Founded in 1983, Yu-Sheng Electrical Enterprises Co., Ltd. is a manufacturer in the heavy electrical industry. With the products sold as important public works and project equipment and power equipment in Taiwan and around the world, the company has earned high reputation and popularity. The company has obtained the ISO 9001:2008/CNS 12681 quality certification of the Bureau of Standards, Metrology and Inspection, MOEA, and is a heavy electrical manufacturer registered as a "trademark" of the said institution. Since inception, "Yu-Sheng Electrical" has developed reliable power equipment to meet the demand for stable power in every country. In response to worldwide market needs, a branch was set up in Kunshan City, Jiangsu, China in 1999, and a factory was set up in Yixing City, Jiangsu in 2005.With the rapid and flourishing development of the high-tech industries worldwide, the development of various types of precision machines and equipment has expanded in scale. Relative to the precision mechanical equipment and processes such as IC semiconductor, CNC machines, precision laser cutting, EMS, PCB production equipment, PLC program control, microelectronics production, SMT, computer automation, etc., the high-tech industries' massive use of computer and precision equipment has led to power and voltage equipment's high sensitivity to power and voltage changes because excessive changes in the voltage are likely to result in abnormal operation, breakdowns, and even frequent ...

Krauler Voltage Stabilizers of VR-SD SeriesDo you remember those olden days when TV sets were large and black-and-white? At that time many homes had small black boxes next to their TV sets. TV sets were connected to them, and they, in turn, were connected to the mains. These boxes were called voltage stabilizers, and they served to protect TV sets and other electronic appliances from power surges in the network. Since then much time has passed, technologies have made a big step forward, and the quality of power supply has improved. Nevertheless, power surges that can damage electronics, even though they are quite rare, still may occur even in modern power supply networks. Besides, anyone may face the problem of a storm or a short-circuit.The device we're going to consider (Krauler's VR-SD) is an automatic voltage stabilizer and it is basically a descendent of those black boxes which once protected TV sets of our grandmothers and grandfathers against power supply instability. Being designed using modern technologies, Krauler VR-SD is able not only to level off power drops, but can also perform other functions to ensure quality power supply for the devices connected to it. This became possible due to the most reliable stabilization circuit - a circuit that uses a servomotor, which provides an ideally smooth voltage regulation, and supports devices with high starting currents, such as refrigerators, washing machines or electric drills.The stabilizer connects the load to the ...

VR-N series Voltage Stabilizers by Krauler The main reason that causes the laptops, computers, TV sets and other expensive equipment to break down is a voltage drop. It is well known that consumer devices are designed to be used at 220-230V. But the real voltage in the mains often varies from 150 to 280V. Voltage stabilizer is a device that automatically converts high/low voltage in stable 220V.There are three different power options for KRAULER stabilizers of the N series: 1000, 2000 and 3000 volt-amperes (VA). The higher the power value is, the higher are the total power and the number of various devices which may be connected to the stabilizer. The work of stabilizers of this series is based on a simple, but very effective relay circuit. On the left side of the device there is a LED display, showing the current value of voltage. The digital display is very convenient to control the input and output voltages, its indications are well read, even under fairly bright illumination. The display shows the input voltage. At voltages beyond the permissible values, the protection system activates. If the voltage drops below 140V, the LED indicator lights up the letter L, signaling of a low level of voltage. If the voltage exceeds the maximum permissible value, the letter H is displayed. In the case the voltage continues to increase, all the connected devices will be disconnected from the power supply to avoid faults and damages.There are five sockets on the reverse side, which ...

Krauler Voltage regulator VR-PR Series Krauler Voltage regulator VR-PR Series is designed to align the input voltage in the range from 140-260V to 220 V required for electrical appliances. The device is based on relay technology. The main advantages of this technology are as follows. First, there are no wearing parts, and therefore it has a great resource. Secondly, there is a high response speed (about 20 ms), ie the regulators are suitable for protection of computer equipment. Third, there are no distortions introduced into the external power grid, as well as low noise levels emitted by the regulator in operation, a small mass and size parameters, and high noise immunity.The special features also include an unusual new design. This voltage regulator is made in an elongated plastic casing, and the shape looks more like a surge protector. On the top panel there are five outlets with earthing (in Russia they are often referred to as "Eurosockets"). Rotation angle of the outlet is most convenient, since it is possible to use solid plugs simultaneously in all five outlet devices, for example, power supplies to household appliances.Next to the outlets there is a bright LCD as well as Display and Delay buttons. The former is to switch between the current input and output voltage on the display. The latter enables you to select the delay of voltage appearance at the output sockets (two values to choose from: 6 or 180 sec.). Three colorful indicators show the current status ...
