Detailed description

El SolidSwitch 104 de Victron Energy és un commutador estàtic dissenyat per a commutacions de càrregues en corrent continu (DC) fins a 70V/4A. Es distingeix per la seva capacitat de ser controlat mitjançant un senyal digital de baixa potència (3,3V < Vin < 70V), oferint flexibilitat d’integració en diversos sistemes embarcats. Aquest dispositiu és compatible amb càrregues resistives, capacitives o inductives, com ara bobines de contactors de potència, amb capacitats màximes especificades segons la tensió (per exemple, 1000 µF fins a 15V) i el corrent (per exemple, 1000 mH fins a 1A).

Consum parasitari mínim per a sistemes de liti

L’avantatge principal del SolidSwitch 104 rau en el seu consum de corrent extremadament baix, d’uns 0,04 Ah al mes. Aquesta característica és crucial per als sistemes amb bateries de liti, on la reducció de càrregues paràsites és essencial per preservar l’autonomia. A tall de comparació, un petit relé electromecànic pot consumir entre 10 i 22 Ah al mes, cosa que representa una reducció de consum per un factor de 250 amb el SolidSwitch 104. Aquest rendiment el posiciona com a solució preferent respecte als relés tradicionals en aplicacions sensibles al consum energètic.

Aplicacions estratègiques i integració en sistemes

El SolidSwitch 104 és ideal per a diverses aplicacions clau. Permet controlar un regulador d’alternador extern, com els de Balmar o Mastervolt Alpha Pro, dins d’un sistema de liti Victron, en resposta a una alarma del BMS. També pot servir per a commutacions de càrregues DC de baixa potència, com ara enllumenat, o per augmentar el nombre de carregadors que es poden connectar a la sortida ATC (allow-to-charge) d’un BMS Victron. La seva construcció robusta en ABS negre mat i el seu grau de protecció IP20 garanteixen una fiabilitat en un entorn d’explotació de -20 a +50°C.

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

The Victron Energy SolidSwitch 104 is a technically sound solution for managing DC loads in marine and standalone installations. Its main advantage lies in its semiconductor-based 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 for 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 operating temperature (-20 to +50°C) ensure adequate operational robustness for embedded applications.
