
Sequence function
When using an internal signal source, the output parameters (output voltage, current, output
frequency) can be sequentially changed or swept, and by programming output changes beforehand,
outputs with specific patterns can be supplied.
 
Vo limiter,

Io limiter function
The maximum values of the output voltage (Vo) and output current (Io) can be independently set for
each polarity. The output voltage and current are limited to these values.

Output voltage range expansion function
The output voltage amplitude range can be set to symmetric or asymmetric with regard to the
polarity. Using the

Vo limiter function, the output voltage range can be set to a maximum of 120
Vp-p including 0 V within the range of

115 V to +115 V. For example, the output voltage range can
be set to the ranges of

60 V to +60 V,

5 V to +115V, or

115 V to +5 V. Since the suppliable
output current range changes according to the output voltage range setting, the optimum setting
range can be selected from the required voltage and current.

Response calibration function
The amplifier response characteristics can be selected between fixed characteristics and user
adjusted characteristics. Fixed characteristics are characteristics that emphasize both broad
frequency band characteristics and load stability (during CV, DC to 35 kHz,

3 dB, during CC, DC
to 8 kHz,

3 dB). In the case of user adjusted characteristics, the response characteristics actually
adjusted by the user according to the load conditions can be used. Adjustments of the output voltage
and current waveform are performed by moving three adjustment knobs on the internal part of the
operation panel for the time constant, voltage feedback amount, and current feedback amount, while
watching an oscilloscope.

Output voltage and output current signal monitor output
The monitor ratio for the voltage is 1/100th of the output voltage, and the monitor ratio for the
current is 1 V/20 A, both in phase.

Measuring function
This function is used to measure and display the output voltage and current (DC value and P-P value
for each).

Output on/off function
During output on/off switching, the output level (output voltage during CV, output current during
CC) is lowered to 0 and then output relay opening/closing is performed to minimize contact arc.

USB interface provided as standard
External control can be performed from a PC, etc., via the USB interface.

PFC (Power Factor Control) function
The consumption current can be minimized with the PFC (input power factor control) function.
