Parallel Units up to 40kVA
Businesses today rely on absolute system availability and scalability. The Must® Power EH Parallelable, N+1Redundant On-line Uninterruptible Power Supply (UPS) provides the ideal solution. The EH Series UPS can easily be configured using individual  6, or 10kVA models, providing up to 30kVA with N+1 redundancy.Alternate parallel configurations of 6 to 40kVA are achievable if N+1 redundancy is not required.

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.

N+1 Redundancy Ensures Reliability
If your equipment has to operate without interruption or downtime, the N+1 configured Must UPS is the clear choice. Should an individual UPS require maintenance, the UPS is automatically sensed and taken offline. The user is notified through the LCD display and an audible alarm.The unit may be serviced or replaced without the remaining UPS(es) or connected load having to be powered down. Internal UPS batteries are user-replaceable and hot-swappable, again while the UPS(es) and connected equipment are in full operation.

Plus Microprocessor Control with DSP
Must Power EH UPS has been designed using advanced Digital Signal Processing (DSP) microprocessor technology. DSP technology yields the highest level of internal UPS protection, control, performance and reliability.

Plus Frequency Converter Ready
The EH UPS Plus is easily programmed for use as a 50Hz or 60Hz frequency converter, making the EH Series UPS Plus the ideal choice for worldwide power applications.

Plus RS-232, USB & SNMP/HTTP UPS Management
With the supplied WINpower® software, all models support unattended shutdown, UPS management, data logging and a power diagnostic tool. The software supports all Windows® platforms including Vista, as well as Novell NetWare® 5 & 6, LINUX and FreeBSD. UPSilon for UNIX is available at an additional cost and supports most popular UNIX platform and OS versions.Must optional SNMP/HTTP agent board provides TCP-IP addressable remote management and monitoring over any 10/100 Ethernet LAN, WAN or the Internet. The agent board installs via a communications expansion slot located on the back of every EH Series model. Client software is supplied that supports the shutdown of multiple workstations and servers via the network.
