SPS Series DC Power System
parameters
It can provide stable DC output, built-in voltage and current testing capability, and can provide a wider combination of voltage and current in the whole power range, with a single machine range of 12kW to 40kW, a current range of up to 2000A and a voltage range of up to 1200V, which can meet the application of various DC power supplies. The user can arbitrarily set the output voltage and current, and measure the characteristics of the output, which are displayed on the VFD. At the same time, the power system provides a variety of standard communication interfaces to simplify and speed up test development.
This function is suitable for testing the current carrying capacity of the cable/fuse. When this function is turned on, the power supply will turn off the short-circuit protection function and maintain the very low voltage output rated current.
This series of power supplies supports 3 LIST file editing formats to meet the output elements under different test requirements, and the minimum resolution of the setting time is 1ms.
Pulse File Format
You can set the trend and duration of the output voltage over time, and set the mode of output waveform execution according to the requirements, LOOP (cycle),CONT (single),STEP (single step).
Slope File Format
The file format supports the slope setting of the output voltage, realizes the slow rise and fall of the output voltage, and sets the execution mode of the output waveform according to the requirements, LOOP (cycle),CONT (single),STEP (single step).
This function is an upgraded version of LIST file editing. Each step of the file is a complete LIST file. This function can combine and output several LIST files, and can set the number of repetitions of each LIST file and the number of executions of the entire SEQUENCE file.
In this mode, if the object to be measured has drastic voltage and current changes, the average measurement times can be changed to make the display value more stable. The display frequency has FAST (fast)/MEDIUM (medium)/SLOW (slow) to choose from.
This function is applicable to circuit breaker or fuse blow time test. When the current reaches the fuse current Ib of the circuit breaker or fuse, the timing starts, and the timing ends after it is disconnected, and the timing resolution can reach 200ms.
