Due to the adjustment of the world's lighting electrical industry structure, the company has developed into a group, the international division of labor has been further refined, and the focus of its production and export trade is shifting to Asia. The export of lighting electrical products in China has developed rapidly in recent years and has been exported to more than 130 countries and regions on five continents, mainly in the United States, Germany, the United Kingdom, Southeast Asia and the Middle East. The trade volume in the past 10 years has increased almost 10 times. . However, it should also be noted that China's exported lighting electrical products are still in the lower grades in the international market, and quite a part of them are based on price. Understanding the consumer demand and laws and regulations of overseas markets and occupying the international market with high-quality products is the main task of China's lighting electrical appliance manufacturers. The entry of luminaire products into the European market requires compliance with the “Low Voltage Directives 73/23/EEC and 93/68/EEC†and the “EMC Directive 89/336/EECâ€. Among them, the low voltage directive is related to electrical safety requirements, and the electromagnetic compatibility (EMC) directive includes electromagnetic interference (EMI) and electromagnetic tolerance (EMS) requirements. In the specific implementation of product inspection, the directly cited inspection standard is the EU's integration standard. Taking the electrical safety of luminaire products as an example, the standard to be met is the EN60598 series, which consists of two parts: The first part of EN60598-1 is a general requirement for luminaires: Part III EN60598-2 is a special requirement. In addition, the lamps must also meet the requirements of the EU Electromagnetic Compatibility Directive 89/336/EEC. In addition to incandescent lamps, other lamps, especially fluorescent lamps, require EMC testing. The main items of the luminaire are as follows: 1. Structural inspection means whether the internal and external design of the luminaire is reasonable. For example, if the distance between the two contacts is large enough, it will not cause breakdown; the replaceable parts (light bulbs, etc.) are easy to replace, and no danger occurs; Wires should not be placed in sharp corners, interfaces or lighting, etc., so as not to cause friction of insulated wires; metal fixing nuts can not cross line parts. Second, the insulation performance lamps can be divided into Class I, Class II, Class III according to the level of protection against electric shock. Class I: Not only basic insulation, but also grounding wires, which can be touched by conductive parts without the risk of conduction when the basic insulation is invalid. Class II: Safety protection measures with basic insulation and double insulation or reinforced insulation. Class III: Use a safety extra low power supply to prevent electric shock. The safety extra low voltage is 42V or less. Third, the temperature rise test Temperature rise test is a relatively complex and time-consuming test, but it is essential. In the experiment, select the location where the heat is most heated, such as wire joints, bulb contact parts, screws, etc., and test the temperature rise curve of each point. In the experiment, the accessible parts of the luminaire, the insulating material, the internal wiring or the installation environment could not form a temperature that would affect safety. In addition, there is a temperature rise experiment under abnormal working conditions, that is, measuring the temperature rise of the luminaire under simulated fault conditions, the purpose of which is to ensure that the home is safe. In this case, the temperature of the components, internal wiring and mounting surface of the luminaire must not exceed the standard values. Durability Experiment The durability test of the luminaire is also one of the specified test items, that is, the luminaire is continuously operated. Quantitative indicators vary from product to product, such as 240 hours for incandescent lamps and 168 hours for fluorescent lamps, as specified by the standard. 5. IP test outdoor lights for outdoor lights, such as garden lights, street lights, floodlights, pool lights, etc. must also be IP tested. The IP rating refers to the dustproof and waterproof rating of electrical equipment and consists of two digit codes: The first digit indicates that solid foreign objects are prevented from entering the interior of the equipment: The second code indicates that water is prevented from entering the water. The IP level of the outdoor light is generally at least to meet the requirements of IP3. There are several ways in which the certification process proves that the luminaire product meets the above-mentioned EU regulations and technical standards. For Chinese lighting export enterprises, the most effective method is to apply for product certification to the certification body officially authorized by the EU, and obtain the right to use the famous certification mark. A series of certifications for decorative lights. Lighting products, especially decorative lights, are often introduced in a series of ways. Designers use the color, shape and material of the lamp to try to maximize the consumer. If each product is certified, the workload is high and the certification fee is high. Therefore, the company can apply to the certification body for “series certification of lampsâ€.

A manual pulse generator (MPG) is a device normally associated with computer numerically controlled machinery or other devices involved in positioning. It usually consists of a rotating knob that generates electrical pulses that are sent to an equipment controller. The controller will then move the piece of equipment a predetermined distance for each pulse.
The CNC handheld controller MPG Pendant with x1, x10, x100 selectable. It is equipped with our popular machined MPG unit, 4,5,6 axis and scale selector, emergency stop and reset button.
