Why Jensen Heavy Duty & Marine?

Jensen keeps working long after others bite the dust!


Jensen Heavy Duty & Marine products are specifically designed and tested to withstand real world applications like Trucking and of course boating. That means the Jensen TVs and other equipment are built to withstand harsh environments, such as moisture, salt air, humidity, UV exposure, and extreme temperatures. Jensen's Research and Development team builds each product from the ground up, incorporating the latest technologies and finally running them through a battery of test to ensure the Jensen product line is at the front of the pack.

Jensen makes sure that their products perform well by running them thorough a multitude of stringent validation tests, that ensure every unit is ready for both heavy Duty and Marine use. Jensen products are also developed with exclusive marine features, that will assure the end user, years of high quality, dependable entertainment.

Some of the exclusive engineering tests that Jensen performs on their products include the following:

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.

RF Performance Testing

Since many TV owners live in areas that have marginal coverage, and many use a less expensive low-gain antenna, good RF performance is an absolute must for an enjoyable user experience.

Jensen's  RF Performance test ensures that the Jensen product line, all keep clean signals in and the bad signals out, so that users are left with a steady signal without outside interference.

Jensen not only test for high level RF performance during product design, but they also take random samplings from each production lot and test them to ensure performance consistency. Jensen performs over 80 performance tests, that are conducted to analyze and validate RF and audio performance.

Electrostatic Discharge

The last thing you need is for your radio to quit due to accidental static shock. That's why our products go through the extensive Electrostatic Discharge Test on all exposed control areas as well as I/O connections so they can withstand the most severe static build up. Shocking, isn't it?

Reverse Polarity

Accidents can occur anytime and certain appliances are no exception. If the wires of an outlet are reversed, there is the possibility that the electrical current may damage appliances and electrical motors. The Reverse Polarity test uses a car battery to test durability of the product when the (+) and (−) cables are accidentally reversed.

Load Dump

Jensen understands what it takes to protect electronics that are exposed to different electrical environments. That's why all Jensen products include significant front-end circuit protection and filtering that has been proven to withstand the toughest electrical environments. The Load Dump Tests puts destructive pulses (spikes) to simulate the sudden disconnection of the battery from the alternator while the alternator is generating current to load the battery. These Load Dump high energy pulses have a high potential for destruction ensuring that your Jensen electronics are protected.

Inductive Load Switching

A careful balance is calculated so that too much inductance is not added. Switching capacitance directly will damage contacts rapidly with high inrush currents. Inductors initially impede the flow of current, thereby reducing inrush currents. Jensen Tests their products well above, as well as below the average waveform to ensure that they can withstand extreme fluctuations.

High-Pressure Spray

Jensen externally mounted products are tested with high pressure water by blasting the product with 13,000 lbs. of water pressure as close as 6 inches to the product. This will test the resistance of the product against sudden force

DC Voltage Overstress

The DC Voltage Overstress Test using a power supply to applies 18 VDC for 5 minutes. For Heavy Duty products 24Vdc is applied for 5 minutes to simulate a vehicle that is jumpstarted.

Mechanical Durability Cycle

Jensen test individual components, as well as fully operational systems. Test include environmental conditioning, while , structural durability tests pressure and electrical inputs. Jensen Heavy Duty Marine TVs undergo Life cycle robotic testing of all buttons and hinge mechanism for durability.
