Victron Current Electricity Transformer 100a: 50mA for Multiplus-II 1M
TheCurrent Electricity transformer 100 A: 50 mA from Victron Energy is an extension to the Multiplus-II / Multigrid II series. With the transformer, the PowerControl and Power Assist function can be implemented and the self-consumption with external current measurement can be optimized.
Characteristics
For multiplus II and multigrid II series
Cable length: 1m
Max. Electricity: 32a
Easy installation with a connector connection
PowerControl - optimization of the power supply with limited alternating currentThe Multiplus-II / Multigrid-II can give a very high charging current. This means a heavy load for alternating current supply or the generator. For this reason, a maximum current can be set. The Multiplus-II then takes into account the already adjacent consumption and only uses the still free electricity for battery charge.
Power Assist-extended usage options of generator or land connection: the "support" functionWith this function, the PowerControl principle receives a new dimension because the Multiplus-II can support a too weak alternative source. Load tips often only occur for a limited period of time. In such a case, the Multiplus-II ensures that an excessive current network or generator output that is too weak is immediately compensated for by energy from the battery. If the load is reduced, i.e. consumers are switched off, the energy that is sufficiently existing can then be used again for charging the batteries.

Switching station for the US230/12 12A 2700W 230VAC network
Versatile multi -talent
Offgridtec switching stations enable you to operate 230V consumers from two different voltage sources. Typically, this is a voltage converter or the public power grid
With the priority circuit, you can determine which power source should be used preferentially - this voltage source is eliminated to the replacement current source.
The use of the highest quality relay guarantees on the one hand a particularly precise switching threshold, on the other hand, your voltage converter is optimally protected from feedback from external tension.

VICTRON Filax 2 Transfer CE 230V/50Hz-240V/60Hz
The ultra -fast Filax transfer switch from Victron Energy (MPN SDFI0000000) was developed to switch important or sensitive consumers such as computers, industrial control units or modern entertainment electronics from one change of alternating current to another. The main source is typically the power grid, a generator or a land connection. An inverter usually serves as an alternative source. With its switch -off time of less than 20 milliseconds, even sensitive loads continue to work without interruption.The Filax is not designed to supply household appliances with high electricity consumption, such as washing machines or electric motors.Gun switching functionThe Filax is a transfer switch with a gun (non -bridge) switching function. The maximum time for switching the loads is 16 ms. The load is usually supplied with the main generator and is switched to the alternative source in the following cases:
The voltage of the main power source falls below the threshold value.
The frequency of the main power source falls below the low frequency threshold value or it exceeds the high frequency threshold value.
Switching back from the alternative power source to the main source of the main power as soon as the voltage and frequency values of the main source of the main power are located for 30 seconds within the limit values specified for switching back.Technical specifications

The Texu400 offers crucial advantages both in the self-made motorhome self-construction and the professional manufacturer:
saves over 50% installation space Compared to the use of conventional products,
Costs less money By unique merging functions in a single device and reducing the need for expensive raw materials (especially copper)
Less time and sources of error Due to the elevation of half of all cable crimples!
Texu400 central electrics for travel vehicle and boat
The Texu400 revolutionizes electrical installation. It combines different components that have been bought individually in a round overall housing, the use of space and the number of possible connections in the smallest space. The special arrangement, which is only available in the Texu400, enables system integration with groundbreaking low effort. This results in a drastic cost, time and space saving while reducing sources of error and maximum application comfort after installation.
Costs less
The Texu400 replaces the purchase of several expensive individual components. The unique, round arrangement in a single device also leads to a large saving of raw materials. Above all, the consumption of the strongly increased copper in the price could be reduced drastically.

Saves space
The elimination of individual components and the patented design in a round shape not only saves money - it also requires much less installation space in travel vehicle or boat. Extensive, electrical systems can therefore be planned in a smaller room and the space obtained can be used for other purposes.
Saves working hours & sources of error
Instead of many individual components, only a single component is installed, which "incidentally" makes half of all cable crimples superfluous! It saves valuable working hours and other installation material. 50% less crimples also mean 50% less stress with compounds that (now or later) can cause problems. The complete installation is less prone to interference in one fell swoop.
Furthermore, stacking of cable shoes and inadequate mass distribution is finally a thing of the past. Compared to a angular structure with individual components, 46% of a valuable space in travel vehicles or boot is stored!

Victron Anti-Islanding Box 63a, for one and three-phase operation
The anti-Islanding box is a completely pre-cabled and easy-to-install device, which ensures that your battery system can be continued in the event of a network failure.If theoretically energy could be fed back into the public network from a battery system in the event of a network failure, an anti-Icelanding device must be installed in the battery system that corresponds to the local provisions. If there is a power failure in the electricity plant, this so -called ENS separates the connection to the network and its system continues as an independent system.
The anti-Islanding Box 63a one and three-phase, is a combination of an anti-Icelanding device, the UFR1001E anti-Icelanding relay, two inline shifting devices and one main performance switch. It is suitable for both single -phase and three -phase systems. It has a nominal output of up to 63 A per phase and all parts are conveniently housed in a housing of the protection class IP65.
The anti-Islanding box can be integrated into a network-sponsored inverter/charging system (ESS) in order to meet the local anti-Icelanding regulations.
The anti-Islanding Box 63a for single-phase and three-phase systems fulfills the following standards:
- G83/2 and G59/3 (proof of conformity Great Britain)
-VDE-AR-N 4105 (proof of conformity na protection Germany)
-ÖVE / ÖNORM E 8001-4-712 (Austria's obstruction)
-DIN V VDE V 0126-1-1 / A1 / NOI-RES_13E (objection certificate of Europe)
-NRS-097-2-1 (proof of conformity in South Africa)
The German, Austrian and French norms require two electrical switchgear switched in a row.
The Ziehl relay controls both switching devices.Note: The second shooter is not required for G83 / 2 and G59 / 3-compliant systems.
