隔離牛製作班x電源線材製作班

還有型仔soft start 開關掣,很多人說開牛時彭一聲就係咁

仲支持ext 12V trigger

可用AV amp 開番佢轉頭

個開關button 超型

Andy,

read your link, do u know what happen if the Center tap is not center?
i.e. un-balance of two side.

Softstart







Standby power 0.7W.

Max handle power 3.5KW.

Designed by KK.Ho

This module will available at coming course. (Option parts).

All,

this course is held by Modi and Admin.
I only provide the Softstart design....

Don't ask me how much... Thanks.

剩係個DAC己經令你大出血

快回覆
KK 祇回答softstart 查詢

10片夠用嗎?

焊左一個下午

十二人參與要預備12塊softstart了

Andy,

No, absolute complete module.
1. All SMD (Resistors and capacitor) are 0603 package. Most (99%) cannot handle.
2. The major part (RELAY) is using TYCO brand, no worry, it is a very good component that I choose for it.
3. Another components such as SMD IC, fuse stand, etc are not affect the sound quality. No need black gate, jensen, etc.

What I can let you solder?
It have 4 input terminal and 4 output terminal, I can let it empty and let you direct soldering the wire on the PCB.

For additional softstart module, please contact admin@hififever.com, I will arrange more set to you if need. (Complete unit)

我斬開二條fuse 是有原因的
線路，負載獨立保護

6.3A Slow blow fuse onboard for load.
500mA normal blow fuse onboard for softstart circuit. (Basically I want to use 250mA, but hard to find the lead leg fuse type)

空手上來便可以。
這裡有齊工具。

另外softstart module 係option part.
加上這版本外面暫時係無得賣住，衹供hififever用
(有我個大名)

Softstart 用途另外文章刊登於技術資料區(11-Sep上載)

K哥字

Softstart module include:

Softstart board x 1
Terminial x 4 (2 in, 2 out)
Fuse terminal for load x 1
3.5A slow blow fuse x 1
5.0A slow blow fuse x 1
Switch terminal (plug + socket + 2 pin) x 1
Toggle Switch x 1 with cable (20cm)

Andy Poon,

1. You can soldering your AC input wire to this board.
2. For the fuse, you can use 2 in 1, but must keep the small rating fuse on board. (Already solder on board).
3. Take the output from Mainboard, Neutral = In and out (Share point)
  Before fuse stand connector --> Live output.
4. Toggle Switch, Bi-Color LED is 4 pin wire cable, no need any special.

開机不久燒FUSE，
請問負載是什么東西，如果你是1500VA 牛，請用6.3A fuse.

袋中有二條FUSE，一條係3.5A，一條係5A，彈簧型慢燒。

所以"保護裝置". 是非常重要的. 又一次證明.

吾好亂換Fuse.

1. 是否一開就燒？
2. 你所接駁的架生？
3. Softstart 會頂開机inrush current, 如果你average current 大於6A，一樣會燒斷，呢樣係保護。
4. 開隔離牛時，負載應先關。

最後一句，Fuse 易斷好過一世吾識斷。

Modi,

我報充少少
情況1 以隔離牛為開關)，所有架生已ON
Softstart 保護時間約1秒(其實約半秒)，負載那inrush current 長於1秒並電流大於6A，咪燒fuse.
如果負載開机inrush current < 2 sec, softstart 可調timming.

情況2 負載關，先開隔離牛
逐個擴音開，或者開到第二個後級燒。
你個後級inrush current >6A 好多倍。
已開著第一個，巳取了2A，再開第二個，咪燒。
解決方法:
分開兩隻牛
或softstart fuse 改用6A彈弓果種愎燒.

清吾清楚。

(一部好設計的後級應該有softstart 防止開机inrush current 及average current 過大也會保護。)
