Product Description
Kinbo Technology UPS (Uninterruptible Power Supply) is an uninterruptible power source with an energy storage device, primarily consisting of an inverter, providing constant voltage and frequency. When the mains power input is normal, the UPS stabilizes the mains power and supplies it to the load. At this time, the UPS functions as an AC voltage regulator while also charging the internal battery. When the mains power is interrupted (power outage), the UPS immediately converts the energy stored in the internal battery through the inverter and continues to supply 220V AC to the load, ensuring the load operates normally, protecting both software and hardware from damage, and preserving data. UPS devices typically provide protection against both excessively high and low voltages.

Modular Uninterruptible Power Supply (UPS)
The product capacity covers power ranges from 1KVA to 10KVA, allowing users flexible configuration. The standard unit is mounted in a 19-inch standard network cabinet. This series of UPS can address almost all power issues, such as power outages, high mains voltage, low mains voltage, instantaneous voltage drops, voltage sag, high voltage pulses, voltage fluctuations, surge dips, harmonic distortion, noise interference, and frequency instability. It is widely used in broadcasting, high-speed ETC, medical distribution, industrial robots, 3D printing, military, and other critical fields.

Product Features:
① Offline operation, significantly reducing heat generation;
② The main circuit has no components that work continuously online, resulting in low failure rate and long lifespan;
③ Uses innovative inverter technology, fully isolating the DC power source from the AC load side, ensuring safety and durability;
④ High load rate, capable of reaching 100% load capacity;
⑤ Short switching time, with standard products switching within 10ms, and fast-switching products within 5ms.Intelligent battery charging and discharging management with an innovative charging method. The charging mode is a smart four-stage process: "current-limited 1.initial charge - constant voltage intermediate charge - fixed voltage float charge - intelligent intermittent online supplemental charge." The ISPS charger can adjust charging parameters according to different environmental conditions to provide optimized charging, extending battery life.
2. Excellent electrical performance, with overall efficiency up to 96%, reducing energy loss. Strong overload capability: 120% load can operate normally for 10 minutes; 150% load can operate normally for 1 minute; also equipped with output short-circuit protection.
3. Safe and reliable, ISPS devices operate in backup mode without continuous heat generation, functioning intermittently, usually requiring only simple ventilation. Since this project uses outdoor cabinets and outdoor temperatures in summer are relatively high, a low-power cabinet air conditioner is sufficient for heat dissipation.
