SOGLIA

LIN/QUAD (JP9):

jumper to set the out- put voltage in LIN- EAR or QUADRATIC mode.

LINEAR: for each voltage command signal variation corre- sponds, in propor- tional mode, a varia- tion of the output volt- age.

QUADRATIC: allows to obtain soft start of the load. Practically, small fan speed varia-

tions for bigger volt- 10Vdc age command signal

variations are ob- tained at lower values

per rilevanti variazioni della tensione di comando a valori bassi del segnale (tra 0 e 4Vdc).

Viceversa si ottengono rilevanti variazioni di velocità del ventilatore per piccole variazioni della tensione di co- mando a valori alti del segnale (tra 7 e 10Vdc). Ciò offre risposte più rapide all'avvicinarsi al limite superiore della tensione di comando.

10V/∝CH (JP7): definisce la tipologia del segnale di co- mando. Set impostato a 10V - non modificare.

INPUT (JP5): non utilizzato

CUT-OFF/MIN (JP8): definisce il comportamento del rego- latore quando la tensione di comando scende ad 1Vdc.

-CUT-OFF: il regolatore interrompe l'erogazione della tensione di uscita e non alimenta più il carico.

-MIN: il regolatore imposta la tensione di uscita al valore MIN (set di fabbrica 80V).

50Hz/60Hz (JP13): definisce la frequenza di alimentazione.

I/V (JP6): non utilizzato

(from 0 to 4Vdc).

Viceversa, bigger fan speed variations for small voltage command signal variations are obtained at higher values (from 7 to 10Vdc).

This allows faster reaction of the device when the voltage command signal is at higher values.

10V/∝CH (JP7): fixes the voltage command signal type. It is factory setted to 10V - do not modify.

INPUT (JP5): Not used

CUT-OFF/MIN (JP8): fixes the working mode of the device when the voltage command signal drops to 1Vdc.

-CUT-OFF: the device cut-off the output voltage and does not feed the load.

-MIN: the device automatically set the output voltage to MIN value (factory setted to 80V).

50Hz/60Hz (JP13): fixes the power supply frequency.

I/V (JP6): Not used

MP2000 specifications

The Dell MP2000 is a versatile multimedia projector designed to deliver impressive performance for both business and entertainment purposes. This projector offers a sleek design and robust features, making it an ideal choice for presentations, classroom environments, and home theater setups.

One of the standout features of the Dell MP2000 is its high brightness capability. With a brightness rating of about 3,000 ANSI lumens, it ensures clear and vivid projections even in well-lit environments. This brightness level makes it suitable for various settings, from large conference rooms to small classrooms, ensuring that the content is easily visible to all audiences.

In addition to its brightness, the MP2000 boasts a native resolution of XGA (1024x768 pixels), providing sharp and detailed images. The projector supports a range of resolutions up to UXGA (1600x1200), ensuring compatibility with various media formats. This versatility allows users to project high-quality videos, presentations, and images with excellent clarity.

The MP2000 employs DLP (Digital Light Processing) technology, which enhances image quality and color accuracy. DLP is known for its superior brightness and contrast characteristics, giving presentations a professional look. The projector’s color wheel ensures vibrant colors, making it perfect for showcasing graphics and videos.

Connectivity options on the Dell MP2000 are extensive, catering to various devices and media sources. It includes multiple input ports, such as VGA, HDMI, and USB, allowing easy connection to laptops, desktops, and other devices. The inclusion of an RS-232 port also enables integration into larger AV systems for more streamlined control.

Portability is another key characteristic of the MP2000. Weighing less than 5 pounds, it is easy to transport, making it a great option for traveling professionals or educators who need to move between locations. The projector also features an intuitive interface and remote control, facilitating user-friendly navigation through menus and settings.

For added convenience, the MP2000 supports rapid startup and shutdown processes, reducing waiting times between presentations. Its lamp life is impressive, lasting up to 5,000 hours in eco mode, which minimizes maintenance costs and ensures longevity.

In conclusion, the Dell MP2000 is a powerful and reliable projector that excels in brightness, image quality, and connectivity. Its DLP technology, portability, and user-friendly features make it a top choice for anyone looking to enhance their presentation or home viewing experience. Whether for educational purposes or business meetings, the MP2000 delivers outstanding performance and versatility.
