architecture with DC output, integrated network filter, fuses and transient protection, and supports standard 230 V AC input as well as optional 24 V, 48 V and 110 V AC/DC inputs.
The device includes comprehensive protection functions (OVP, OCP, over‑temperature, short‑circuit, and output over‑voltage), optional redundancy (N+1), and a range of monitoring modules for battery voltage, current, and state‑of‑charge. Battery packs up to 18 Ah are supported, with under‑voltage cut‑off and automatic charging. Installation guidelines cover wiring, grounding, and cooling requirements.
