SUG-DSO/DIN, surge protector dedicated to 100V speaker lines in DSO systems
SUG-DSO/DIN is a device that protects amplifiers and speakers in voice warning systems (DSO) and other radio node systems, where the standard signal is 100V line.
Low internal resistance, low insertion capacitance and the ability to transmit currents up to 5A have minimal impact on the transmitted signals.
The surge protector is designed to be mounted on a DIN 35mm rail. High-quality window terminals with high current load reduce the risk of damage during large shock impulses and temporary current overloads. The device occupies the width of one standard DIN module.
The product is recommended for installation at the boundary between LPZ0 and LPZ1 zones or higher.
Simplified internal diagram.
To ensure proper surge protection, it is recommended to use protectors at both ends of the cable and to properly ground them.
