EK3C20H 20kVA Industrial-Grade 3-Phase In Single-Phase Out High Frequency Online UPS

The EK3C20H (20kVA) is a true double-conversion online UPS designed to solve critical power challenges including outages, high/low voltage fluctuations, line noise, and frequency variation. With a 3-phase input (380V/400V/415V) and single-phase output (208V/220V/230V/240V) topology, it balances power loads across grid phases while providing stable, clean pure sine wave power for high-density IT infrastructure, industrial automation, and commercial facilities.

B2B Buyer Advantages & Core Features

• True Double-Conversion & 0ms Transfer: Guarantees instantaneous backup power (0ms transfer time from Utility to Battery / Inverter to Bypass) to prevent unexpected system shutdowns and data corruption.
• Advanced DSP Digital Control: Driven by high-speed DSP technology, delivering higher power density, smaller footprint, enhanced reliability, and lower total cost of ownership (TCO).
• Wide Input Voltage & Frequency Range (190V–520VAC / 45–65Hz): Operates smoothly under unstable grid conditions and remote environments, significantly reducing battery discharge cycles to extend battery lifespan.
• High System Efficiency (Up to 92%): Reduces overall energy consumption, operational heat dissipation, and long-term utility expenses for your end clients.
• Generator Compatible & Active PFC: Input power factor near 1 with PFC technology minimizes grid pollution and integrates seamlessly with diesel generator sets.
