Design Features:

The SPD3303C exhibits high resolution, 10mV / 10mA, providing the user with excellent settability and read back accuracy. In addition, it maintains its ability to change output voltage or current in small increments while fully meeting the power requirements of the load.

Series/parallel/independent output modes. Series-parallel functions combines two power supplies into one and makes it very convenient for many applications. It has three independent outputs which can be controlled separately, can also be turned on or off at the same time, making it versatile and very easy to use.

Panel timing output functions. Five output timing profiles are settable via the SDP3300’s front panel. Each profile is independent of the others and allows settable voltage and current values. The timer function allows for continuous output with profiles as long as 10,000 seconds / profile. In addition to easy front-panel control, the SPD3300 power supplies come with SIGLENT’s EASYPOWER PC software.

Save/ Recall interface. The SPD3000C programmable linear DC power supply provides five groups of local storage system parameters and has support for external memory expansion. With this feature the local or external memory can be stored,recalled,or deleted, making it easy to return to your desired settings.
