Newly designed protection element for overvoltages and overcurrents with THREE protection levels and one function level. The protection cascade combines a high discharge capacity with an extremely short response time and ultra-fast current limiting, resulting in an outstanding protection effect. One function level increases the range by means of a band-pass filter and BusBoost circuit.
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 24 protection and flashover paths
NEW! PE connection with very low contact resistance for uncut and low-impedance connection with 2.5 mm²
NEW! Including two sets of terminals blue, grey and orange for three-pole connection of 1-Wire (5V, GND, DATA)
NEW! Including bandpass plus BusBoost for extended range 1-Wire bus
NEW! now also available as a SparPack or SuperSparPack with extra (one piece for five units or two pieces for 10 units)
This lightning protection module is designed for 1-Wire bus systems with bus masters such as DS9490R and Loxone 1-Wire Extension. This module also contains a bandpass filter and ElabNET BusBoost technology for optimised 1-Wire range.
For use with the ElabNET Professional bus master or with the Timberwolf servers of the models 350Q, 950Q and 960Q, we offer a separate BlitzART protection module optimised for the higher current resistance of the PBM.
DIN / IEC 61643 certified lightning and surge protection system, tested for use in all 1-Wire bus systems with bus masters such as DS9490R and Loxone 1-Wire Extension. This protection module also contains a bandpass filter and ElabNET BusBoost technology for optimised 1-Wire range.
For use with the ElabNET Professional Busmaster or with the Timberwolf servers of the models 350Q, 950Q and 960Q, we offer a separate BlitzART protection module optimised for the higher current resistance of the PBM.
Note: For use with the ElabNET Professional Busmaster or with the Timberwolf Servers of the models 350Q, 950Q and 960Q, we offer a separate BlitzART protection module "1-Wire PBM" optimised for the higher current carrying capacity of the PBM.
The capacitive load of the data line of the 1-wire bus (DATA) by this surge arrester is a few picofarads, which corresponds to the capacitive load of less than 1 m of bus line.
Most important recommended additional measure: Have internal lightning protection (type 1 and type 2 arresters) for energy-technical networks installed on the low-voltage side.
Surge arrester type 2 for the 1-Wire with three-stage protection system with reduction of the current flow to the equipment side and additional functional stage to increase the range.
This surge arrester can discharge 5000 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), which provides additional protection even against low overvoltages (e.g. short-circuit with 24 V due to wiring error).
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 (50 mA / 1 µs). Within one microsecond, the overcurrent protection switches off a possible damaging current to the side of the unit which could still occur due to the remaining protection level of the other two stages. The reset after the overcurrent event takes place automatically within one millisecond.
This short-circuits overvoltages, compensates for potential differences and additionally separates remaining overcurrents. Due to this special combination, the achievable device protection is at least ten times better than conventional protection systems without this third protection level.
This 1-Wire 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 1-Wire 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 the combination with a surge arrester for power networks type 1 and type 2 as well as the use of several of these 1-Wire BlitzART modules in the 1-Wire system.
This module is designed for use with all 1-Wire bus systems (we offer an optimised module for use with PBM).
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 compensate or discharge 5,000 amperes. 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; once the overcurrent protection stage is activated, the current flow between the two sides is limited, so that the voltage compensation 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.
