![The image features a red triangular warning sign containing a white exclamation point in its center. Below the triangle is the word 'WARNING:' printed in black, uppercase letters.](.mxa-312m-50m-44a02-1000-10/c405b6cc88cb9552dccf36e73dba834b99b21dafde021b213f26bd0e54282345.jpg)

Please use an approved power source as certified by IEC or UL.

If you need adaptor, optional accessories or further assistance, please contact with ADLINK for further information.

The altitude during operation is up to 5000 m whose output meets LPS and SELV (ES1) circuits.

The output rating of DC power source as following:

Voltage: 12 VDC
• Current: 3.65A

Before providing DC power to the apparatus, ensure the voltage and polarity provided are compatible with the DC input. Improper input voltage and/or polarity can be responsible for system damage.

Veuillez utiliser une source d'alimentation approuvée et certifiée par IEC ou UL. Si vous avez besoin d'un adaptateur d'appareil, d'accessoires en option ou d'une assistance supplémentaire, veuillez contacter ADLINK pour plus d'informations.

L'altitude pendant le fonctionnement est jusqu'à 5000 m dont la sortie répond aux circuits LPS et SELV (ES1).

La puissance nominale de sortie de la source d'alimentation CC comme suit

Tension : 12 VDC

Courant : 3.65A

Avant de fournir une alimentation CC à l'appareil, assurez-vous que la tension et la polarité fournies sont compatibles avec l'entrée CC. Une tension et/ou une polarité incorrectes peuvent causer des dommages irréversibles sur le système.
