HJ-PST系列亮度可调电源提供光源亮度的连续调节，每通道输出电压为12V或24V，可以利用外部触发实现频闪功能，以提高光源的亮度、延长光源的使用寿命。
You can use the external trigger to achieve the strobe function to increase the brightness of the light and extend the service life of the light.
HJ-PST系列电源的特点
① 亮度可调控制
② 外部触发频闪：将相机的触发信号输入到控制器，使光源进行频闪照明，适度提高光源的亮度，延长光源的使用寿命。控制器分正触发和负触发两种外触发方式，每种触发又分2种触发模式：电压触发和开关触发。正触发（常亮）：电压触发时，高电压5-24V光源亮，低电压0-1.5V光源灭；开关触发时，断开状态光源亮，短接状态时光源灭。负触发（常灭）：电压触发时，低电压0-1.5V光源亮，高电压5-24V光源灭；开关触发时，短接状态光源亮，断开状态光源灭。
Features of HJ - PST Series power
① Adjustable brightness control
② External trigger strobe: The controller has two kinds of external trigger, the positive trigger and the negative trigger, and each trigger is divided into two kinds of trigger modes: voltage trigger and trigger switch. The positive trigger (Always ON): when using voltage trigger, the light with high voltage of 5 - 24V is on and the light with low voltage 0 -1.5V is off; when using trigger switch, the light is on when disconnected, and the light is off when short circuit. Negative trigger (Always OFF): it always contrary with the positive trigger(Always ON).
