Key Features of a Static Transfer Switch (STS):

1. Seamless Transfer: The STS can switch between power sources without any interruption in power supply, typically in a matter of milliseconds. This is essential for mission-critical applications.

2. Automatic Operation: It can automatically detect a failure or anomaly in the primary power source and switch to a backup source without human intervention.

3. Static Technology: Unlike mechanical transfer switches, STS utilizes solid-state devices such as thyristors or IGBTs (Insulated Gate Bipolar Transistors) to make the transfer. This reduces wear and increases reliability since there are no moving parts involved.

4. Monitoring and Control: Many STS units come with built-in monitoring and control capabilities, allowing operators to assess the status of both power sources and the performance of the switch.

5. Load Management: Some STS systems can prioritize loads and manage power distribution based on predefined criteria, ensuring that the most critical loads receive power first.

   The 48Vdc/220Vdc series of 48Vdc and 220Vdc Static Transfer Switch converts 48VDC/20Vdc power from a communications DC power supply into 220V/50Hz sinusoidal DC power. Both the input and output are isolated, and can be used for hot swapping or parallel redundancy. It is small in size and can be connected in parallel. This power supply is ideal for users who have high expectations for reliability and maintenance.
