Detailed description

Skrinjasti preklopnik Masterswitch 25 kW 230 V od podjetja Mastervolt je osrednja odločitvena enota vaše izmenične električne napajalne mreže na krovu. Namenjen je nadomestitvi ročnega preklapljanja med dvema viroma izmeničnega toka, ta avtomatski preklopnik upravlja z močmi do 25 kW z maksimalno jakostjo 125 A tako na vhodu kot na izhodu. V nasprotju z osnovnimi preklopniki ta industrijski model zagotavlja neprekinjen prehod med generatorjem, vtičnico na obali ali pretvornikom s čudovito hitrim časom preklopa (12 do 22 ms pri vklopu, 4 do 19 ms pri izklopu).

Pametno upravljanje prioritet in varnost sistema

Masterswitch 25 kW ima dva vhoda izmeničnega toka in en sam izhod. Vhod 1 ima absolutno prednost in je idealen za povezavo z generatorjem ali vtičnico na obali. Da se ohrani mehanika generatorja in se zaščiti krovno omrežje pred nihanji napetosti in frekvence, je mogoče nastavljivo zakasnitev vklopa od 0 do 10 sekund (privzeto nastavljeno na 10 sekund), ki omogoča stabilizacijo generatorja pred prevzemom obremenitve. Vhod 2, ki ima sekundarno prednost, samodejno prevzame v primeru odsotnosti napetosti na prioritetnem vhodu, brez porabe lastne energije (0 W), ko se uporablja samostojno z pretvornikom. Ob maksimalni obremenitvi na vseh vhodih notranja poraba skrinjastega preklopnika ostaja minimalna pri 26 W.

Robustna izvedba za morsko okolje

V skladu z normo IP55 je ta skrinjasti preklopnik težak 3,8 kg (dimenzije 291 x 241 x 168 mm) izdelan tako, da odporen na vlažna okolja in ekstremne temperature (od -5 °C do 60 °C v delovnem režimu). Namestitev je olajšana z vmesniki, ki sprejemajo kable velikih presekov, od 4 do 50 mm² (AWG 10 do 1/0). Čeprav ni združljiv z omrežjem MasterBus in nima vgrajenih varovalk (v nasprotju z različico Masterswitch Fuses), njegova čisto elektromehanska zasnova zagotavlja absolutno zanesljivost za plovila, ki zahtevajo težko in varno energetsko upravljanje.

« Referenčni avtomatski stikalo za omrežja 230 V z visokim izhodnim tokom »

Preklopnik Masterswitch 25 kW je ključna komponenta za upravljanje visokih moči na krovu večjih enot. Njegova sposobnost, da vzdrži 125 A v kontinuiranem delovanju na omrežju 230 V, ga namenja težkim instalacijam, kjer je zanesljivost AC stikalne naprave kritična. Zlasti cenim mehanski nastavljivi časovnik do 10 sekund na prioriteto vhoda: to je nujna zaščita, ki omogoča čas za generatorju, da izravna svojo frekvenco pred napajanjem ladje. Čeprav nima vmesnika MasterBus, ta preprostost zagotavlja imuniteto proti komunikacijskim okvaram. Z velikimi klemenimi, ki sprejemajo kable do 50 mm², in ohišjem IP55, gre za industrijsko kakovostno opremo, zasnovano za trajno uporabo v življenju ladje, če je pravilno zaščitena z ustreznimi diferencialnimi stikali na vhodu.

Frequently asked questions

Need help? Contact us

What is the Masterswitch 25 kW box used for?

It is used to automatically switch between two alternating current sources (such as a generator and a shore power connection) to power the onboard electrical system, without any manual intervention on your part.

What are the maximum power and current ratings supported?

This industrial transfer switch can handle high power up to 25 kW, with a maximum current rating of 125 A on both input and output.

How many inputs and outputs does this box have?

The Masterswitch has two AC (alternating current) inputs to connect your power sources, and a single output that redistributes the current to your electrical system.

How does priority work between the two inputs?

Input 1 has absolute priority. If a voltage is detected there, it automatically powers the output. Input 2 takes over only when no current is present on Input 1.

Why is there a switching delay on the main input?

A 10-second default activation delay allows the generator to start up and stabilize its voltage and frequency before taking the load, protecting your onboard electrical system.

Is it possible to modify the activation delay?

Yes, this delay is adjustable from 0 to 10 seconds. If you use input 1 to connect a shore power plug (which does not require a warm-up time), it is recommended to set this delay to 0 seconds.

What is the switching time between the two power sources?

Transfer time is ultra-fast: expect 12 to 22 milliseconds on startup, and 4 to 19 milliseconds on shutdown.

Do computers risk shutting down during the switch?

Yes, due to the micro-outage inherent in the transfer between AC sources, computers and other highly sensitive electronic equipment may lose data if not protected by a UPS.

Is the Masterswitch housing waterproof?

Yes, it meets IP55 waterproofing standards, effectively protecting it against dust deposits and water jets in marine environments.

Is this switch compatible with the MasterBus network?

No, this specific model is not compatible with the MasterBus communication network.

Do we need to install external fuses or circuit breakers?

Yes, this box does not include circuit breakers. It is essential to install fuses and residual current circuit breakers (rated at a maximum of 125 A) on the wiring for all inputs and outputs.

What are the weight and dimensions of the device?

The device weighs 3.8 kg. Its exact dimensions are 291 x 241 x 168 mm (height x width x depth).

How should the grounding be performed?

The Masterswitch grounding terminal must be connected to the boat's or vehicle's central grounding (connected to the hull or chassis) to ensure the safety of the installation.

What are the tolerated operating temperatures?

The device is designed to withstand demanding conditions, with a specified operating temperature range from -5 °C to 60 °C.

What is the nominal voltage accepted by the switch?

It is designed for single-phase 230 V systems (with an input range of 200 to 250 V), operating at a frequency of 50 or 60 Hz.

Does the unit have LED indicators or a remote control?

No, this model is designed in a clean, industrial style: it has no LED indicators on the unit nor any port for remote control.

Where should I install the transfer switch onboard?

Although it is rated IP55, it must be installed in a dry location, protected from direct rain, snow, excessive humidity, and condensation risks to prevent any electric shock.

Can this switch be used for medical equipment?

No, the Masterswitch is not intended for use as a component in life-support systems or medical equipment, except with a specific written agreement from the manufacturer.
