Why Jensen Heavy Duty & Marine?

Hi/Low Temperature

Jensen products are exposed to a Long-Duration of high and low temperature extremes and rapid temperature cycles that are experienced in outdoor mobile applications.

Extreme temperatures are the leading cause of failures in most types of equipment. Not only while operating, but also while stored in a non-operational state.

Consequently, Jensen subjects their equipment to high and low temperature extremes while operational, as well as while non-operational, thus ensuring your JENSEN product will perform even after prolonged periods of storage with no power in extreme hot or cold temperatures.

Because humidity is introduced at higher temperatures, Jensen does a high humidity test to check the effectiveness of the conformal coating, which protects the electronic circuits against moisture, corrosion, dust, chemicals, and temperature extremes.

 Rapid temperature cycles Tests the superior ability of parts to resist extremely low and high temperatures, as well as their ability to withstand cyclical exposures to these temperature extremes. Used to ensure powered components withstand temperature fluctuations.

Shorted I/O

If you are like me, you have at one time or another stuck a connector that was supposed to go into an input, into an output and blasted one of, or both of your components.

 Good manufacturers like Jensen know this and have designed their equipment to stand the pain.

Output short circuit current tests simulate what would be a worst-case scenario, so that you can rest assured, that should you accidentally do this with your Jensen equipment, all is not lost. Once you reconnect the equipment properly, your Jensen components will work they way they were designed to work. And for you.. Money saved.

Temperature/Vibration Chamber

Real world mobile products are exposed to a wide variation of temperature and vibration changes. Truckers travel from cold to hot climates and back and hit roads from smooth highways to bumpy dirt roads.

To simulate rugged road conditions, Jensen exposes products to Long-Duration simulations of temperature changes and operational vibration. In addition simultaneous temperature cycle and vibration test are also conducted to collect data, relevant to detecting potential product weaknesses and for calculating product life-expectancy.

Power Line Noise Rejection

Power-line Noise is a spark or arcing across some power-line related hardware. It has a characteristic sound that is often described as a harsh and raspy hum or buzz and the this can sound pretty much the same to the human ear. This Test throws noise onto the signal and simulates product reaction to alternator whine.

UV/Salt Fog Corrosive Exposure Chamber

Exterior components are subjected to accelerated UV exposure that equates to 5-7 years of actual outdoor exposure to assure you that your electronics will look great for many years. In addition, product and product components are subjected to dry/wet cycles of highly corrosive fog/mist to test for corrosion resistance and corrosion protection effectiveness.

High/Low Operating Voltage Test

Equipment has to stand up to a certain voltage without damage under operating conditions. Both high and Low Voltage tests are used to ensure consistency when vehicle battery goes below or above the normal 12V. Changes in Voltage will produce changes in Current (Ohms law, E = IR), which can damage lower quality electronics. Voltage applied is about twice the normal voltage and product must remain operational throughout the test.

Safety precautions are taken so as to ensure that there is no access to the testing area when the high voltage is on.

Simulated Crank Start Voltage

A Simulated Crank Start Voltage test is used to make sure your Jensen product will hold up, even when vehicle is turned on.
