With the development of microcontrollers and the maturity of measurement and protection technology, the application of traditional pumps in production automation and buildings has gradually shifted from the button indicator to an all-in-one intelligent controller (also known as universal pump control Device). In particular, all-in-one intelligent controllers are favored by the market for their functional requirements that meet the needs of information and intelligence. The Shanghai Ning Hong Electric Technology Co., Ltd. as the domestic high-quality industrial products manufacturing professionals in the field of its own R & D and production of universal pump controller in production and living automation applications have been made extremely efficient. NHK-2LP350S intelligent full-voltage start controller new pump controller Overview: NHK-2LP350S intelligent full-voltage start-up controller, is designed to market demand for water pump 0.55-15KW developed a new high-performance products, the main For sewage pump control box, deep well pump control box, regulator pump control box, feed pump control box as an intelligent control supporting the use of modern small pumps to achieve the optimal choice of intelligent control. The new pump controller has the function of a universal machine: First, the control method is universal; by setting the parameters can choose float control, electric contact pressure gauge control, pressure switch control, electrode probe control, electromagnetic probe control, fault pump change control , Rust and other control methods. Second, the power common; By setting the parameters can choose to control the power of 0.55-15KW motor, set the power should be consistent with the actual power of the motor, without adjusting the current (the controller automatically determine the rated current according to the rated power). Third, the common protection functions; By setting the parameters can be short-circuit, phase loss, stalling, overload, no load, dry turn, water, over voltage, under voltage, anti-rust impeller, three-phase unbalanced protection . Advantages of the new pump controller features 1, easy operation, stylish, dual digital dynamic display, indicating full, rich and perfect fault code prompts, so that the general pump room managers without going through complex training, but also on the various Operate freely, without the need for professional engineers to operate it. For installation and commissioning personnel, and telephone communication can handle the general failure, save time and easier to operate. 2, grouped parameter code to facilitate the debugging staff or users to accurately find the required setting parameters. 3, rust function, turn on this feature can be timed to start the inspection of the pump to prevent the pump does not work for a long time cause the pump easy to rust. 4, anti-time protection, the greater the load operating current, the greater the protection time is shorter, the smaller the running current protection time longer. 5, definite time protection function, the use of high-precision primary current transformer, instead of the traditional thermal relay to detect the load current, through the upper and lower current limit set to make its protection action, more accurate than the original motor protection, more stable, more reliable. 6, voice navigation function, through the voice of the entire product fault, operation, alarm voice to explain and enhance the overall grade of the product. At present, Ning Hong Almighty pump controller has been successfully used in Shanghai Panda, Shanghai Aoli, sea lions and other hundreds of pump industry leader in the process of product use.

Mini Ball Lens
Spherical ball lenses are commonly used for laser collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, and fiber-to-detector coupling. Larger spheres are easier to handle and ease the sensitivity of translational alignment. However, smaller spheres fit into smaller packages. The addition of a broadband MgF2 antireflection coating results in a highly efficient lens due to the high refractive index of the glass. Coupling efficiency is generally >90% due to the simplicity of these lenses.
We consistently offer various high quality optical components according to the customer's requirements. Such as prisms,Spherical Lens, aspherial lens,Ball lens,Optical Windows,Achromatic Lens,Cylindrical Lens,beamsplitters,mirrors,color filters,diffraction grating,reflectors,waveplates etc.
