DC surge protector for protecting data/signal lines, 12 V DC RSP-2L-12 2617111

DC Surge Protector for Data Line Protection

This compact device is designed to protect sensitive data and signal lines from the effects of surges in 12 V DC installations. It provides protection for two independent circuits, making it an ideal solution in automation, alarm, telecommunications systems, and anywhere reliable protection against interference is required. Fast response time – less than 1 ns for line-to-line surges – minimizes the risk of damage to connected devices.

Construction and Application

The RSP-2L-12 surge protector is designed for direct mounting on a standard 35 mm rail (according to PN-EN 60715), which simplifies and speeds up installation. Its small size allows for discreet placement inside control cabinets or distribution boards. Designed to operate in a wide temperature range, from -40°C to +80°C, it guarantees reliable operation even in harsh environmental conditions. The maximum continuous operating voltage of 14 V DC (9.5 V AC) ensures compatibility with most standard systems.

Key Features and Benefits

• Two-line protection: One device protects two independent circuits, reducing costs and simplifying installation.
• Fast response time: Response time of less than 1 ns (line-to-line) and 100 ns (line-to-PG) effectively suppresses surges, protecting sensitive components.
• Wide voltage range: Possibility of use in both 12 V DC and AC installations (from 9.5 V) increases the flexibility of the device.
• Temperature resistance: Operation in the temperature range from -40°C to +80°C ensures reliability in various environmental conditions.
• Easy installation: Direct mounting on a 35 mm rail simplifies and speeds up installation.
• Rated current: The device can withstand a load current of up to 0.5 A at 25°C.
• Impulse protection: Withstands current impulses with a value of 0.5 kA (10/350 μs).

The rated operating voltage is 12 V DC, and the maximum continuous operating voltage is 14 V DC for DC circuits and 9.5 V AC for AC circuits. The response time of the overvoltage protection is very short – less than 1 ns for line-to-line connections and less than 100 ns for line-to-PG connections. The device can operate at a temperature of -40°C to +80°C, and its rated current at 25°C is 0.5 A. It is also resistant to current impulses with a value of 0.5 kA (10/350 μs).

The RSP-2L-12 surge protector is a solid and effective solution for professionals and users looking for reliable protection of their electronic systems against the effects of surges.
