and one-phase DC 12V output. It can meet the common DC load within 12V 1800W and it is
especially suitable for the conditions where the PSU demands are stricter, for example, servers and
mining machines. Properties are as follows：
100-140V /200-240V Wide voltage input, power factor is > 0.99 (fully loaded)
Up to 95% efficiency (excluding output current leakage)
Output ripple <1%.
Under-voltage, short circuit, over-power and overheat protection with automatic fault detection and
recovery, automatic recovery after fault removal.
High quality components are selected to ensure the stability and reliability of the PSU and ensure that
it can work at fully loaded status in high temperature environments up to 60 degrees Celsius.
Small size and high power density.

Precautions for Use：
1. Before using the PSU, please ensure that your local voltage and power outlets are compatible with the
requirements of the product. Output voltage from the power socket should meet the product’s voltage
requirement. The leading‐out terminal model, polarity and quantity must also be in accordance with the product
requirements stipulated in this guide.
2. Please ensure that the PSU appears to be in good shape and has not suffered any damage in transit. If the exterior
of the PSU appears damaged, do not use it.
3. Make sure that the ground electrode of PSU is properly grounded to ensure the electricity safety and EMI
reduction.
4. As different countries have different power outputs, we do not supply an AC input cable with our PSUs.
Customers should purchase an AC input cable output that is compatible with the local power grid plug. The type
number of the cable end interface to be connected with the power panel is C13, and the sectional area of copper
conductor for cables should not be less than 1 square millimeter.
5. The PSU must be installed in an dust-free environment with good and unobstructed air circulation. Any items
blocking the air flow of the PSU is prohibited and under no circumstances should the PSU be installed in an
enclosed place. Installation also should not be done in environment where there is high condensation or high level
of salt content and humidity in the air.
6. The correct way to use the PSU is to connect the output wire terminal, and then connect the input cable after the
load and PSU output terminals are connected. Either connecting or disconnecting the output terminals are forbidden
when the PSU is powered on. Voltaic arcs generated by excessive DC can damage DC output terminals and pose a
fire hazard.
7. Maintaining a good working environment and derating can greatly prolong the lifespan of PSU. It is generally
recommended that the load power not exceed 90% of the rated power of the PSU and the temperature not exceed
50 degrees Celsius. It should be used in a dust-free, non-polluted area where there is low humidity and low salt
content in the air. The derating method will also allow the PSU to work at a higher efficiency point, which can help
in electricity savings.

Précautions d’utilisation:
1.Avant d’acheter l’alimentation, confirmez d’abord que la tension du réseau local répond aux
exigences de l’alimentation locale, que la tension de sortie de l’alimentation et les spécifications de
puissance peuvent répondre aux exigences des produits de charge, que le modèle de borne de sortie
de l’alimentation, les polarités et la quantité sont conformes aux exigences de la charge.
2. Après avoir ouvert l’emballage d’alimentation, confirmez que l’apparence de l’alimentation est
normale, sinon, il est interdit de mettre sous tension pour l’utilisation.
3.Le fil de mise à terre de l’alimentation électrique doit être mis à la terre de manière fiable pour
assurer la sécurité de l’utilisation et réduire les interférences électromagnétiques.
4.En tenant compte des différences concernant les normes des prises d’alimentation dans différents
pays, l’alimentation standard n’est pas équipée d’un câble d’entrée AC. Veuillez acheter le câble
d’entrée AC compatible avec la prise du réseau électrique local vous-même. Le type d’interface du
câble apparié au panneau d’alimentation est C13, la section du conducteur en cuivre de câble ne doit
pas être inférieure à 1mm².
5.Il faut installer l’alimentation dans un endroit avec bonne circulation d’air mais sans poussière. Il
est interdit d’affecter la buse d’alimentation à cause des objets étrangers ou d’installer l’alimentation
dans un espace confiné. Il est interdit d’installer cette alimentation dans un environnement où il
existe le brouillard salin et la condensation.
6.Pour l’installation normale d’alimentation, il faut connecter d’abord la borne de sortie, et après la
connexion correcte entre la charge et la borne de sortie de l’alimentation, connectez le câble d’entrée
CA. Il est interdit de connecter et déconnecter la borne de sortie lors de la mise sous tension. L’arc
électrique généré par un courant CC CA trop grand endommagerait la borne de sortie CC, voire
provoquera un risque d’incendie.
7.Il faut garder un bon environnement de travail et le déclassement pour prolonger considérablement
la durée de vie de l’alimentation. Généralement, il est recommandé que la puissance de charge ne
dépasse pas 90% de la puissance nominale de l’alimentation, qu’elle est utilisée dans un
environnement inférieur à 50℃, sans poussière, sans acide-alcali ou pulvérisation de sel. Le
déclassement peut également assurer le travail de l’alimentation plus efficacement pour économiser
une partie de frais d’électricité.
