The 250 VAC PCB Mountable Solid State Relay (SSR) is an electronic switching device used to control high voltage AC loads through a low voltage DC control signal. This type of relay is designed for easy mounting on printed circuit boards (PCBs) and is widely used in automation, control systems, and various industrial applications.

Features

• Rated for 250 VAC, suitable for controlling various AC loads.
• Utilizes semiconductor devices to switch loads, providing faster response times and improved reliability compared to traditional electromechanical relays.
• Designed for direct installation on PCBs, making it ideal for compact applications and space-saving designs.
• Provides electrical isolation between the control and load circuits, enhancing safety and reducing the risk of damage to control components.
• Operates with a low DC control voltage (often 3-32 VDC), allowing for easy integration with microcontrollers and other low-voltage devices.
• Some models feature zero-crossing technology, reducing electrical noise and inrush current during switching.
• Typically includes a heat sink or has a thermal management design to ensure efficient heat dissipation during operation.
