RCD-24 Series

  • UL/ RAILWAYS Certified Constant Current LED Driver
  • Wide Input and Output Voltage Range
  • Digital PWM and Analogue Voltage Dimming
  • Short Circuit Protected
  • Pinned or Wired Versions
  • IP67 rated for /W Version
  • 96% Efficiency
  • 5 year Warranty

The RCD series is a step-down constant current source designed for driving high power white LEDs. Standard output currents available are 300mA, 350mA, 500mA, 600mA, 700mA, 1000mA and 1200mA to make this driver compatible with a wide range of LEDs applications. Despite its compact size, the RCD series is fully featured with very high efficiency, wide input voltage range, high ambient operating temperature and two means of dimming: PWM/digital control and analogue voltage dimming. Both dimming controls are independent and can be combined. The driver is also designed to be as reliable as the LEDs it is driving, even at the full operating temperature. Options include an IP67-rated wired version (/W) and a version with built-in reference output voltage (/Vref) to power sensors or for easy analogue dimming.

    PWM制御ピンは、リモート制御ピンとしても使用できます。つまり、このピンからユニットのオン/オフを切り替えることができます。スイッチングレベルはTTLと互換性があり、低速スイッチング波形を可能にするヒステリシスがあります。
    PWM調光の10〜90％の範囲外での直線性は完全ではありませんが、それでもかなり良好です。アナログ調光は0〜100％の範囲で使用できます。
    アナログ電圧は、内部PWM回路の制御に使用されます。
    RCD-24シリーズは降圧型（バック）コンバータなので、常に必要な出力電圧よりも高い入力電圧が必要です。通常、高出力LEDの順電圧降下は約3.4Vなので、12Vの電源から直列駆動できるLEDは3つだけです。入力電圧を24Vに上げると7個のLED、36Vの場合、10個のLEDを駆動できます。
    ただし、LEDチェーンを並列接続することが可能であるため、RCD-24-7.0は、並列に接続された3つの350mA x 2つのLEDチェーンを駆動できます。
    この部品は定電流コンバータであるため、出力電圧は必要な電力に応じて可変ですが、常に入力電圧よりも低いことに注意して下さい。
    RCDシリーズは、高効率、広い入力範囲、アナログおよびデジタルの2つの異なる調光方法（PWM）、広い動作温度範囲を備えた小型パッケージのオールインワンソリューションであり、完全にテストされています。異なるサプライヤからの全てのコンポーネント、個別のソリューションについて心配する必要はありません。
