Industrial Control System Power Supply Solution

The industrial control system power supply solution is suitable for various industrial control equipment: 1) PLCs (Programmable Logic Controllers): power supply for CPU, I/O modules, and communication modules

2) Inverters: power supply for control boards, drive circuits, and communication interfaces

3) Industrial controllers: power supply for MCU, sensor interfaces, and actuator drives

4) Sensor nodes: power supply for smart sensors and transmitters

5) Actuators: power supply for solenoid valves, relays, and motor drives. This solution is particularly suitable for 24V industrial bus powered equipment and can be directly connected to industrial site 24V power supply systems.

Industrial control equipment with 24V power supply can use this solution, specific configuration adjusted according to power requirements.

Different modules in the solution have isolation voltages designed according to application requirements: 1) 1500VDC: suitable for general industrial control applications such as sensor power supply and communication interface isolation, meeting industrial control system isolation requirements

2) 2500VDC: suitable for applications with higher isolation requirements such as power monitoring and high-voltage equipment control, providing higher safety margins. The benefit of this graded design is optimizing cost while meeting safety requirements, without needing all modules to use the highest isolation level. For special applications (such as medical equipment), 3000VDC isolation modules can also be selected.

General industrial applications: 1500VDC is sufficient; power systems: recommend 2500VDC; medical applications: select 3000VDC.

Solution power consumption and efficiency performance: main power supply B2412S-6W efficiency 86%, input power approximately 7W at 6W output

auxiliary power supply A2412S-2W efficiency 85%, input power approximately 2.4W at 2W output

auxiliary power supply A0505S-1W efficiency 82%, input power approximately 1.2W at 1W output. When the total output power of the entire solution is about 10W, the total input power is about 12W, with comprehensive efficiency of about 83%. This efficiency level is considered good in industrial power supplies, meaning power loss of about 2W, with controllable heat generation. For industrial equipment running for long periods, high efficiency can reduce energy consumption and cooling costs.

Solution comprehensive efficiency is about 83%, which is considered a good level in industrial power supplies.

The solution provides comprehensive protection functions: 1) Input overvoltage protection: automatic protection when input voltage exceeds rated range

2) Output overvoltage protection: shuts down output when output voltage abnormally rises, protecting the load

3) Output overcurrent protection: limits current or shuts down when output current exceeds rated value

4) Short circuit protection: enters protection state when output is short circuited, automatically recovers when short circuit is removed

5) Overtemperature protection: automatically shuts down when module temperature exceeds threshold, recovers when temperature decreases. These protection functions ensure that the power supply system and load are not damaged under abnormal conditions, improving system reliability.

Comprehensive protection functions ensure safe and reliable system operation.

Solution EMC performance design: 1) Conducted emissions: compliant with EN 55032 Class B standard

2) Radiated emissions: compliant with EN 55032 Class B standard

3) Electrostatic discharge: compliant with IEC 61000-4-2 Level 4 (±8kV contact/±15kV air)

4) Fast transient: compliant with IEC 61000-4-4 Level 4 (±2kV)

5) Surge: compliant with IEC 61000-4-5 Level 3 (±1kV). The power modules and isolated transceivers used in the solution have passed relevant EMC testing. For applications with strict EMC requirements, it is recommended to add external EMI filters and protection devices.

Solution complies with industrial-grade EMC standards, for strict EMC applications recommend adding external filtering.

Methods to adjust the solution according to actual power requirements: 1) Small power applications (<5W): use A2412S-2W as main power supply, A0505S-1W as auxiliary power supply

2) Medium power applications (5-15W): use B2412S-6W as main power supply, multiple A2412S-2W as auxiliary power supplies

3) Large power applications (>15W): use multiple B2412S-6W in parallel or select larger power AC-DC modules

4) Multi-channel output requirements: add corresponding number of A0505S-1W or other voltage level modules. Contact our FAE team, we can provide customized solution configuration according to your specific power requirements.
