Liebert 40 KVA UPS System ...

We offer you today a very clean and well maintained Liebert Npower 40 KVA UPS System with two matching Battery Cabinets. ( NOTE: Batteries not included and can be purchased at a discounted rate) This UPS System has been maintained with annual and semi annual preventive maintenance. The UPS has a full Internal Maintenance Bypass feature that allows for load isolation and come with Network Communication Cards that alerts customer of any issues with the UPS while allowing them the ability to view to full functions of the UPS systems at all times. 

The Liebert Npower can be as simple or complete as you need

it to be. With matching battery cabinets, that can be a bolt-together system.

All bolt-on cabinets have casters and leveling feet, to

simplify installation.

Smallest Complete-System Footprint

The Liebert Npower achieves a small footprint despite

being a full-featured, double-conversion UPS.

Furthermore, Liebert understands that real systems

have battery cabinets, maintenance bypass cabinets

and some type of power distribution cabinets.

Therefore, our design goal was to build complete

systems, in all their variant forms, in the smallest

practical size consistent with good engineering

practices. Consider this:

■ No size penalty for 208 VAC input or output. For each

kVA rating, all input voltages and all output voltages

fit in the same size package.

■ Input isolation and bypass isolation transformers fit

inside the same package.

■ Battery trays slide out the front for maintenance.

Liebert has built advanced monitoring and communications capabilities

into the Liebert Npower UPS system. Liebert monitoring and control

products allow you to take full advantage of these features. You will find a

full range of monitoring and control systems, communications modules and

other equipment designed to interface with a variety of communication

protocols, operating platforms and building management systems.

Knowing what is happening with your power equipment, so you

can keep it at peak operating efficiency, is vital to system reliability.

Thank you and have a safe Day,

CT Analyzer

Product Features
1.  5.7inch LCD screen display.
2.  Full functions, satisfy all kinds of CT(protection CT, measuring CT, TP) test requirements, such as excitation characteristic test, turn ratio, polarity, secondary winding resistance, secondary burden, ratio error, angular difference and etc. Also it can be used to test excitation characteristic, turn ratio, polarity, secondary winding resistance,ratio error, angular difference and etc all kinds of PT.
3.  More efficient to test CT, no need to use standard CT, primary current injection device, load case, voltage   regulation control and high current lead to verify the CT.
4.  Meets IEC60044-1, IEC60044-6 standards of all kinds of CT/PT.
5.  Accurately measure ratio error and angular error. Max. Ratio error ±0.05% is permitted. Max. Angular error ±2min if permitted. It can measure 0.2S class CT and turns ratio range is 1-35000.
6.  Auto test CT/PT parameters on knee point voltage/current, 5% and 10% deviation curve measurement,  Accuracy limit factor (ALF), safety factor (FS), second time constants (Ts), residual magnetism factor(Kr),  saturated and unsaturated inductance.
7.  Using variable frequency method to test VA curves and 10% error curve of CT/TP. Max. Output is 180V and 5A rms(15A peak value), but it can make CT test when keen point is up to 60kV.
8.  Easy to use. To test CT DC resistance, excitation and polarity only by one button. All CT tests adopt same     one connect method except load test.
9.  Storage 1000 groups data, data can be saved even power down. Equipped with micro printer to print test result after testing completed.
10. Test results can be download by USB disk.
11.  Small size, weight is no more than 10kg, suitable for on-site use.
