● Manufacturer Honey Vermey
Product Number :51196655-100
Product type :TDC 3000 power module
● All our power supplies are fixed for the internal line frequency clock. If the NIM requires event sequence (SOE) functionality, the clock host, clock slave, and NIM with SOE requirements must be fixed for use with an external clock. All other nodes are fixed to the internal (line frequency) clock. Jumpers are located at J102 and are clearly labeled (INT) and (EXT).
● Shipping weight :3 kg
1.TDC2000 produced many important achievements in the field of control systems at that time, such as redundant controller, redundant control network (DH-Data Hiway), man-machine interface, etc. According to the distribution principle, the basic function distribution of the whole TDC2000 is as follows: the control network adopts single-layer redundancy structure; Operation Responsible for operation and data storage; Different controllers realize different process control and so on. This basic function allocation is still used by some DCS control vendors.
2. As the most typical DCS system, TDC3000 further reflects the concept of decentralized control with the following main features to meet the needs of large-scale production, the use of two-layer control network architecture, each LCN can be connected to 10 UCNs, each UCN can be connected to 32 pairs of redundant controllers. 64 LCNS can also be connected via NG.
The power module is a power converter that can be mounted directly on the printed circuit board, which is generally divided into AC to DC or DC to DC according to the conversion method. With the development of science and technology, the volume of power supplies tends to be modular and miniaturized, so there is a power module. The main circuit of the switching power supply is integrated in the chip, which can realize the functions of broadband modulation, isolation and a variety of protection.
The common basic principle consists of the following parts, the input rectifier filter, including the rectifier bridge and the input filter capacitor. Single-chip switching power supply, including power switching tube, controller and MOSFETs, and high-frequency transformer, leakage clamp protection circuit, optocoupler feedback circuit, output rectifier filter, bias circuit and other parts.
The power module can generally adapt the input voltage range of AC 85~ 265V or DC 100~ 370V through the input rectifier filter, and the frequency is 47 ~400Hz, and the conventional is generally 50/60Hz. Because it has a small size, integration, high cost performance and the best performance indicators, only the simplest peripheral circuit is required, with a few discrete components can be used. And has the advantages of high efficiency, reliability, flexible design, etc., has become the optimal integrated circuit for the development and design of small and medium power switching power supply.
The selection of power module scheme has low technical requirements, simple design, small space occupation, high reliability, and can be exchanged at any time. When the product design needs to be changed, just parallel or replace the power module. Therefore, it is widely used in industrial control, machinery and equipment, ships, aerospace, communications, military red, data communication, handheld electronic products, instruments and meters, LED lighting, intelligence, electric power, railway, security, mining, medical automotive electronics and other fields.
A power supply module is a power supply that can be mounted directly on a printed circuit board and is characterized by providing power for application-specific integrated circuits (ASics), digital signal processors (DSPS), microprocessors, memory, field programmable gate arrays (FPgas), and other digital or analog loads.
Generally speaking, power modules are divided into two types: AC to DC or DC to DC. According to the conversion mode, it is divided into linear power module and switching power module. According to the use is divided into ordinary power module, special power supply. According to the function, it is divided into AC/DC power module, DC/DC power module, LED driver power module. According to the package, it is divided into pin jack power module and patch power module.
With the development of science and technology, the volume of power supplies tends to be modular and miniaturized, so there is a power module. The main circuit of the switching power supply is integrated in the chip, which can realize the functions of broadband modulation isolation and a variety of protection.
Power modules are widely used in many fields, such as switching equipment, access equipment, mobile communication, microwave communication, optical transmission, routers and other communication fields and automotive electronics, aerospace and so on.
