(3)Staticcurrentmode[
C-FB
]
If temperature coefcient of load (platinum, molybdenum, tungsten, etc) changes 6 to 12 times
based on room temperature, it outputs constant current which is proportion to control input not to
change output voltage for power supply variation, load resistance variation.
(4)Staticpowermode[
Y-FB
]
It outputs constant power which is proportion to control input even though load variation and
power supply variation. It is proper control method for a heater which resistance value variation by
carbide(SIC) heating is big.
Output characteristics is proper 50% of the curve which connects the point (A) [output voltage
100% × output current 50%] and the point (B) [output voltage 50% × output current 100%].
The current output capacity of this unit should be over two times of load capacity.
