Siglent SPS6150X One Channel, 100V/50A/1500W Switching DC Power Supply

The SPS6000X Series is a programmable switching DC power supply with a wide range of single output and constant power features. This series includes two models, the SPS6225X and SPS6150X, which feature rated output voltages and currents of 200 V / 25 A and 100 V / 50 A, with a maximum output power of 1500 W. Users can connect up to five SPS6000X chassis of the same model in parallel to expand the output power to meet different application requirements. The SPS6000X series has a high brightness 3.12 inch OLED display, a user friendly interface that enables easy control and performance monitoring, and excellent performance indicators. The minimum resolution is 10 mV / 10 mA. The output voltage and current rise times are adjustable. It has two output modes: Constant voltage and constant current. It also supports list sequence programming mode to easily perform voltage or current step profiles. Safety features include over voltage, over current, power limit, and over temperature protection. For remote control operation, the SPS6000X includes LAN / USB communication interfaces, an analog control interface, and a convenient web browser control.

Constant Output Power

In constant output power mode, the voltage and current range are switched automatically to maximize the voltage and current without sacrificing the supply’s output power.

Adjustable Output Voltage, Current rising/falling Slew Rate

The power supply supports custom rise/fall slew rates of both voltage and current to verify the performance of the device under test as the voltage/current changes. This feature can effectively prevent the damage caused by inrush current to the DUT in applications such as the testing of capacitive current absorbing devices.
