Detailed description

Mastervolt Masterswitch 25 kW 230 V kassettinn er stjórnunarmiðstöð rafkerfisins á borðinu þitt. Hönnunin er til að koma í stað handvirkrar skiptingar milli tveggja riðstraums (AC) raforkugjafa. Þessi sjálfvirkur skiptibox sér um afl upp að 25 kW með hámarksstraum 125 A á bæði inntak og úttak. A.m.k. skiptibox eru einfaldlega skiptibox en þetta iðnaðarstig tryggir óslitin skiptingu milli raforkugjafa, landspennu eða umbreytara með mjög hraðri skiptitíma (12 til 22 ms við upphaf og 4 til 19 ms við brotttöku).

Greind stjórnunarforgangs og kerfisvernd

Masterswitch 25 kW hefur tvö AC inntök og eitt úttak. Inntak 1 hefur algjöran forgang og er ætlað fyrir raforkugjafa eða landspennu. Til að vernda raforkugjafa fyrir spennu- og tíðni sveiflum og vernda rafkerfið um borð er stillanlegur tími fyrir skiptingu upp á 0 til 10 sekúndur (sjálfgefið 10 sekúndur) til að raforkugjafinn geti stabilizerað sig áður en hann tekur við aflinu. Inntak 2, sem hefur annars flokks forgang, tekur við sjálfkrafa ef spenna er ekki til staðar á forgangsinntaki án þess að neyta orku (0 W) ef það er notað einungis með umbreytara. Við hámarksálag á öllum inntökum er innri orkunotkun kassettans aðeins 26 W.

Hönnun fyrir stranga sjávarumhverfi

Í samræmi við IP55 staðal er þessi 3,8 kg kassett (mál 291 x 241 x 168 mm) hannaður til að þola raka og öfgakenndar hitastig (frá -5 °C upp í 60 °C í notkun). Uppsetning er einföld með skrunaborðum sem taka við þykkum vírum frá 4 til 50 mm² (AWG 10 til 1/0). Þótt það sé ekki samhæft MasterBus neti né hafi innbyggða raflosa (ólíkt Masterswitch Fuses útgáfunni) er einfaldur rafmekanískur hönnun kassettans trygging fyrir fullkomna áreiðanleika fyrir skip sem þurfa örugga og þungar aflstjórnunarkerfi.

Stjórnandi stafrænna hluta

« The reference for high-power automatic switching for 230 V networks »

The Masterswitch 25 kW unit is a key component for managing high power loads on large vessels. Its ability to handle 125 A continuously on a 230 V network makes it suitable for heavy-duty installations where reliable AC switching is critical. I particularly appreciate the adjustable mechanical delay of up to 10 seconds on the priority input: this is an essential protection feature to allow a generator time to stabilize its frequency before powering the onboard systems. Although it lacks a MasterBus interface, this simplicity ensures immunity to communication failures. With its oversized terminals accepting cables up to 50 mm² and its IP55 housing, this is an industrial-grade piece of equipment designed to last the lifetime of the vessel, provided it is properly protected by appropriate upstream differential circuit breakers.

Frequently asked questions

Need help? Contact us

What is the Masterswitch 25 kW unit used for?

It automatically switches between two alternating current sources (such as a generator and a shore power connection) to power the onboard electrical system without any manual intervention.

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 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 the priority between the two inputs work?

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

Why is there a switching delay on the main input?

A switching delay (default set to 10 seconds) allows the generator to start and stabilize its voltage and frequency before taking the load, protecting your onboard electrical system.

Is it possible to adjust 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 warm-up time), it is recommended to set this delay to 0 seconds.

What is the switching time between the two power sources?

The transfer time is ultra-fast: expect 12 to 22 milliseconds when powering on, and 4 to 19 milliseconds when powering off.

Do computers risk shutting down when switching power sources?

Yes, due to the micro-interruption 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, providing effective protection 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 unit 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 carried out?

The grounding terminal of the Masterswitch 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 230 V single-phase systems (with an input range of 200 to 250 V), operating at a frequency of 50 or 60 Hz.

Does the housing have LED indicators or a remote control?

No, this model is designed to be sleek and industrial: it has no LED indicators on the housing nor a connection port for a remote control.

Where should I install the transfer switch aboard?

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 electrical shock.

Can this switch be used for medical equipment?

No, the Masterswitch is not intended to be used as a component in life-support systems or medical equipment, unless a specific written agreement is obtained from the manufacturer.
