Notebook guard

The notebook protector

Micro System Services offers field-tested patent pending, secure power protection system especially for laptops called Notebook Guard. It is IC based, fully automatic Lightweight device.

How it works.

Notebook Guard is connected at before the laptop adaptor. Incoming current will first pass through Notebook Guard then into the adaptor. Notebook Guard continuously monitors the line voltage. Whenever the voltage is above or below the set voltage limits the Notebook Guard simply cuts the voltage to the laptop thereby saving it from the line disturbance. It reacts within fraction of second to the disturbance. Notebook Guard will withstand the voltage even as high as 440Volts.It however does not stabilize the voltage as in the case of other devices in the same category like Stabilizer, CVTs.

When the voltage returns to normal , the Notebook Guard resumes the supply to the equipment with short power-on delay of 3 seconds(configurable). This feature is called the Smart Start. It prevents the initial harmful transient that may damage the Equipment.

Features:

• IC Technology
• Under/over voltage protection
• Protection up to 440 volts
• Withstand up to 6000V spikes
• Smart start
• Over load protection
• No wave form distortion
• Line monitoring indication

Under voltage and Over voltage Protection

Unpredictable load changes, over voltage can exceed up to 300V and above. Under voltage result due to excess load in the line, this result in system crash, freezing of keyboard and corruption of data are mostly due to extreme under voltage. Notebook Guard stops supplying power to the laptop, safeguarding from such effects.

Protection up to 440V:

Electrical hazards 440V is an unpredictable occurrence; often the consequence can be a total capital writ off of equipment. Sudden high voltage of 440V can be cause by one of the power lines getting cut, unbalanced load or neutral floating or a tree, pole, pillar falling on main power line. In such cases MCBs, fuses, which monitor only currents, will not be able to contain the voltage shoot-up. Exposed to such a condition any device will be damaged or even fried. Such situation usually occur in outdoors, sites. Notebook Guard can withstand a voltage of up to 440V. The 440V protection feature has been tested by ERTL (Electronics Regional Test Laboratory.)

Smart Start:

In such occurrence Notebook Guard starts supplying power to the laptop with a short delay of 3 seconds where initial surges and transients, which are harmful, get eliminated. NOTEBOOK GUARD carries out this function un-manned.

Spikes and surges suppression:

Spikes and surges are result of sudden changes in electrical load. It occurs then switching on; electrical equipment’s like motors, power tools, and air conditioners, welding machines fluorescent lights. Spikes and surges in power lines cripple or burn computer, data handling equipments, Needles to say corrupting data in it. Surges are fast rising peak with short duration of less than a microsecond. The peak voltage can rise to several thousand volts within a fraction of seconds. Notebook Guard incorporates surge suppression technique to give maximum protection to equipments. The suppression test is certified by ERTL (Electronics Regional Test Laboratory.

Overload protection:

It is more often over current than open circuit that causes fire, if not contained quickly within a safe period can lead to disasters involving life and property. Fuses deployed are neither fast nor accurate enough to take care. They cause tripping which can jeopardise a production stoppage without solving the problem. Notebook Guard provides overload protection intelligently.

Earthing:

Earthing is critical for electronic equipments safety. Most of such products are exposed to burnouts because the circuitry used in them cause’s raw power to flow to the earth line thereby making all equipments live. Highest safety principles need to be adopted in designing and manufacture. Notebook Guard indicates prevalence of such situation to rectify it.

Stabilizer Issue?

SMPS itself are the best stabilizer in the world. In-fact, it has wide operating range than most stabilizer and gives rock steady regulated power supply. Thus stabilizer before SMPS is of no use. This means when the voltage fluctuation is within the range of SMPS, it will protect its load from unregulated voltage supply. As such Stabilizers will not solve above mentioned issues
