Uninterruptible DC/AC power supplies with pure sine output

IES offers a complete line of inverter that are designed to be integrated in power bays and closets, typically for telecom, industry, railway and medical uses.

Our inverter modules convert direct voltage into alternating sine wave voltage, with galvanic isolation. They integrate the latest-generation of power management electronics, giving you  the benefit of IES know-how for HF electrical energy conversion:

• Reduced size to facilitate integration, offering maximum power in minimum space
• Modules can be stacked without spacers
• Extremely high efficiency
• Reduced switching loss (resonance technology)
• Electromagnetic compatibility
  • Immunity: EN 61000 4-2/4-3/4-4/4-5/4-6
  • Output: ETS 300-132-2  CISPR 22 Class B

100% digital technology

Our fully digital technology offer the following highly desirable advantages:

• Hot-swappable for easy maintenance
• Parallel operation in redundant mode (N+1)
  • Up to 3 modules without supervision
  • Up to 16 modules with supervision
• Integrated bypass, programmable in off-line or on-line mode (“green power” standards)
• Supervision (monitoring)

Our standard inverter product line ranges from 500VA to 3000VA, 24V or 48V input current, for 19” racks, 1U or 2U formats.

All of our uninterruptible power supplies are available in standalone versions.
