48V DC Power Surge Protection

SUG-48VDC is a surge protection device designed to protect electronic devices powered by 48V DC from atmospheric discharges, voltage surges, and sudden voltage spikes that may occur due to damage to the power supply.

The ability to transmit up to 3A of current allows for use in most industrial automation installations, building automation, and property protection systems.

High-quality window clamps with high current load limit the risk of damage during large shock impulses and momentary current overloads. Thanks to its small size, it does not take up much space and can be hidden in small enclosures or electrical boxes.

The device has 2 protected power supply tracks and a protected screen circuit. This solution can be used in installations where it is necessary to shield the power supply from electromagnetic interference.

The product is recommended for installation at the boundary between LPZ0 and LPZ1 zones or higher. It can only be used for transmitting 48V DC voltage, without any AC component - for example, for high-speed data transmission. It is connected between the power source (power supply, battery) and the receiving device.

To ensure proper surge protection, it is recommended to use limiters at both ends of the power line and properly ground them.
