Product Functions

  • Measurement function
    • In addition to voltage, current and power, the DP Series optionally supports measurement of load power factor, crest factor, and up to 40th order harmonic current. In addition, the series supports measures to control CO2 by displaying CO2 emissions during operation
    • 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 (Option)
      • Harmonic current: Up to 40th order (Option)
      • Load power factor (Option)
      • Crest factor (Option)
      • Sync frequency
      • CO2 emissions
  • Simple operation
    • Panel operation is a breeze using the large, easy-to-read display. The design stresses improved ease-of-use and work efficiency for users, with features such as a function for selecting three decided measurement items and displaying them enlarged, and remote operation using a remote controller (See photo section)
  • Current limiter function
    • Output current limits can be set with peak value and RMS value. With peak value setting, both positive and negative current values can be set. It is possible to continue output current limitation after limit operation using a setting, or to turn output off after continuing the limited state for a set time. When evaluating a prototype, this is useful for protection in case there is an abnormal current due to abnormal operation of the load
      • Setting: Positive/negative peak current value and RMS current value
      • Limiter operation: Self-recovery (continuous) or output off.  Possible to designate the time to continue the limited state until output off (1s to 10s, resolution 1s)
  • Protection function
    • The DP Series have a built-in protection function for protecting the power supply itself if a problem occurs due to issues such as output overvoltage or overcurrent, power unit trouble, internal control problems in areas such as the operation panel or communication, a rise in ambient temperature, or a drop in AC line voltage. If a problem occurs, it is displayed on the panel and output is turned off. This is used together with the current limiter function for protection against overcurrent, and it is possible to select either self-recovery after elimination of the problem, or output off after a designated time
  • Set range limit function
    • This prevents load malfunction due to mis-operation or other problems by limiting the setting range for the output voltage upper limit and the frequency upper and lower limits
  • Remote sensing/AGC/Auto Cal
    • There are cases where a voltage drop occurs at the load end due to wiring. The DP Series is equipped with functions to always supply the set voltage
  • 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) (Option)
    • This function performs continuous correction to ensure a match between the RMS values of the detection point voltage and the output voltage setting. Correction is performed automatically to maintain the same value as the setting value, even if the load fluctuates
  • Autocal (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
  • Memory functions
    • Save/load settings from nonvolatile memory. Basic settings (30), sequences (5), simulation (5), arbitrary waveforms (16), Clipped sine waves (3)
