产品描述：
PCX-7420 能够提供 QCW（脉冲）和 CW（DC）输出。它可以在 0.050 A 到 5.8 A 的电流下用作 CW 驱动器，在 3 A 到 21.5 A 的电流下用作脉冲/QCW 驱动器。此外，输出可以偏置到从 3 A 到 5.8 A 的任何 CW 电流，然后以高达 15.7 A 的最大电流脉冲高于此偏置电流。一项新功能允许偏置电流独立于主电流触发器进行脉冲和触发。
PCX-7420 旨在驱动二极管激光器、棒和阵列，正向压降高达 24 V。
Product Description：
The PCX-7420 offers the capability of providing both QCW (pulsed), and CW (DC) outputs. It can serve as a CW driver at currents from 0.050 A to 5.8 A, and as a pulsed/QCW driver at currents from 3 A to 21.5 A. Furthermore, the output may be biased to any CW current from 3 A to 5.8 A, then pulsed above this bias current at up to 15.7 A maximum. A new feature allows the bias current to be pulsed and triggered independent of the main current trigger.
The PCX-7420 is designed to drive diode lasers, bars and arrays with forward voltage drops up to 24 V.
