KP3000GS (3kVA AC, 3kW DC Programmable AC/DC Power Source)

產品功能

• Variable current limiter function
  • Output current limiting can be set with positive and negative peak values and effective value. After the activation of the limiter, the output can be automatically restored or turned off after a set time. This function is effective for limiting the rush current of motors, large- capacity capacitors and protecting against abnormal current caused when prototype operations fail
• Remote sensing
  • Switches the voltage detection point used for measurement and output voltage correction to either output terminal or sensing input terminal. Output is corrected by using this together with AGC and Auto Cal
• AGC (Automatic Gain Control)
  • This function performs continuous correction to ensure equality between the RMS values of the detection point voltage and the output voltage setting value. Even if the load fluctuates, correction is performed automatically to maintain the same value as the setting value
• Auto Cal (Auto Calibration)
  • Each time Auto Cal is turned on, this function measures the detection point voltage and performs correction to ensure that the output voltage RMS value is equal to the voltage setting value
• Output waveform
  • In addition to sine waves, clipped sine waves and arbitrary waves can be output. A power source test is supported that can simulate a fault in a commercial line. A clipped sine wave can be set with a crest factor or clipping ratio. An arbitrary wave can be easily created by using the optional control software and can be saved for reuse in the main unit memory through an external interface or in USB memory (See photo section)
• Measurement function
  • Abundant measurement functions comparable to those of a wattmeter are provided. Three measurement values can be selected for enlarged display to improve working efficiency in production lines
  • Measurement items
    • Voltage (RMS value, average DC value, peak value), current (RMS value, average DC value, peak value, peak hold value), power (active power, apparent power, reactive power), load power factor, crest factor, sync frequency, harmonic current (up to 40th order), CO2 emissions
• Sequence function
  • Programming of various test patterns such as test repetition, combinations of complex test conditions and long-term testing enable automated test sequences. Power source tests for each destination can be performed efficiently. When purchased with the optional control software, this power source can be freely programmed with very long and complex output patterns
    • Number of steps: 255 (in 1 sequence)
    • Setting items: Step time, output range, AC/DC mode, DC voltage, AC voltage, frequency, waveform, start phase, stop phase, phase angle, step termination, jump count
    • Sequence control: Start, stop, hold, resume, branch 1, branch 2
    • Number of memories: 5 (Non-volatile)
• Simulation function
  • The KP3000GS simulates a problem in the power AC line such as blackout, voltage rise, voltage drop, abrupt phase changes, or abrupt frequency change, thereby enabling all types of AC line simulation such as prototype evaluation and product inspection. When purchased with the optional control software, the KP3000GS can be easily programmed with various test conditions
    • Number of steps: 6 (Initial, Normal 1, Trans 1, Abnormal, Trans 2, Normal 2)
    • Setting items: Step time, output range, AC Voltage, frequency, start phase, stop phase, trigger output
    • Waveform: Sine wave
    • Number of memories: 5 (Non-volatile)
• Control software (Option)
  • The control software enables basic parameter settings, data logging, arbitrary wave editing/transfer and sequence editing/ control. It supports automation of measurement data analysis in product development and of various tests in production lines (See photo section)
