True Regenerative online Uninterruptible Power Supply Design.
As new and innovative technologies have become the backbone of today's businesses, maximum system availability is critical and downtime
is more expensive than ever.Increasingly, businesses need an On Line UPS backup power supply that not only protects against blackouts,
but also virtually eliminates more frequent and subtle power disturbances. Surges, sags, line noise and brownouts can disrupt proper
operation of sensitive equipment. These disturbances may also create unnecessary production, service, and data recovery costs. Must UPS
solves these problems with high quality backup power supply solutions.

A True Regenerative On Line Uninterruptible Power Supply from Must 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 regenerated, providing continuous, clean, tightly  regulated power to your equipment.

Input Power Must Correction
All EH5000 Series UPS Must models include state-of-the-art Input Power must Correction. This greatly reduces the amount of current demanded from your building wiring - system, yielding a highly efficient, "building friendly" UPS.

Microprocessor Control
Must power EH5000 Series UPS incorporates advanced microprocessor technology. This technology makes possible a high level of internal UPS control and management. With the supplied software, all EH5000 Series UPS models support unattended shutdown, management, data logging, and self-diagnostics. The software supports MS Windows® 95, 98, NT, 2000, 2000 Server, ME, XP, Novell Netware® 5 & 6, LINUX and FreeBSD. UPSILON for UNIX supports most popular UNIX platforms and OS versions.
 

SNMP/HTTP Remote Management Support
Our SNMP/HTTP Agent board provides remote management and monitoring over any Ethernet LAN, WAN or the Internet utilizing a 10BaseT-type connection. The optional SNMP/HTTP agent installs via a port located on the back of every EH5000 Series model.

Extended Battery Ready
All EH5000 Series models have continuous duty inverters and support the addition of optional externalbattery/charger packs. Whether your application requires a few additional minutes or hours, the EH5000 Series is ready.

Frequency Converter Capability
With a factory modification and the addition of an external input transformer, EH5000 Series models can be configured for use as voltage and frequency converters. This makes the EH5000 Series UPS an ideal choice for worldwide power applications.

Must EH Series 1K, 2K, 3K UPS are connected through the RS232 communication port to Must Power Management software for power detection and power monitoring, to integrate UPS and the network server into one entity with power status available at any time.
