Connex SMPS300RS Switching Power Supply Module 300W 36V

Module d'alimentation à découpage Connex SMPS300RS

The Connex SMPS300RS is a half-bridge resonant switched-mode power supply (SMPS) capable of delivering 300W continuous and up to 360W peak. It is configured for a 36V output voltage and also features an unregulated differential output of approx. ±18V at a maximum current of 500mA. The main output voltage is regulated and adjustable within a range of approx. 10% ±5%).

The main feature of this power supply is the absence of heat sinks for the power MOSFETs and rectifier diodes, due to the increased efficiency, up to 92%. What's more, the amount of EMI interference is much lower than that of any conventional power supply, and could be compared to a regulated linear power supply. Footprint and weight are also considerably reduced, enabling the SMPS300RS to be installed in a compact case. The SMPS300RS also features overcurrent protection that limits output current to around 110% to 120% of maximum power.

As the main output voltage of this power supply is regulated, it is suitable for Class AB and Class D/T amplifiers with a medium PSRR value. Target applications for this power supply module are Class D BTL output amplifiers.

Connex SMPS 300RE 36V
Cette alimentation est utilisée avec une amplificateur Fosi BT20A Pro en replacement de la 32V/5A d’origine.
Pas de différence notable à l’écoute, peut être un rendu poil plus douce dans le médium aigu.
Concerant le bruit de fond impossible de dire si elle fait mieux ou moins bien que celle d’origine, sur des pavillons midbass + compression de 105db/w, le souffle dans l’aigu est toujours présent même si plus lissé, le léger tiktiktiktik du hachage également, les deux étant donc définitivement imputables à l’ampli qui ne bat pas des records de rapport de recul de bruit de fond.

Cette alim ne mesure que 30mm de haut au lieu des 40mm annoncés, un boitier Galaxy 40 plutôt qu’un Galaxy 80 aurait pu suffire, au moins elle respire et reste totalement froide.

Bonne alim
Je l'utilise pour alimenter 2 amplis classe D TPA3251 connectés à 2 enceintes 2 vois actives. Tres silencieuse, mais je ne peux pas dire si avec une alim plus bas de gamme ca serait moins bien ...
Attention: la doc de l'alim décrit la version 2x36V (+36 / 0V / -36), ajustables avec un potentiomètre. La version que j'ai reçue est 1 sortie +36V fixe. Ce qui me suffit.

Très bonne alimentation, stable, fiable, les mesures multimètre sont au RDV. Excellent ripple et clairement orienté pour les amplis Audiophiles. LLC + Softstart

Bonne alimentation SMPS
Alimentation utilisée pour un amplificateur audio de 2x150W à base de puces classe D. Même si je ne l'ai pas chargée complètement a fond, je vois qu'elle ne chauffe pas, qu'elle est silencieuse. Encombrement compacte. Rien à redire.
