AEG ZAE105 Industrial Grade Power Supply Surge Protection Module
- Product Introduction: This is a dedicated industrial grade power supply surge protection module of AEG, designed for protecting AEG Modicon PLC systems and other industrial control equipment from damage caused by power supply line surges and transients such as lightning strikes and grid fluctuations. It is installed at the power input end of the industrial control cabinet, with fast response speed and high surge absorption capacity, which can clamp the surge voltage on the power supply line to a safe range, and is an essential safety protection accessory for industrial control equipment in harsh power grid environments.
- Technical Specifications:
- Protection Circuit: Three-stage surge protection circuit (gas discharge tube, varistor, TVS diode), multi-level absorption of surge energy.
- Protected Voltage: 24 VDC (for PLC system power supply), compatible with 115/230 VAC input power supply of industrial power supplies.
- Surge Absorption Capacity: 20 kA (8/20 μs impulse current), 10 kA (10/350 μs lightning impulse current).
- Response Time: ≤1 ns, ultra-fast response to clamp surge voltage in time.
- Clamping Voltage: ≤36 VDC for 24 VDC side, effectively limiting the surge voltage to the safe working range of PLC equipment.
- Insertion Loss: ≤0.1 dB at 50/60 Hz, no impact on the normal power supply of the equipment.
- Power Supply: No additional power supply required, powered by the protected power supply line.
Detailed content
-
- Operating Temperature: -40°C to +85°C; Storage Temperature: -50°C to +90°C; Protection Rating: IP20.
- Dimensions: 40mm × 100mm × 70mm (W×H×D); Mounting: Standard 35mm DIN rail mounting, series installation at power input end.
- Connection Method: Screw terminal, suitable for 0.5-4 mm² wire, rated current 20 A.
- Functional Features:
- Three-stage multi-level surge protection circuit design combines the advantages of gas discharge tube (high surge capacity), varistor (fast response) and TVS diode (ultra-fast clamping), realizing comprehensive absorption and clamping of different types of surges and transients on the power supply line.
- Ultra-fast response time (≤1 ns) can quickly clamp the surge voltage on the power supply line to a safe range before the surge energy damages the industrial control equipment, ensuring the safety of the internal circuit of the PLC and other control equipment.
- High surge absorption capacity (20 kA 8/20 μs) can withstand large lightning impulse and grid surge current, adapting to industrial sites with severe lightning strikes and unstable power grids such as outdoor industrial equipment and coastal areas.
- Low insertion loss (≤0.1 dB) has no impact on the normal power supply voltage and current of the industrial control equipment, ensuring the stable operation of the PLC and other control equipment during normal work.
- No additional power supply required, series installation at the power input end of the control cabinet, simple wiring and easy installation, no need to modify the original power supply circuit of the system, reducing the on-site installation difficulty.
- Built-in surge counter and status indicator, the surge counter records the number of surge impacts (up to 999 times), and the LED status indicators (green for normal, red for fault) display the working status of the module, facilitating maintenance personnel to check the surge impact situation and module status.
- Built-in thermal protection and overcurrent protection functions, when the module absorbs excessive surge energy and causes overheating or overcurrent, it will automatically disconnect the circuit to prevent the module from being damaged and avoid the spread of faults to the subsequent control equipment.
- The module is made of industrial-grade high-temperature and high-voltage resistant components, with a wide operating temperature range (-40°C to +85°C), which can work stably in various harsh industrial environments such as low temperature, high temperature and high humidity, with high reliability and long service life.
- Compact narrow width design saves the installation space of the industrial control cabinet, and the standard DIN rail mounting design is convenient for on-site installation and disassembly, suitable for installation with other industrial power supply and protection modules.
- Application Scenarios: Widely used for the power supply surge protection of AEG Modicon PLC systems and other industrial control equipment in various industrial fields such as factory automation, process control, municipal engineering, outdoor industrial equipment and intelligent building control systems. It is especially suitable for industrial sites with severe lightning strikes and unstable power grids such as coastal areas, mountainous areas, power plants and metallurgical factories, and is an essential safety protection accessory for ensuring the stable and reliable operation of industrial control equipment in harsh power grid environments.
