Excavator B7-6 (EX-CAT-340)


The Cat® 340 excavator delivers efficiency in all applications. Simple-to-use technologies like Cat GRADE with 2D, Grade Assist, Payload, and E-Fence all come standard from the factory to boost your operator efficiencies up to 45 percent. Combine these with a new cab, longer maintenance intervals that lower your maintenance costs up to 15 percent, and a power system that that improves fuel efficiency up to 15% and you have a low-cost-per-unit-of-production excavator capable of taking on your toughest work. Not all features available in all regions. Consult your Cat dealer for specific configurations available in your region.

Data Center Backup Generator (Gen-dc-19)

Managers of data centers offering collocation and cloud services sign contracts guaranteeing 100% up-time. Most engineering types would say that's impossible; however, that kind of guarantee is the cost of doing business in today's market. If the service is anything less than 100%, clients get substantive refunds, and the data center loses credibility.

That could explain why data-center operators will spend millions of dollars on backup power-generation equipment, which more often than not amounts to diesel generator sets similar to the Cummins model pictured above.

To learn more about how these monsters work, I contacted the Cummings Power-Generation Business Unit, which is the division that builds generator sets of all sizes, from Oman RV models on up. At the division headquarters in Minnesota I met Richard Hallahan, Technical Marketing Manager for Data Centers and a certified professional engineer, and he ushered me into a high-tech conference room and asked how he could help.

Automatic Transfer Switch (ATS) ABB 125A (Pw-ats-125a-abb)

Automatic Transfer Switch (ATS) is used which alternating current is no more than
660VAC,and the direct current is 250v.the rated frequency is 50 Hz. The ATS rated current
series is 40A, 63A, 125A, 160A, 200A, 250A, 400A, 630A, 800A, 1000A, 1250A.be divided
up two types with 3 poles and 4 poles. 40A, 63A, 125A, with 2poles.The ATS of 40~125A
is defined with ‘N’; 160~630A is defined with ‘T’; above 630A is defined with “M”.


Air temperature
1) maximum temperature less than+40 Celcius2) minimum temperature is more than
3) The daily maximum temperature less than +35Celcius atmospheric moisture relative
humidity no more than 50% when the maximum temperature is +40Celcius the monthly
maximum relative humidity is 90%can bear humidity from the sea .
Install elevation the elevation of the installation site l less than 2000 m, when used
in the higher sea level, should be consider air dielectric strength
and the cooling effect will be reduced.
Pollution degree the installation site of pollution degree is 3
Installation gradient the installation of ATS onto cabinet, the gradient not more than
(plus-minus) 25Celcius
Flashover distance the flashover distance is 80mm as the alternating current is 380v,
when 660v.the distance is 100mm

SGQ_ ATS CONTROL MODULE ISSUE 2010-02-03 Version 1.0 Page 4 of 9


SGQ and ATS use solenoid coil driving, electric apparatus as linked at same time. The
major loop contact terminals are two static loads, one dynamic Load used “V” tape design.
The “M” type used UNICOIL direct current supply pulse operation, to avoid magnetic coil
under long Operations with live line work.”N” and “T” type used 2 coil direct current supply
pulse operation. The power switching in controller Main power AC220v without other
control power after electromagnetic driving, mechanical electrical linked under connecting
to avoid switching device for main and standby power sources communicated at the same
time so that aroused error.the switch has electric and Mechanism close instructions as
segregation of functions indicator.we also supply two normal open and two normal closed
passive secondary contacts for use of others


SGQ and ATS as main double loop power supply and automatic transfer switch mainly
used for first order load which under state specified standards. it also adapted to
mansion,communication, coal mine and ship,industrial assembly, health and medicine,
military equipment and so on . The main switching power also can be network, auto
starting generator and storage battery, or set by customers. ATS switching time within
80ms.customers can delay according to practical .when the main power and standby
power supply at the same time, the main power preferred.
