4. Comprehensive Protection Mechanisms: Beyond basic protections such as Short Circuit Protection (SCP), Overvoltage Protection (OVP), and Overload Protection (OLP), the SDR-240 may also feature Over-Temperature Protection (OTP), ensuring automatic output cutoff under abnormal conditions to prevent damage.

5. International Certifications: These products typically pass multiple international safety certifications, including CE, TÜV, among others, assuring product quality and safety for global market applications.

6. Adjustable Output Voltage: Some models might offer output voltage fine-tuning, allowing users to adjust the voltage output according to specific needs, increasing flexibility.

Applications:

• Industrial Automation: Provides stable DC power for PLC controls, sensors, actuators, and other industrial automation equipment.

• Security & Surveillance: Powers CCTV cameras, access control systems, alarm systems, and other security devices, ensuring 24/7 uninterrupted operation.

• LED Lighting: Suitable for indoor and outdoor LED lighting systems, particularly for LED strips and fixtures requiring constant voltage drive.

• Telecommunication Equipment: Supplies power to routers, switches, wireless access points, and other telecommunications infrastructure, ensuring data transmission stability.

• Instrumentation & Control Systems: Used in various measuring instruments, automation control systems, providing power for controllers, displays, etc.

• Medical Devices: While not all SDR-240 models are suitable for medical devices, certain certified models can be used for auxiliary power in medical instruments such as monitoring devices and small-scale therapy equipment.

Note	1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.  2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.  3. Tolerance : includes set up tolerance, line ragulation and load regulation.  4. The power supply is considered a component which will be installed into final equipment. The final equipment must be re-confirmed that it still meets EMC directives.  5. Installation clearances : 40mm on top, 20mm on the bottom, 5mm on the left and right side are recommended when loaded permanently with full power.In case the adjacent device is a heat soure, 15mm clearance is recommended 6. Derating may be needed under low input voltage. Please check the derating curve for more details. 7.Please contact with SMUN customer service for more details.
