PCB : WHY PCB IS CEM1 MATERIAL?
excellent electrical properties and higher flexural strength ,flame-retardant
SPIKE VOLTAGE RESTRICTOR :
WHILE SUDDEN SPIKE VOLTAGE OCCUR BY LIGHTENING OR GENERATOR POWER SOURCE THIS WILL THIS MOV WILL PROTECT THE CIRCUIT BOARD. WE ARE KEEPING 2 COMPONENTS IN ORDER TO PREVENT THE SPIKE VOLTAGE PROPERLY.
USA BASED IC:
THE HEART OF THE POWER SUPPLY IS POWER IC. THIS INTEGRATED CIRCUIT ITSELF HAVING THE FEATURE OF Current Limiting, Over Load, Over Temperature, Over Voltage, Short Circuit - protection,with the operation temperature of -40°C ~ 150°C .
NOISE FILTER:
Capacitors and inductors work together to cut down noise on the supply line.
RESETTABLE FUSE:
THIS PPTC COMPONENTS IS THE MAJOR COMPONENT IN THIS CIRCUIT TO SEPARATE THE EACH CHANNEL 1A AS A CURRENT LIMIT. THIS WILL PROTECT THE POWER SUPPLY WHEN THE OUTPUT/CABLE IS SHORT CIRCUITED.
CAPACITOR:
THIS CAPACITOR IS WITH 8000H DURABILITY WITH LOW RIPPLE NOISE. (NOTE MOST OF THEM ARE JUST USING 2000H CAPACITOR TO REDUCE THE COST(VIRTUALLY THE QUALITY)
GENERAL QUESTION & ANSWER :-
1*. *WHY THE PRICE IS HIGH?
*A*. THE QUALITY PRODUCTS AND THE CHEAP PRICE IS ALWAYS INVERSELY PROPORTION TO EACH OTHER. The price is depends upon the raw material and components used in the power supply. some of the domestic manufacture are used to remove the major components for cost cutting. (ie) if we are removing only the *PPTC RESETTABLE FUSE*,per combo we can save *25Rs*.but the quality will be compromised.

2*. *WHY POWER SUPPLY IS NOT SUPPORTING IN THE LONG DISTANCE 3+1 CABLE?
A*. NORMALLY ALL THE CMOS CAMERA WILL WORK EVEN WITH *300ma CURRENT AND DURING NIGHT WITH IR ILLUMINATION 600ma CURRENT IS SUFFICIENT.
HERE THE PROBLEM IS WITH THE CABLE.WHETHER ITS PURE COPPER CABLE OR METAL OR ALLOY*?ALSO WHAT IS THE WIRE GUAGE? (ie) *DC 1A CURRENT CAN CARRIES VOLTAGE JUST 10 METER WITH 22AWG COPPER CABLE WITHOUT LOSS.SIMILARLY IT WILL TRAVEL 100M WITH 12AWG CABLE. IF WE EXTEND IT WILL LOSS OF ENERGY.
TO OVERCOME THIS WE HAVE 3 OPTIONAL SWITCH NORMAL/LONG/EX-LONG. NORMAL WILL GIVE 12.5V AND LONG WILL GIVE 13.5V*SIMILARLY EX-LONG WILL GIVE *15V FOR COMPENSATING THE LOSS OF VOLTAGE IN THE DISTANCE.SO TO OVERCOME THIS PROBLEM *PROPER COPPER CABLE SHOULD TO USE FOR BETTER PERFORMANCE*.
3*. *HOW ABOUT THE PRODUCT RELIABILITY?
*A*. ALL THE PRODUCTS ARE KEPT UNDER LOAD AND AGEING TEST.SO THE PRODUCTS ARE MORE RELIABLE FROM FAILURE AT THE SITE.
