1. Product Overview

      Different from rack-mounted and modular small-medium power UPS, the EPKL series adopts an integrated independent vertical tower cabinet structure, specially developed for large fixed load scenarios with stable long-term continuous operation demand. The whole machine uses full digital DSP high-frequency rectifier and inverter architecture, realizing full isolation of input, output and DC bus circuit, greatly improving anti-surge, anti-harmonic and anti-grid fluctuation performance under severe industrial power environment.

      All models are uniformly equipped with 10.4-inch ultra-wide viewing angle industrial touch color screen, supporting multi-language switching, real-time full electrical parameter browsing, fault waveform capture, historical operation log storage and export. Operators can complete parameter modification, load monitoring and equipment self-inspection on the local screen without connecting external monitoring terminals, reducing auxiliary equipment matching cost.

      This series supports up to 9 units parallel redundant operation, flexible construction of N+1, N+X backup power system, capacity can be expanded by adding single tower equipment without replacing the whole power room layout. The built-in multi-stage intelligent cooling air duct matches variable-frequency fan group, automatically adjusting wind speed according to internal temperature and load rate, balancing heat dissipation efficiency and running noise, suitable for 24-hour unattended industrial plant and large computer room operation environment.

2. Core Competitive Advantages

2.1 Independent Vertical Tower Cabinet, Stable Heavy-Duty Structure

      Integrated thickened steel tower cabinet, independent internal partition layout for rectifier, inverter, power transformer and control loop, strong anti-vibration performance, adapt to factory production workshop, outdoor machine room and other complex placement environment.

      Reserved independent wiring channel on cabinet top and bottom, separate input, output and battery wiring areas, avoid line crossing interference, convenient for engineering wiring and later circuit overhaul.

      Single machine integrated design, no need to splice multiple power modules, lower system fault points, simpler whole machine maintenance logic for large power station operation and maintenance team.

2.2 Full DSP High-Frequency Double Conversion, Premium Power Quality

2.3 Dual-Mode Energy Saving Operation, Ultra-High Comprehensive Efficiency

      Standard online double conversion mode efficiency ≥96.8%, intelligent ECO bypass energy saving mode peak efficiency up to 99.2, effectively cut down annual power consumption of large power station.

      Low no-load loss design, the standby power consumption of single machine is far lower than traditional low-frequency industrial UPS, long-term operation greatly reduces enterprise energy expenditure.

      Intelligent variable frequency cooling system, fans only run at high speed under high temperature and full load; low load and low temperature state run at low speed, reduce running noise and extend fan service life.
