Parallel Units up to 80kVA
Businesses today rely on absolute system availability and scalability. The Must® Power EH Parallelable, N+1 Redundant On-line Uninterruptible Power Supply (UPS) provides the ideal solution. The EH Series UPS can easily be configured using individual 10, or 20kVA models, providing up to 60kVA with N+1 redundancy. Alternate parallel configurations of 6 to 80kVA are achievable if N+1 redundancy is not required.ired.ired.
Stand-Alone Units Lower Costs
In contrast to most modular scalable Uninterruptible Power Supplies, the EH5000 Series are stand-alone units that may be connected in parallel. This economical approach eliminates the added expense of buying cabinets to house control, power and battery modules.
True Regenerative On-line Design
The EH Series True Regenerative On-Line UPS provides the highest level of protection against the widest spectrum of power problems. The incoming AC utility source is converted to a regulated DC voltage. From this DC voltage, a new AC voltage is generated, providing clean, tightly regulated power to your equipment.
