Detailed description

SolidSwitch 104 tvrtke Victron Energy je statički prekidač namijenjen za prebacivanje istosmjernih (DC) opterećenja do 70 V/4 A. Odlikuje ga mogućnost upravljanja slabim digitalnim signalom (3,3 V < Vin < 70 V), što omogućuje fleksibilnu integraciju u različite brodovne sustave. Uređaj je kompatibilan s otpornim, kapacitivnim i induktivnim opterećenjima, poput naponskih kontaktora, s maksimalnim kapacitetima definiranim prema naponu (npr. 1000 µF do 15 V) i struji (npr. 1000 mH do 1 A).

Minimalna potrošnja za sustave s litijskim baterijama

Glavna prednost SolidSwitcha 104 je izuzetno niska potrošnja struje, oko 0,04 Ah mjesečno. Ova značajka ključna je za litijske baterijske sustave gdje je smanjenje parazitskih opterećenja esencijalno za očuvanje autonomije. Za usporedbu, mali elektromehanički relej može potrošiti između 10 i 22 Ah mjesečno, što predstavlja smanjenje potrošnje za faktor 250 u usporedbi sa SolidSwitchom 104. Ova performansa ga čini preferiranom opcijom u odnosu na tradicionalne releje za energetski osjetljive primjene.

Strateške primjene i integracija u sustav

SolidSwitch 104 idealan je za nekoliko ključnih primjena. Omogućuje upravljanje vanjskim regulatorom alternatora, poput onih tvrtki Balmar ili Mastervolt Alpha Pro, unutar litijskog sustava Victron, kao odgovor na alarm BMS-a. Također se može koristiti za prebacivanje DC opterećenja male snage, poput rasvjete, ili za povećanje broja punjača koji se mogu spojiti na izlaz ATC (allow-to-charge) BMS-a Victron. Robusna konstrukcija od crnog mat ABS-a i zaštitni stupanj IP20 osiguravaju pouzdanost u radnom okruženju od -20 do +50°C.

« Ultra-low-power DC switching for embedded systems »

The Victron Energy SolidSwitch 104 is a technically relevant solution for managing DC loads in marine and standalone installations. Its main advantage lies in its semiconductor design, enabling reliable switching of loads up to 70V/4A with negligible current consumption of just 0.04 Ah per month. This feature is critical for systems equipped with lithium batteries, where minimizing parasitic loads is essential for energy efficiency and battery longevity. Integrating this switch is particularly strategic for controlling external alternator regulators via Victron BMS signals or expanding charger management capabilities. Its ability to handle resistive, capacitive, or inductive loads makes it a versatile component. While its IP20 rating suggests installation in a protected environment, its voltage range (8-70V DC) and temperature range (-20 to +50°C) ensure adequate operational robustness for embedded applications.

Frequently Asked Questions

Need help? Contact us

What is Victron Energy's SolidSwitch 104?

Victron Energy's SolidSwitch 104 is a solid-state switch designed to switch continuous DC loads up to 70V and 4A. It is controlled by a low-power digital signal.

What is the SolidSwitch 104 primarily used for?

The SolidSwitch 104 is primarily used to control low-power DC loads, such as lighting, or to increase the number of chargers that can be connected to the ATC (allow-to-charge) output of a Victron BMS. It can also be used to control an external alternator regulator in a Victron lithium system.

What is the key difference between the SolidSwitch 104 and a traditional relay?

The main feature of the SolidSwitch 104 is its extremely low current consumption, around 0.04 Ah per month. This represents a significant reduction compared to traditional electromechanical relays, which can consume between 10 and 22 Ah per month.

What is the current consumption of the SolidSwitch 104?

The SolidSwitch 104 has a very low current consumption, around 0.04 Ah per month.

Why is the low power consumption of the SolidSwitch 104 important for lithium battery systems?

The low power consumption of the SolidSwitch 104 is critical for lithium battery systems because it significantly reduces parasitic loads. This helps preserve battery autonomy and minimizes discharge, even when the control circuit is active but the charger or alternator is not charging.

Is the SolidSwitch 104 a mechanical or static switch?

The SolidSwitch 104 is a static switch.

What material is the SolidSwitch 104 housing made of?

The SolidSwitch 104 housing is made of matte black ABS.

What are the dimensions of the SolidSwitch 104?

What is the ingress protection (IP) rating of the SolidSwitch 104?

The SolidSwitch 104 has an IP20 ingress protection rating.

What is the operating temperature range of the SolidSwitch 104?

The SolidSwitch 104 operates within a temperature range of -20 to +50°C.

What input voltages are accepted by the SolidSwitch 104?

The SolidSwitch 104 accepts an operating input voltage (Vbat) between 8 and 70V DC.

What types of loads can the SolidSwitch 104 switch?

The SolidSwitch 104 can switch DC resistive, capacitive, or inductive loads, such as the coil of a power contactor.

What is the maximum current load that the SolidSwitch 104 can handle?

The SolidSwitch 104 can handle a maximum charging current of 4A.

What is the maximum capacitive load supported by the SolidSwitch 104?

Up to 15V: 1000 µFBetween 15V and 30V: 400 µFBetween 30V and 70V: 50 µF

What is the maximum inductive load capacity supported by the SolidSwitch 104?

Up to 1A: 1000 mHBetween 1A and 2A: 100 mHOver 2A: 10 mH

Can the SolidSwitch 104 be used to control an external alternator regulator?

Yes, the SolidSwitch 104 is designed to control an external alternator regulator, such as those from Balmar or Mastervolt Alpha Pro, within a Victron lithium system, typically in response to a BMS alarm.

Is the SolidSwitch 104 compatible with Victron BMS to increase ATC outputs?

Yes, the SolidSwitch 104 can be used to increase the number of chargers that can be connected to the ATC (allow-to-charge) output of a Victron BMS.

How is the SolidSwitch 104 controlled?

The SolidSwitch 104 is controlled by a low-power digital signal via its remote input (Vin).

What is the input voltage range (Vin) for the remote signal to activate the load?

To activate the load, the remote input voltage (Vin) must be between 3.3V and 70V. If Vin is floating or below 3V, the load is disabled. The minimum input current for activation is 30 µA.

Is the SolidSwitch 104 protected against reverse polarity or short circuits?

No, the SolidSwitch 104 is not protected against reverse polarity and is not protected against short circuits. It is essential to respect the polarities during installation and to provide external protections if necessary.
