2.High efficient and energy saving

• Compared to the mode adopting AC generator with switch power, the DC gasoline generator has higher completion set efficiency, and can save above 30% gasoline, which complies with national industrial policies for energy conservation and environmental protection.

3.Safe and reliable

• HEGEN DC generator sets adopt unique high efficient generator technology with low-voltage design, which can avoid personal injury and equipment damage under extreme situations. The set has functions to protection output overvoltage, set over-temperature, battery polarity reverse, short circuit and engine oil low level so as to guarantee long-term stable and safe working of equipment.

4. Intelligent design

• The sets can flexibly set the battery volume and load size and intelligently match the output voltage aiming at situations of various base stations. The sets adopt latest switch power system technology to guarantee the battery charging complies with the optimal charging curve of the battery, and meanwhile can automatically/manually adjust floating charge and constant current (constant voltage) by referring to current and voltage information. While guarantee the battery is full, the battery service life can be effective improved.

5.Flexible parallel operation

• When charging the large-volume base station power supply and battery, the two or more DC generators can be used in parallel without being limited by models and quantities. Each generator set can independently set the output current regardless the problem of equalized flow output. The parallel function can select the generator sets and quantities with corresponding power according to the loads, which can greatly improve the motility of the equipments and meet the supply requirement for various conditions flexibly and conveniently.

6.Direct load

• The output power indexes of the generator can fully meet the requirement of YD/T731-2008 Standards for Communication High-Frequency Switching Rectifier, and direly supply power to the load. The generator set is in a leading position in key indicators of voltage stabilization precision, telephone balance weight noise and peak-to-peak value.

7.Comprehensively adaptive

•The specifications are complete including 30A, 50A, 100A and 200A series products, which can meet the requirements of various base stations for charging and maintenance. The output voltage of the generator set covers 24V, 48V, 110V and 220V, which can fully adapt to various application scenarios of DC load.

8.Humanized, toolized

• The generator sets have functions of long generation time, generation volume statistics, log record and export, which are for the convenience of management and maintenance.

Both men and women are worth the US best replica rolex watches online with cheapest prices and high quality.
The AAA perfect replica watches for US with Swiss movements are of high quality.
