Unité de détection de puissance de haute précision CUAV CAN PMU | Pour drone et contrôleur de vol
CAN PMU
Unité de détection de puissance de haute précision
Précision de mesure de 0,05 V 0,1 A Tension de sortie stable 5V/5A Prise en charge maximale d'une tension d'entrée de 62 V Détection de courant max 110A
Description du produit
CAN PMU est une unité de gestion de l'alimentation du drone avec un processeur STM32F4 intégré et exécutant l'algorithme CUAV ITT. Il peut mesurer avec précision la tension et le courant du drone en temps réel. Il prend en charge une tension maximale de 6 à 62 V et un courant de 110 A et peut produire 5,4 V 5 A. (Maximum instantané 8 A / 120 s, constant 5 A) Alimente le contrôleur de vol, utilise la communication par bus CAN, prend en charge le protocole CAN UAV standard et chaque unité PMU est calibrée en usine pour garantir une bonne cohérence et une grande précision.
Algorithme ITT auto-développé pour faciliter la mesure de haute précision
CAN PMU utilise l'algorithme de suivi de la température d'impédance ITT développé en interne pour compenser les erreurs de mesure causées par les changements d'impédance à différentes températures de fonctionnement, permettant à CAN PMU de maintenir des mesures de tension et de courant de haute précision cohérentes à différentes températures de fonctionnement.
Communication numérique, sûre et fiable
Le CAN PMU adopte le protocole de communication numérique standard UAVCAN. Toutes les informations sont transmises numériquement pour éviter les problèmes d'erreur causés par les ADC traditionnels qui sont facilement sensibles à l'atténuation et aux interférences.
Estimations précises de la consommation d'énergie
En interne, grâce à un échantillonnage en temps réel de plus de 100 Hz et à des statistiques en temps réel de consommation d'énergie / consommation d'énergie instantanée, transmettez des informations précises sur la consommation d'énergie au contrôleur de vol pour obtenir un vol plus sûr et plus contrôlable
Faible EMI, sortie régulée à courant élevé de 5 A
Le régulateur de tension intégré utilise la puce LT8645S, prend en charge l'entrée 62 V, le régulateur de tension abaisseur synchrone 5,4 V / 5 A *, a des EMI et EMC ultra-faibles, une efficacité de conversion jusqu'à 95%, répond aux périphériques de contrôle de vol des drones de l'industrie et aux besoins d'application importants en matière de consommation d'énergie.
