IRS-2000 ҹͧǺҧѺ

RSS/2W เปลี่ยนไปตามแรงดันไฟ ไม่เกิน 70v ใช้ค่า 4.7k/2w แรงดันเกิน 90v ใช้ค่า 6.8k/2w
RFB R ป้อนกลับควบคุมเกนขยาย ใช้ค่าตั้งแต่ 68k-220k แล้วแต่ชอบความแรง ส่วนใช้อยู่ที่ 100k
R OSC ใช้ค่า 1k

ic gate drive ir2110
ic inverter cd4049
ic compara input TL071CP
ic protection ใช้ 2 ตัวบนซ๊อกเก็ตเดียวกัน ตัวล่างสุดนับตั้งแต่ขา 1 ของซ็อกเก็ต ic 8 ขา LM311 ตัวที่ 2 ic NE555N เป็น ic
8 ขาเหมือนกัน โดยใส่ลงบนซ็อกเก็ต ต่อจากดัวล่างได้เลย

อย่า งง. ไอซีตัวแรกล่างสุด lm311 แล้วใส่ต่อกันเลย ตัวที่ 2 ne555n รวม 2 ตัว 16 ขาพอดีกับซ็อกเก็ต โดยให้ขาที่ 1ของ
ไอซี ตัวที่ 2 ne555n อยู่ในแถวเดียวกันกับตัวที่ 1 ก็

สรุปก็คือ ไอซี 2 ตัวหันไปในทิศทางเดียวกัน
ข้อสังเกต ไอซีตัวที่ 2 ne555n มักไม่ถูกใช้คือไม่ใส่เลย อาจเพราะระบบโปรเทค ตัดบ่อยเมื่ออัดแรงๆๆ
ขอให้ผ่านและสำเร็จ กับระบบการทำงานของ คลาสดี irs2000

RSS/2W changes according to the voltage up to 70v or 90v power 4.7k/2w use 6.8k/2w.
RFB R feedback control of the House. Values ​​ranging from 68k-220k, depending on your strength. The use of the 100k.
R OSC for the 1k.

ic gate drive ir2110.
ic inverter cd4049.
ic compara input TL071CP.
ic protection to the upper left 2 the same socket. Since one of the bottom leg socket ic 8-pin LM311, which is 2 ic NE555N ic.
8 foot by pushing down on the same socket. From Dallas to see it.

I do not. Lm311 circuit first and then put the bottom on the second 2 ne555n include a 16-pin socket to fit on the first leg of
C at 2 ne555n in the same row with the 1's.

Short circuit 2 is turned in the same direction.
Note that C 2 ne555n are not being used, is not it. Probably because Pro Tech. I often cut on the compression strength.
The past and success. With a good system of irs2000.
