The 69920 Universal Arc Lamp Power Supply is used to power 450 W and 1000 W solar simulators. It is highly regulated and maintains a very stable light output. For long-term stability-critical applications, the Digital Exposure Controller is recommended. It compensates for factors beyond the power supply’s control, such as lamp aging, electrode erosion, and gas absorption. The 69920 has an RS-232 computer interface in order to set the lamp operating parameters, monitor the light output levels, and turn power on/off remotely.

69920通用弧光灯电源用于450 W和1000 W太阳模拟器。它是高度调节和保持一个非常稳定的光输出。对于长期稳定关键应用，建议采用数字曝光控制器。它可以补偿电源无法控制的因素，如灯老化、电极腐蚀和气体吸收。69920有一个RS-232计算机接口，以便设置灯的操作参数，监测光的输出水平，并远程打开/关闭电源。
