Core functions and features

3.1 Wide range adaptation and stable output

The module adopts advanced PFC (Power Factor Correction) technology, with a power factor of ≥ 0.95, effectively reducing harmonic interference to the power grid, and achieving wide range input adaptation of AC 85-264V. It can be directly applied to industrial sites of different voltage levels without the need for additional transformers. It adopts high-precision DC/DC conversion circuit and feedback regulation mechanism internally, even in the case of input voltage fluctuation of ± 10% or load variation of 50% -100%, the output voltage fluctuation is still controlled within ± 0.5%, providing stable power for the control system that is not affected by grid fluctuations and avoiding control logic disorder caused by voltage fluctuations.

3.2 Comprehensive redundancy and fault-tolerant design

Support multi module parallel redundant operation, up to 4 modules can work in parallel, and automatic load current sharing is achieved through the built-in current sharing circuit, with a current sharing error of ≤ 5%. When one of the modules fails, the remaining modules can automatically bear all the load, ensuring uninterrupted power supply and greatly improving the reliability of system power supply. It is suitable for critical industrial scenarios where shutdown is not allowed. In addition, the module has a "hot plug" function, which can replace faulty modules while the system is running without cutting off the main power supply, reducing system downtime.

3.3 Comprehensive state monitoring and diagnosis

The module is equipped with rich status indication and signal output functions. The front is equipped with a power indicator light (PWR), an output normal indicator light (OK), and a fault indicator light (FAULT). Staff can intuitively judge the operating status of the module through the indicator lights. At the same time, the module provides a DC 24V fault alarm relay output interface. When overvoltage, overtemperature, overload and other faults occur, the relay contacts will act and can directly link with the upper computer or alarm device to issue a prompt. Support uploading module operating parameters (such as input voltage, output current, module temperature) to the control module through the WES5100 series system bus, enabling remote monitoring and fault diagnosis.

3.4 Industrial grade reliability and durability

Adopting full industrial grade component selection, such as long-life electrolytic capacitors (with a lifespan of ≥ 50000 hours @ 40 ℃) and high-temperature resistant power devices, to ensure long-term stable operation of the module in harsh environments. The internal PCB of the module is treated with a three proof coating, which has the ability to prevent corrosion, moisture, and dust, and can adapt to highly corrosive industrial scenarios such as chemical and metallurgical industries. Its anti vibration performance meets the IEC 60068-2-6 standard (10-500Hz, 10g acceleration), and its anti impact performance meets the IEC 60068-2-27 standard (50g acceleration, 11ms duration), adapting to the mechanical vibration environment of industrial sites.

Installation and usage precautions

1. The module needs to be installed on a DIN 35mm standard guide rail, and the installation position should be away from devices with high heat generation (such as frequency converters and high-power resistors). A heat dissipation space of ≥ 10mm should be reserved around the module to ensure good heat dissipation;

2. Before wiring, it is necessary to confirm that the input power type (AC/DC) is compatible with the module. The input power line should use copper core wire with a cross-sectional area of ≥ 1.5mm ², and the output line should use copper core wire with a cross-sectional area of ≥ 2.5mm ² according to the load current. The wiring terminals should be tightened to prevent poor contact and heat generation;

When running multiple modules in parallel redundancy, it is necessary to connect the "current sharing" terminals of all modules to each other and ensure that the module model and firmware version are consistent to avoid module damage caused by abnormal current sharing;

4. The output of the module fault alarm relay should be correctly connected to the upper computer or alarm device for timely response to faults; When replacing modules, it is necessary to first disconnect the input power supply and wait for the capacitor to discharge (about 5 minutes) before operating to avoid the risk of electric shock;

5. Regularly maintain the module, check whether the input and output wiring is loose, whether the heat sink is dusty, and whether the indicator light status is normal. When the environmental humidity is high, it is necessary to strengthen the module's moisture-proof protection to extend its service life.
