(I) Fun??es de Gerenciamento da Fonte de Alimenta??o
Entrada de Tens?o de Amplitude Larga e Saída Estável
O DEIF PSM-1 é compatível com vários tipos comuns de tens?es de entrada, incluindo diferentes níveis, como CA 220V - 480V e CC 24V - 220V. Essa adaptabilidade a tens?es largas permite que ele seja aplicado com flexibilidade em vários ambientes de energia complexos. Em termos de saída, ele pode fornecer uma saída de energia CC de 24V de alta precis?o e estável, com uma precis?o de tens?o de até ±1%, oferecendo suporte de energia estável e confiável para o equipamento conectado e garantindo o funcionamento normal do equipamento em diferentes condi??es de trabalho. Por exemplo, em algumas linhas de produ??o automatizadas com requisitos extremamente altos para estabilidade de energia, a saída estável do PSM-1 garante o controle preciso do equipamento de produ??o e evita erros de produ??o causados por flutua??es de tens?o.
Convers?o de Energia Eficiente e Recursos de Economia de Energia
Esse módulo adota tecnologia avan?ada de convers?o de energia, com uma eficiência de convers?o de energia superior a 90%, o que reduz consideravelmente a perda de energia durante o processo de convers?o. Através de um projeto de circuito otimizado e algoritmos inteligentes de gerenciamento de energia, o PSM-1 pode ajustar dinamicamente a potência de saída de acordo com a demanda real da carga. Ele reduz o consumo de energia próprio em condi??es de carga leve para alcan?ar uma opera??o econ?mica de energia.

Mecanismo Abrangente de Prote??o da Fonte de Alimenta??o
Para lidar com várias situa??es anormais que podem ocorrer no sistema de energia, o PSM-1 está equipado com fun??es abrangentes de prote??o da fonte de alimenta??o. Ele tem capacidade de prote??o contra sobretens?o: quando a tens?o de entrada excede o limite de seguran?a definido (por exemplo, CA 550V ou CC 250V), ele pode cortar rapidamente a saída de energia para evitar danos ao equipamento a jusante causados por tens?o excessivamente alta. Ao mesmo tempo, ele também tem fun??o de prote??o contra sobrecorrente: quando a corrente de saída excede o valor nominal (por exemplo, 5A), ele ativa automaticamente medidas de limita??o de corrente para evitar falhas de equipamento ou riscos de seguran?a, como incêndios, causados por corrente excessiva. Além disso, o PSM-1 também é integrado com fun??o de prote??o contra curto-circuito. Assim que um curto-circuito for detectado no terminal de saída, ele pode cortar a fonte de alimenta??o em um tempo extremamente curto (menos de 1ms) para proteger a seguran?a do equipamento e de todo o sistema de energia. Em um incidente de falta de energia em uma fábrica, uma corrente alta repentina foi causada por um curto-circuito na linha externa. A fun??o de prote??o contra curto-circuito do PSM-1 foi ativada rapidamente, impedindo com sucesso que uma grande quantidade de equipamento na oficina fosse danificada pelo impacto da corrente de curto-circuito e reduzindo enormes perdas econ?micas para a empresa.

Generator Set Control System
In various types of generator sets, such as diesel generator sets, gas generator sets, and wind turbine generator sets, the DEIF PSM-1 plays a crucial role. It is responsible for collecting various operating parameters of the generator set, such as the engine speed, oil temperature, oil pressure, and the generator's output voltage, current, frequency, etc., and conducts real-time monitoring and analysis of these parameters. By communicating with the controller of the generator set, the PSM-1 can adjust the operating status of the generator set according to the monitored parameters to achieve precise control of the generator set. For example, in a diesel generator set, when the load suddenly increases and causes the generator's output voltage to drop, the PSM-1 will feed back the voltage signal to the controller in a timely manner. The controller adjusts the throttle opening of the diesel engine according to the preset control strategy, increases fuel supply, and raises the engine speed, thereby restoring the generator's output voltage to the normal level. At the same time, the PSM-1 can also perform real-time diagnosis of faults in the generator set, such as engine overheating, low oil pressure, generator short circuit, etc. Once a fault is detected, it immediately triggers an alarm and takes corresponding protective measures, such as shutdown protection, to ensure the safe operation of the generator set and reduce equipment damage and maintenance costs.

The DEIF PSM-1 can be installed in the intelligent power distribution cabinet to conduct comprehensive monitoring of various power parameters in the cabinet, including incoming line voltage, current, power factor, and the current and electricity consumption of each outgoing line circuit. Through real-time monitoring and analysis of these parameters, the PSM-1 can promptly detect potential fault hazards in the power distribution cabinet, such as line overheating, overload, short circuit, etc., and upload the fault information to the power distribution automation system through the communication interface to realize remote monitoring and management of the power distribution cabinet. Operation and maintenance personnel can view the operating status of the power distribution cabinet in real time through the software interface of the monitoring center, and take timely measures for maintenance and overhaul, improving the reliability and safety of the power distribution system. For example, in the power distribution system of a commercial complex, the PSM-1 is installed in the power distribution cabinets on each floor to monitor power parameters in real time. When the current of an outgoing line circuit in a certain floor's power distribution cabinet suddenly increases beyond the rated value, the PSM-1 immediately sends an alarm signal and uploads the fault information to the monitoring center. The operation and maintenance personnel rush to the scene quickly based on the alarm information, identify that a short-circuit fault has occurred in a device connected to this circuit, and handle it promptly. This avoids a large-scale power outage caused by the expansion of the fault and ensures the normal operation of the commercial complex.
Power Quality Monitoring and Governance
Power quality issues, such as voltage fluctuations, harmonic pollution, and three-phase imbalance, will have a serious impact on the operation of equipment in the power system, reduce equipment service life, and even cause equipment failures. The DEIF PSM-1 can be used as a power quality monitoring device to conduct high-precision collection and analysis of signals such as voltage and current in the power system, and monitor power quality parameters in real time. Through the analysis of these parameters, the PSM-1 can accurately determine the power quality problems existing in the power system and provide corresponding governance suggestions. For example, when high-order harmonics are detected in the power grid, the PSM-1 can send control signals to the harmonic governance device through the communication interface, activate the harmonic filter, govern the harmonics, and improve the power quality of the power grid. At the same time, the PSM-1 can also record and statistically analyze the power quality data for a long time, providing data support for the power sector to formulate reasonable power quality improvement measures. In some electronic manufacturing enterprises with extremely high requirements for power quality, after using the DEIF PSM-1 to monitor and govern the power quality, the equipment failure rate is significantly reduced, the production efficiency is significantly improved, and the normal production of the enterprise is effectively guaranteed.

By communicating with equipment such as programmable logic controllers (PLC) and industrial computers, the PSM-1 can realize comprehensive monitoring and management of the automated production line, ensuring efficient and stable operation of the production line. For example, in the automated assembly production line of an automobile manufacturing enterprise, the PSM-1 collects the operating status signals of the equipment at each assembly station in real time. When a fault is detected in the equipment at a certain station, it immediately stops the production line and sends the fault information to the maintenance personnel. At the same time, the PSM-1 can also adjust the operating parameters of the equipment according to the product model and production process requirements on the production line, realizing flexible production of the production line and improving production efficiency and product quality.
Factory Energy Management System
In factory energy management, accurately grasping energy consumption and conducting reasonable optimization are crucial for reducing production costs and improving energy utilization efficiency. The DEIF PSM-1 can be used as a data collection and analysis device for the factory energy management system. It collects power parameters of various energy-consuming equipment in the factory, such as motors, lighting, and air conditioners, and monitors energy consumption in real time. Through the analysis of these data, the PSM-1 can generate energy consumption reports, analyze energy consumption trends, identify links with energy waste, and provide energy-saving optimization suggestions. For example, through the monitoring of the power parameters of the factory's lighting system, the PSM-1 finds that the lighting in some areas is still on when no lighting is needed during the day. By linking with the lighting control system, it realizes automatic control of the lighting switch according to the ambient light, thereby greatly reducing lighting energy consumption.
