16.Damage Requiring Service

Unplug this product from the wall outlet and refer servicing to qualified service personnel under the following conditions:

a)When the power-supply cord or plug is damaged.

b)If liquid has been spilled, or objects have fallen into the product.

c)If the product has been exposed to rain or water.

d)If the product does not operate normally by following the operating instructions. Adjust only those controls that are covered by the operating instructions as an improper adjustment of other controls may result in damage and will often require extensive work by a qualified technician to restore the product to its normal operation.

e)If the product has been dropped or damaged in any way.

f)When the product exhibits a distinct change in performance – this indicates a need for service.

17.If glass components, including lens and lamp, should break, contact your dealer for repair service.

This product incorporates glass components, including a lens and a lamp. If such parts should break, please handle with care to avoid injury and contact your dealer for repair service. The broken pieces of glass may cause to injury.

In the unlikely event of the lamp rupturing, thoroughly clean the area around the projector and discard any edible items placed in that area.

18.Servicing

Do not attempt to service this product yourself as opening or removing covers may expose you to dangerous voltage or other hazards. Refer all servicing to qualified service personnel.

19.Replacement Parts

When replacement parts are required, be sure the service technician has used replacement parts specified by the manufacturer or have the same characteristics as the original part. Unauthorized substitutions may result in fire, electric shock, or other hazards. (Replacement of the lamp only should be made by users.)

20.Safety Check

Upon completion of any service or repairs to this product, ask the service technician to perform safety checks to determine that the product is in proper operating condition.

TLP381, TLP380 specifications

The Toshiba TLP380 and TLP381 are advanced optoisolators designed for various applications requiring reliable isolation and switching control. These devices are particularly valuable in communication, industrial, and consumer electronics, where signal integrity and noise immunity are crucial.

The TLP380 is a phototransistor optoisolator, featuring a gallium arsenide infrared LED and a phototransistor. With a minimum isolation voltage of 5,000 VRMS, it provides high voltage isolation between input and output, making it an excellent choice for protecting sensitive components from high voltages and surges. The TLP380 offers a high-speed switching capability, with a rise time of around 4 μs, enabling it to transmit signals efficiently in digital circuits.

On the other hand, the TLP381 is also a phototransistor optoisolator but specifically optimized for lower input current, making it more power-efficient. It offers similar isolation voltage ratings and switching characteristics to the TLP380, but with a lower input current threshold, which can be particularly advantageous in battery-powered applications. The lower current requirement helps extend battery life and minimizes power consumption in portable devices.

Both TLP380 and TLP381 devices feature a wide temperature range, making them suitable for various environmental conditions. Their operating temperature ranges from -40°C to +100°C, ensuring reliable performance under extreme conditions. Additionally, with their compact DIP packages, they are easy to integrate into crowded PCB layouts, making them a preferred choice for designers targeting space-constrained applications.

In terms of characteristics, both models provide low output voltage saturation and high-speed operation, which are critical in achieving fast response times in control circuits. The combination of robust isolation, efficient power consumption, and temperature stability makes the TLP380 and TLP381 versatile solutions for isolating signals in a myriad of electronic systems.

In summary, the Toshiba TLP380 and TLP381 optoisolators are engineered for high-performance signal isolation, offering superior technologies and characteristics that cater to a range of applications. Their reliability, efficiency, and compact design make them a compelling choice for engineers and designers looking to enhance their electronic systems.
