SSKE SC Series High-Frequency Online UPS (1K–10KVA) | True Online Double Conversion, 0ms Transfer, Pure Sine Wave for Servers & Critical Equipment
Product Overview
The SKE SC Series is a fully digital, high-frequency online UPS spanning 1K–10KVA. It uses true online double conversion to continuously condition incoming power, ensuring connected devices receive perfect, regulated AC power regardless of grid quality. Its compact, rack/tower convertible design (select models) and robust performance make it ideal for IT, industrial, medical, and commercial environments requiring 24/7 power stability.
Key Features & Benefits
True Online Double Conversion: 0ms transfer time, no interruption during power failures.
DSP Digital Control: Precise, stable performance with fast response to grid fluctuations.
Wide Input Voltage (110–300VAC): Operates reliably on unstable grids without frequent battery use.
High Efficiency: Up to 95.5% efficiency; ECO mode boosts savings to ~98%.
Active PFC: Input PF ≥0.99, minimizes harmonic distortion, lowers energy costs.
Pure Sine Wave Output: Compatible with all loads (servers, motors, sensitive electronics).
Intelligent LCD Display: Real-time status: load level, battery capacity, input/output voltage.
Comms & Monitoring: USB, RS-232, SNMP optional; remote management & auto-shutdown software.
Generator Compatible: Works seamlessly with backup generators (40–70Hz frequency range).
Full Protection: Overload, short-circuit, over/under-voltage, over-temperature, battery deep-discharge protection.
Flexible Battery: Internal (standard) or external (long-run) battery packs; fast recharge (~5 hours).
