Press ON/STANDBY after using the projector.

An instruction message for turning the power off appears on the screen and disappears after a while. When the message disappears, operation becomes invalid.

Press ON/STANDBY again.

Cooling starts. Once cooling is completed, the LAMP and FAN indicators turn off and the standby mode is set. (The ON indicator turns in orange.)

ATo protect the light source lamp, the LAMP indicator blinks as long as a minimum of cooling is necessary. The power cannot be turned back on during this time. Unplugging the power cord at this time will shorten the lamp’s duration life.

BThe cooling fan continues to run for a while to expel the heat remaining inside. If you are in a hurry, however, you may unplug the power cord at this time.

CThe standby mode is set.

Notes

The projector consumes about 15W of power in the standby mode. We recommend you unplug the power cord when not using the projector for long periods of time.

Be sure that the LAMP indicator has turned off before unplugging the power cord. Cutting the power by unplugging the power cord while the projector is operating or the light source lamp is being cooled will shorten the lamp’s duration life. Should a fault or some other irregularity arise with this unit, unplug the power cord.

When reinserting the power plug before the lamp has cooled, please wait until the lamp has cooled sufficiently before use. When the lamp is at a high temperature, it may not light and it’s life duration will be shortened.

These optoisolators are designed to provide exceptional performance in various applications, including industrial controls, communication equipment, and power supplies.

The TLP250 is a high-speed transistor optoisolator that boasts a maximum data transmission rate of up to 10 Mbps. It is designed for applications where precise isolation between input and output is critical. The device employs a GaAlAs light-emitting diode, ensuring a fast response time and efficient operation. Its package includes a phototransistor, which enables it to switch high voltages and currents, making it ideal for driving loads in various circuits.

In contrast, the TLP551 offers a higher level of phototransistor isolation with a breakdown voltage of up to 5 kV. This model is well-suited for environments where electrical noise is a concern, as it provides reliable and stable isolation. With a maximum forward current of 50 mA, the TLP551 ensures that even in complex industrial settings, signal integrity can be maintained effectively.

The TLP550 is another noteworthy optoisolator, characterized by its compact size and robust performance. It also integrates a phototransistor output, which allows for a high degree of flexibility in design. This model is engineered to deliver a maximum isolation voltage of 3.75 kV, making it suitable for various high-voltage applications.

Finally, the TLP251 offers a unique combination of features tailored for demanding applications. With its high-speed response and excellent voltage gain, it is particularly advantageous in communication systems. Its ability to provide isolation while transferring data makes it an essential component for many digital interfaces.

In summary, the Toshiba TLP series, including models like the TLP250, TLP551, TLP550, and TLP251, exemplify the brand's commitment to quality and innovation in optoelectronic devices. These models are engineered to meet the rigorous demands of modern applications, offering features such as high-speed operation, significant isolation voltage ratings, and versatile output options. For engineers and designers, choosing the right Toshiba optoisolator can significantly enhance the reliability and efficiency of their electronic systems.
