MEAN WELL 20W 48V DC 20A DRDN-20-48 power supply

    

Description of the DRDN-20-48 power supply:

The MEAN WELL DRDN-20-48 module is a device that provides power redundancy, which is crucial for the uninterrupted operation of electronic devices. Thanks to the ability to operate two separate power sources in parallel mode, this module significantly increases the level of system reliability by automatically switching to a backup power source in the event of a primary power failure. It is distinguished by high energy efficiency and the possibility of installation on a standard DIN TS35/7.5 or 15 rail. It also has additional options such as relay connectors and LED diodes that provide information about the current power supply status. This is the optimal solution for important systems that require reliable access to energy.

   

Description of the DRDN power supply series:

The MEAN WELL series of DRDN power supplies are advanced modules ensuring power redundancy, designed for mounting on a TS35 / 7.5 or 15 DIN rail. They are characterized by a metal housing cooled by open air circulation, which allows their operation at temperatures from -20 to -20 +70°C. Compliance with a number of standards and certificates and a three-year manufacturer's warranty are additional advantages of these devices. The offer includes models such as DR-RDN20, equipped with relay connectors and LEDs indicating the status of the power system.

   

DRDN series features:

  • Support for 1+1 and N+1 redundancy systems

  • 2 input channels and 1 output

  • Possibility of cascading power sources

  • Cooling by free air convection

  • -40~+80°C - very wide operating temperature range (derating by >+60°C)

  • Built-in 2-channel DC OK signal and alarm relay contact

  • Mounting on DIN TS35/7.5 or 15 rail

  • DRDN-20/40 modules use MOSFET technology

  • Output current up to 20A

  • 3 years warranty

       

Application of the DRDN-20-48 power supply:

The DRDN-20 module, also known as a power redundancy module, is a key element in many industrial sectors where the reliability and continuity of electronic systems are essential. Its use is wide and diverse, which makes it irreplaceable in many applications. Its main task is to maintain uninterrupted power supply to critical electronic componentseven in the event of a failure of one of the power modules. The DRDN-20 module is often used in various industries such as industrial automation, process control, as well as in medicine and other areas that require a stable energy source.

  • In industrial automation, the DRDN-20 module ensures the safety and efficiency of operations by maintaining continuity of power for machines and devices. In the event of a failure of one of the power supplies, the module automatically switches to the other power supply, preventing downtime and potential production losses.

  • In process control, especially critical ones such as chemical or pharmaceutical processes, the DRDN-20 module ensures that monitoring and regulation of processes are not interrupted, which is crucial to maintaining quality and safety standards.

  • In medicine, where equipment must function without interruption, the DRDN-20 module is used to power critical medical devices such as ventilators and patient monitoring systems. The reliability of this module contributes to the protection of patients' lives and health.

  • In other areas, such as telecommunications, data centers or security systems, the DRDN-20 module plays the role of ensuring the continuity of systems operation in the event of a power failure. This is especially important in situations where even a short-term power outage can lead to serious consequences.

In summary, the DRDN-20 module is a versatile solution that increases reliability and safety in many industries by providing a stable power source for critical electronic components. Its ability to maintain uninterrupted power supply, even in the event of a failure, makes it an invaluable element in any system where business continuity is a priority.
