AC Power Source
Programmable AC/DC Power Source
KP3000S/KP3000GS

*
Stable Output
*

*Low distortion *Low output noise *4 times the maximum current


Low distortion, low noise, and stable output are achieved. This power source can supply stable power to various types of loads such as inductive and capacitive loads for low power-factor loads such as equipment with large-capacity noise filters and large power output transformers.
Also, with its high-quality waveform output, this unit can be used as an AC stabilized power source for precision measurements such as the power consumption and standby power of electronic equipment.

Variable Current limiter Function
*

*Current RMS value *Positive/negative current peak value

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, etc. and protecting against abnormal current caused when prototype operations fail.

Various Types of Output
*

*AC mode *DC mode *AC + DC mode
With AC 3 kVA, full-power 3kW output is also available for DC. The capacity is not reduced in DC mode. Since the AC+DC mode is also available, this power source can be used for a variety of applications.
A high S/N ratio is achieved in each mode. Use of the current limiter function in DC mode enables the high performance use of the unit as a DC power source. In addition, in AC+DC mode, simulations can be performed in which the DC component is generated temporarily, such as a sudden change in voltage.

Output Voltage Correction
*

There are cases where a voltage drop occurs at the load end due to wiring. The KP3000S/ KP3000GS are 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)
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
*

*Sine wave *Clipped sine wave*Arbitrary 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.
