特長
- 当社の顕微鏡用Solis® LED用に設計
- LEDの発光強度はダイヤルで容易に調整可能
- 電流リミット値の自動設定でLEDをオーバードライブから保護
- 最大駆動電流:10 A
- LED最大順方向電圧:14 Vまで対応
- BNCコネクタから外部TTL変調信号を入力可能
ドライバDC20は当社のすべてのSolis LEDを簡単に制御できるように設計されています。設定や使用方法も簡単で、タッチパネル式LEDドライバDC2200の高度な機能までは必要としないSolis LEDのご利用者に便利な製品です。ドライバDC20ならびにDC2200の比較については「Solis LEDドライバ」のタブをご覧ください。
LEDに供給される電流は、ドライバ上部のノブを回すことにより制御します。上部パネルのLIMITと記載された位置は、接続されたSolis LEDの最大電流値に対応します。ドライバはSolis LEDの内部メモリに保存された電流リミット値を自動的に読み取ってドライバに設定し、LEDをオーバードライブから保護します。ノブを押すと、LIMIT位置に対するその時のコントロールノブの位置(比率)に応じた電流値でLEDをオンにするか、またはオフにします。また、ドライバの筐体背面にあるBNC入力端子に外部TTL信号を入力して、LEDを変調することも可能です。なお安全のため、TTL変調の機能を使用する前にドライバの電源を手動でONにしてください。TTL信号の要件については「仕様」タブをご覧ください。
ユニット側面の3色LEDは接続されているLEDのステータスを示しており、LEDのオン・オフ(赤外LEDには便利)、LEDが正常に動作しているか、エラーが発生していないかといった情報が表示されます。
なお、ドライバDC20は当社のSolis LEDの内部エレクトロニクスに特化して設計されているため、そのほかのLED製品の駆動には使用しないでください。
当社ではマウント付き、コリメータ付き、ファイバ出力型、PCB実装型などの各種LEDに対応するLEDドライバもご用意しております。LEDドライバの種類については下表をご覧ください。

2、TTL Modulation Mode,在频率在100hz-1000hz时,led就灭了 hchow
 (posted 2024-10-16 03:31:09.0) 你好,黄先生。DC20-SP1 与 DC20 相同。只是安装了不同的固件。它停用了旋转旋钮的按压功能。这意味着只要 DC20 接通电源,LED 指示灯就会有电流流过。电流的大小由旋钮的位置决定。TTL 功能得以保留。我们的中国 Thorlabs 技术支持团队将与您联系。 Mark Handschy
 (posted 2023-05-05 06:55:41.193) It would be handy in the specs for the DC20 to indicate what SENSE the TTL control has. We all know what the standard high & low TTL voltage levels are. What we don't know is whether pulling the TTL IN port high turns the lamp on or turns if off. hkarpenko
 (posted 2023-05-08 11:42:15.0) Dear Mark,
thank you for your feedback. You are right, we don´t specify this in the specification tab directly on our website. However you can access this information in the more detailed manual we have written for the DC20. On p.8 we explain the modulation application. As long as the TTL input is open or High, the SOLIS is enabled and supplied with the current that is set by the rotary knob. A TTL Low level disables the SOLIS. Per Grön
 (posted 2023-05-04 23:08:40.68) Hello,
I am a great fan of Thorlabs, your products are normally great and meet my needs perfectly. Unfortunately, this is not the case for DC20. The product information on your website describes the TTL control option as an alternative to controlling it with the push button "Alternatively, the LED can be modulated using an external TTL signal" but this is not how the product works: You can either turn on the light with the push button, or you can turn it on by first pushing the push button and then using the TTL signal. TTL is not an "alternative" to the push button because it can't be used without it.
I have the SOLIS-1D in a machine in that has many components that are all controlled by a PC. This machine would not be practical to use if each component required the user to manually control it during use, but the DC20 requires just that.
The DC20 is even "smart" enough to not turn on if the push button is pushed at the time of boot so it's impossible to hack around it by always pushing the button, however it is not smart enough to remember the previous setting after a power cycle.
There are so many ways in which the DC20 could have been usable in this application: Make it remember the state on power cycle, use a switch instead of a push button, allow the TTL input to actually turn on the lamp, allow me to physically depress the push button at all times to turn it on... As it is now it seems like I will have to find some other LED driver or to hack the circuit so I can simulate button presses.
This is not helpful design, and the product documentation gets pretty close outright lying about how the TTL feature works. If I would have known that the TTL output does not work without the push button I would not have bought the device.
Kind regards,
Per hchow
 (posted 2023-05-05 10:28:20.0) Dear Per Grön, thank you for your valuable feedback. I will let the developers know about the issue you are facing with our DC20. Meanwhile, I will personally reach out to you to find a solution for the problem you have with your DC20. |
当社ではSolis® LED駆動用に2種類のドライバをご用意しております。DC20はベーシックなモデルで、LEDの発光強度は上部のコントロールノブと、変調用の外部TTL信号入力端子を用いて制御します。より高度な用途向けのドライバDC2200では、タッチパネル式のインターフェイスからLED電流の制御、内部または外部変調モードの選択ほか、様々な操作ができます。下表では主なコントローラの特長の比較がご覧いただけます。
