1) Summary  

• The circulating voltage and electric current and its circulating time and the stopping time may be changed according to one's needs within a varying scope to allow user to match it to the most suitable state.

  In the case of the distance length with opposite poles being far due to a large number of refracted sections in the conversion coating (low electric current section), approximately 1.5 times the normal circulating voltage is added making the circulation smoother and it also prevents damage on the surface's condition and allows for repetitive circulation with a momentary and sustainable termination time in order to control local heat.  

2) Characteristics

•  DC 12V 2000A 30KW , frequency varying scope 5Hz ∼1KHz , Duty ratio ON TIME 20∼80% At Pulse Mode operation duty ratio 50 : 50 %, rectifier operation rating is 7.5V 1000A.

4) Detailed movement content & waveform

Frequency = t1+t2 ⇒ 5㎐ 1KHz when setting frequency the 1 cycle time t1 time and t2 time gets decided automatically. (At this time D50% at time of setting t1 : t2 = 1:1

• t1 : 1 cycle outputting an electric current cycle, t2 : Output terminating cycle
• t1 time meaning that the value of a circulation period is able to vary up to 20∼80%.
• According to duty ratio (D: xx %) t1 time gets controlled, remaining time t2 time 1-(t1xx%)=t2

Ex) At time of setting frequency to 100 Hz, 1 cycle f = 1/t = 10ms
At D=50%, t1 = 5ms , t2 = 5ms
At D=80%, t1 = 8ms , t2 = 2ms *10ms * 80%= 8ms(t1) 10-8=2ms(t2)*

t1 : 0.5ms∼999ms (time variable scope)
t2 : 0.5ms∼999ms
1000Hz ∼5Hz (Frequency variable scope)
20~80% gets set and used regarding T1 of 1 cycle time
