Detailed description

Mastervolt Masterswitch 25 kW 230 V dėžė yra jūsų laivo nuolatinės srovės įrenginio širdis. Sukurta pakeisti rankinį jungimą tarp dviejų kintamosios srovės šaltinių, šis automatinis perjungimo įtaisas valdo iki 25 kW galią su 125 A maksimaliu srovės stipriu tiek įėjime, tiek išėjime. Skirtingai nuo bazinių perjungimo įtaisų, šis pramoninis modelis užtikrina sklandų perėjimą tarp dyzelinio generatoriaus, prieplaukos lizdo ar keitiklio su itin greitu perjungimo laiku (12–22 ms įjungiant, 4–19 ms išjungiant).

Išmanioji prioritetų tvarkymo ir sistemos apsauga

Masterswitch 25 kW turi dvi kintamosios srovės įėjimo ir vieną išėjimo kryptį. Įėjimas 1 turi absoliutų prioritetą, idealų dyzelinių generatorių ar prieplaukos lizdų jungimui. Kad apsaugoti generatoriaus mechaniką ir laivo tinklą nuo įtampos bei dažnio svyravimų, reguliuojamas 0–10 sekundžių įsijungimo delsos laikas (pagal nutylėjimą nustatytas į 10 sekundžių), leidžiantis generatoriaus stabilizacijai prieš apkrovos priėmimą. Įėjimas 2, kuris yra antros eilės prioritetas, automatiškai perima, kai nėra įtampos prioritetiniame įėjime, nenaudojant jokios energijos (0 W), kai naudojamas vienas su keitikliu. Esant maksimaliam apkrovimui visais įėjimais, dėžės vidinė energijos suvartojimas lieka minimaliu – 26 W.

Robusti dizainas jūrinėms sąlygoms

Atitinka IP55 apsaugos standartą, ši 3,8 kg dėžė (matmenys 291 x 241 x 168 mm) skirta atlaikyti drėgnas aplinkas ir ekstremalias temperatūras (nuo -5 °C iki 60 °C veikimo metu). Įrengimas palengvinamas naudojant galingus gnybtus, priimančius laidus nuo 4 iki 50 mm² skerspjūvio (AWG 10 iki 1/0). Nors šis modelis nėra suderinamas su MasterBus tinklu ir neturi įmontuotų saugiklių (skirtingai nei Masterswitch Fuses versija), jo grynai elektromechaninė konstrukcija užtikrina absoliučią patikimumą laivams, reikalaujantiems sunkaus ir saugaus energijos valdymo.

Expert review

Skaitmeninės veiklos vadovas

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

The Masterswitch 25 kW unit stands out as a key component for managing high power loads aboard 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 vessel. Although it lacks a MasterBus interface, this simplicity ensures immunity to communication failures. With oversized terminals accepting cables up to 50 mm² and an IP55 enclosure, this is a high-quality industrial-grade device 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 box 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, with no manual intervention required.

What is the maximum power and current supported?

This industrial transfer switch can handle high power levels 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 installation.

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 (set by default to 10 seconds) allows the generator to start up and stabilize its voltage and frequency before taking the load, which protects 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 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 during the switch-over?

Yes, due to the micro-cut 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.

Should external fuses or circuit breakers be provided?

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 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 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 minimalist and industrial style: it has no LED indicators on the unit nor any port for remote control.

Where should I install the transfer switch on board?

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

Can this switch be used for medical equipment?

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