Minuteman Launches Ruggedized UPS for
Para Systems, Inc. has released
the Minuteman ERS1500RTNC, a
ruggedized uninterruptible power
supply (UPS) designed to provide
protection to support traffic control
and monitoring equipment, servers,
telecom equipment, VoIP systems,
security systems and a variety of
The ERS1500RTNC is a line-interactive unit with a capacity 1,500
VA and 1,050 W. The UPS is designed to efficiently operate in
extreme temperature environments. The ERS1500RTNC's expanded
temperature range is suited for use in extreme temperature and
humidity installations where a standard UPS would be unable to
function. High temperature batteries and temperature-compensated charging combine to provide an operating temperature range
from 5°F to 122°F, making the ERS1500RTNC an choice for backing
up equipment with extreme installation parameters. Additionally,
each unit has conformal coating on all electronic components that
resists corrosion in high humidity installations.
A rugged LED display that shows power status and operational
mode is a standard feature. As an additional bonus, each unit is
installed with an SNMP management card for remote management
and monitoring over a LAN. Minuteman's SentryPlus monitoring
and management software is also included. All ERS1500RTNC units
are covered by a 1-year parts and labor warranty and $100,000
Minuteman Platinum Protection Plan.
T12-MSM Circuit Breaker with Design Appeal
Schurter has released the T12MSM, a combination of a reliable
circuit breaker and a robust metal
switch. With its actuating appeal, the
T12-MSM can be stylishly displayed
on the front of the system as opposed to being hidden in the back.
Schurter combines its circuit breakers, with thermal operation (T12) and
thermal-magnetic operation (TM12),
with its MSM series metal switches.
The MSM switches are recognized
for their visual appeal and operating characteristics. Both the
switch housing and the actuator are fabricated from high-quality
stainless steel, and are available with mounting diameters of 19 mm
and 22 mm. The actuator and circuit breaker are supplied separate.
The switch mounts with a threaded neck. A coupler adjoins the
circuit breaker to the switch.
Switching voltage is 240 VAC/ 28 VDC with a rated current from
50 mA to 16 A (15 A UL). It is suited for use in a temperature range
of -5°C to 60°C and comes equipped with auxiliary contact or
shunt terminal as well as quick-connect or screw-clamp terminals.
The T12-MSM offers a variety of design options including an assortment of colors for ring or point illumination, as well as options for
standard or custom inscription.
The T12 and TM12 are reliable circuit breakers with positive
trip-free operation. The contacts open even if the reset button is
manually held in the closed position. They reliably protect equipment with rated currents from 50 mA to 16 A. The optional magnetic release protects against increased risk of short circuits.
With a vandal-proof design, IP 64 tightness protection and IK 07
impact resistance, the T12-MSM is also suited for outdoor applica26

tions and use in harsh environments. The look and feel is novel and
stands out among other circuit breakers as a true designer piece,
suitable for mounting on the front side of the equipment where
aesthetics is paramount.
Victron Energy Launches Battery Balancer
Victron Energy has launched its new battery balancer. Not all
batteries are created equal, and when multiple batteries are combined to create one large battery bank, the small differences between the batteries can cause problems that substantially shorten
the life time. The battery balancer prevents this by actively correcting the imbalance. Besides correcting, it is also equipped with an
alarm function to give a warning in case of a large deviation.
Batteries can be used in both series strings and series/parallel
banks, be they 24 V, 48 V or sometimes higher voltages. When using a series string or series/parallel bank to create differing voltages
and Ah ratings from individual 12 V batteries, you can end up with
a variance in terminal voltages on each battery. This will cause the
batteries to become unbalanced.
This situation is often made even worse by the seemingly ever
increasing demands on batteries, to run power hungry equipment.
The consequence of all this is that an expensive string or bank can
fail prematurely, which is costly in both time and money. Correcting and preventing battery imbalance with the Victron battery
balancer is the answer to extending the lifetime of batteries.
Emerson Network Power Increases Capacity of
High Efficiency Liebert eXL UPS Line
Emerson Network Power
has extended the capacity of
the Liebert eXL family of large,
transformer-free UPS systems
with the introduction of the
Liebert eXL 1,200 kVA/kW
UPS, as well as upgrades to the
previously released 800 kVA/
Designed for co-location
facilities and large enterprise data centers, the Liebert eXL UPS
1,200 kVA is available in single module and 1+N (distributed
bypass) multi-module systems, providing a choice of applications
to best meet business needs. The Liebert UPS helps data centers
maximize operational efficiency and increase PUE by delivering
efficiency up to 97 percent in double conversion mode, with a
potential savings of up to $12,000 per year over competitive technologies. Flexible configurations and capacity-on-demand with
Softscale technology help data center managers conserve capital
by enabling them to limit their initial investment, while allowing
them to rapidly expand capacity.
Softscale technology allows the Liebert eXL UPS to provide
capacity-on-demand, initially sized to current power requirements
and easily scaled to a larger capacity without adding footprint. The
Liebert UPS can also parallel up to six units to increase capacity
and redundancy. The unity power factor rating of the Liebert eXL
UPS enables it to provide more usable power to address computing demand for modern IT loads, thereby eliminating the need to
oversize the UPS. The larger capacity rating means that systems can
be designed with fewer modules, reducing cost, complexity and
possible points of failure.
The Liebert eXL UPS includes an integrated 10.4 inch color human machine interface (HMI) touchscreen which enables operators to see unit status at a glance, and provides detailed information making it easy to understand, diagnose and control the UPS.
