1.3 Applications
EC1000SA 1-3
Enables AC-superimposed DC output
When in the AC+DC mode, an AC wave (sine wave, square wave, or arbitrary waveform) can be
superimposed on the DC output.
Also supports capacitor input load (up to crest factor 4 is supported)
Enables peak current output of up to four times as large as the maximum output current (RMS value).
Can be used as an external input amplifier
When “in external” is selected, an internal signal source can be added to the external signal
input.
Sequence function
When using an internal signal source, output parameters (output voltage, output frequency, etc.) can be
successively and rapidly changed or swept. In addition, output of specified patterns can be provided
by program in advance.
Output current limiter function, voltage and frequency upper limit and lower limit
setting functions
The output current is limited within the maximum values that have been set independently for positive
and negative. As for the output voltage and the output frequency, their setting ranges can be
adjustable.
USB interface (USBTMC), RS232 interface are standard equipped
USB interface and RS232 interface are provided for external control, such as from a personal
computer.
Output outlets equipped on front panel (universal type)
Various types of power plugs from around the world can be connected.
Supports worldwide range input power line voltages
Input power factor control (PFC) function for 90 V AC to 250 V AC helps minimize input power line
current.
