Newly designed protection element for overvoltages and overcurrents with THREE protection levels. The protection cascade combines a high discharge capacity with an extremely short response time and ultra-fast current limiting, resulting in a superior protection effect.
NEW! Surge arrester and overcurrent protection in one module, certified for 5,000 amps (pulse class C2, tested at 10,000 V)
NEW! Clamping voltage only 10 V on the device side (after 1 µs)
NEW! Combination of three stages with a total of 12 protection and flashover paths
NEW! PE connection with very low contact resistance for uncut and low-impedance 2.5 mm² connection
NEW! Including two sets of terminals green, grey and orange for three-pole connection of D+, D- and GND
NEW! Now also available as SparPack or SuperSparPack with addition (one piece for five pieces or two pieces for 10 pieces)
This lightning protection module is designed for all RS-232 connections and bus systems regardless of the protocol used with them:
This RS-232 surge arrester of category C2 / Type 2 according to IEC 61643-21 is intended for installation in distribution cabinets and junction boxes in dry residential and business premises, control cabinets in industry and automation systems. It serves as a surge arrester between electrical conductors of the RS-232 bus system and the equipotential bonding rail in case of direct and near lightning strikes as well as overvoltages from switching operations, and discharges the partial lightning current into the earthing system.We recommend combining it with a surge arrester for power supply networks Type 1 and Type 2 and using several of these RS-232 BlitzART modules in the system.
This module is designed for all RS-232 bus systems without restrictions.
Note: This module has three protective effects, which differ depending on the connection side. The power stage acts on the bus side of the module and can equalise or dissipate 5,000 amps. Both connection sides are connected via a three-pole overcurrent protection stage. The downstream ultra-fast fine stage initially acts on both connection sides at the start of an overvoltage event, but as soon as the overcurrent protection stage is activated, the current flow between the two sides is limited so that the voltage equalisation of the fine stage only has an effect on the device side (as long as the event lasts) and drastically reduces the terminal voltage there again. For details, please refer to Function and Effect below.
The capacitive load of the two data lines of the RS-232 connection by this surge arrester is approx. 400 picofarad.
Surge arrester type 2 for RS232 with three-stage protection system with disconnection of the current flow to the equipment side.
This surge arrester can discharge 5,000 amperes (8/20 µs, pulse category C2, fast rising edge). In addition, this protection system is equipped with the innovative ElabNET Current-Cut technology (self-resetting high-speed fuse 1µs). This enables additional protection even against low overvoltages (e.g. short-circuit with 48 V due to wiring errors).
This BlitzART protection system is thus a combined protection system consisting of a very powerful type 2 surge arrester plus a very sensitive overcurrent protection (200 mA / 1 µs). Within one microsecond, the overcurrent protection switches off a possible damaging current to the unit side which could still occur due to the remaining protection level of the other two stages. The reset after the overcurrent event occurs automatically within one millisecond.
This short-circuits overvoltages, compensates potential differences and additionally separates remaining overcurrents. Due to this special combination, the achievable equipment protection is at least ten times better compared to conventional protection systems without this third protection level.
