 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.

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.

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.
|
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.
