GE D20-PS LFDSC143-4000

Overview

Technical Parameters

• Input Parameters: Supports AC input with an input voltage range of 110V AC - 240V AC, a frequency of 50Hz/60Hz, and a maximum input current of 3A. It is compatible with industrial power supply standards in different regions and can adapt to scenarios with large voltage fluctuations.
• Output Parameters: Provides multiple DC outputs, among which the main output is 24V DC with a rated current of 10A and an output power of 240W; it is also equipped with auxiliary outputs (such as 5V DC/2A, 12V DC/1A, subject to the actual model) to meet the voltage requirements of different devices in the system. The output voltage accuracy is ±0.5%, and the ripple coefficient is ≤50mV, ensuring the stability of the output power.
• Conversion Efficiency: The conversion efficiency under typical working conditions is ≥90%, which can effectively reduce energy loss, reduce the heat generation of the module, and improve the energy utilization efficiency of the system.
• Protection Functions: Equipped with overvoltage protection (triggered when the output voltage exceeds 115% of the rated value), overcurrent protection (current limiting or shutdown when the single-channel output current exceeds 120% of the rated value), short-circuit protection (quick shutdown when the output is short-circuited, automatic recovery after the fault is eliminated), and overtemperature protection (protection starts when the module temperature exceeds 75℃), providing all-round protection for itself and the load equipment.
• Environmental Parameters: The operating temperature range is -25℃ - +70℃, and the storage temperature range is -40℃ - +85℃; the relative humidity is 5% - 95% (non-condensing); the protection level is IP20, suitable for installation in control cabinets to resist dust intrusion.
• Physical Specifications: Adopting a modular design, the dimensions are approximately 200mm×150mm×80mm (length × width × height), with a weight of about 800g. It supports DIN rail mounting or panel mounting, saving installation space.
• Certification Standards: Complies with international industrial certifications such as CE, UL, and ATEX, meeting the safety and electromagnetic compatibility requirements of major global industrial markets.

Functional Features

• Wide Range Voltage Input: The wide input range of 110V - 240V AC enables it to adapt to the power supply networks of different countries and regions without additional transformers, reducing system integration costs, and is especially suitable for transnational industrial projects.
• Multi-Channel Output Adaptation: In addition to the main output of 24V DC, the auxiliary output can meet the low-voltage requirements of small devices (such as sensors and indicator lights) in the control system, reducing the number of external power supplies, simplifying system wiring, and improving the neatness of the layout in the control cabinet.
• Efficient and Stable Operation: High conversion efficiency not only saves energy but also reduces module heating and prolongs service life; high output voltage accuracy and small ripple provide clean power for sensitive electronic components (such as microprocessors and communication chips), avoiding equipment misoperation caused by voltage fluctuations.
• Comprehensive Protection Mechanism: Multiple protection functions such as overvoltage, overcurrent, short circuit, and overtemperature can quickly respond to power abnormalities or load faults, preventing module damage and fault spread to the entire control system, and improving the safety and reliability of the system.
• Strong Anti-Interference Ability: The internal multi-stage filter circuit and electromagnetic shielding design can effectively suppress electromagnetic interference (EMI) and radio frequency interference (RFI) in industrial sites. At the same time, the interference generated by itself meets international standards, avoiding interference to other equipment and ensuring the collaborative work of equipment in the system.
• Convenient Installation and Maintenance: The modular design and standardized installation method facilitate quick integration into the control system; the surface of the module is equipped with LED indicators, which can intuitively display the power working status (normal, fault), making it convenient for maintenance personnel to quickly judge the power operation status and shorten the fault 排查 time.

Application Fields

• Industrial Automation Control Systems: In the PLC control systems of production lines such as automobile manufacturing and mechanical processing, it supplies power to controllers, digital/analog I/O modules, human-machine interfaces (HMI) and other equipment, ensuring the stable operation of functions such as logical control and data collection of the production line, and guaranteeing the continuity of the production process.
• Power Industry: In substation automation systems, it provides power support for protection relays, measurement and control devices, communication gateways and other equipment. In high-voltage and strong electromagnetic interference environments, stable power output can ensure that the equipment accurately monitors power grid parameters and executes protection actions, ensuring the safe operation of the power system.
• Process Control Field: In DCS (Distributed Control Systems) of chemical, pharmaceutical and other industries, it supplies power to modules of field control stations, valve positioners, online analyzers and other equipment, adapting to high-temperature and dusty environments in production sites, and ensuring precise control of parameters such as reactor temperature and pressure.
• Intelligent Transportation Systems: In the signal control systems of rail transit and toll systems of expressways, it provides stable power for controllers, sensors, communication equipment, etc., resisting vibration and electromagnetic interference caused by vehicle driving, and ensuring the accurate transmission of traffic signals and the normal operation of toll systems.
• Energy and Environmental Protection Industry: In monitoring systems for wind power generation, sewage treatment and other scenarios, it supplies power to data collection terminals, actuators and other equipment, adapting to outdoor or humid environments, and ensuring real-time monitoring of parameters such as wind speed and sewage flow and remote control of equipment.
