The Su‑Kam 5 kVA UPS is a robust single‑phase online backup power system designed for commercial, industrial, or heavy‑duty residential loads, delivering roughly 4, 000 W of usable output. It features a pure sine wave output with DSP‑based control, often with galvanic isolation, which protects connected equipment against voltage spikes, harmonics, and other distortions. These units offer wide input voltage tolerance (e.g. ~170–280 VAC), fast and reliable switching between mains and battery, and multiple safety features like short‑circuit protection, overload sensing, and automatic bypass. Charging of the battery bank is managed in multiple stages (often six‑stage) to prolong battery life, with flexibility in battery capacity (e.g. 96 V or 180 V battery banks depending on model) to accommodate different backup time needs. The unit includes user‑friendly LCD display for status, load, battery levels and fault indications, and often communication ports (RS‑232 / RS‑485) for more advanced monitoring. Physically, it is built heavy, with good thermal management (forced air cooling), and sized in a way that makes it suitable for installation in server rooms, telecom equipment enclosures, or power backup rooms.
