3. Turn on the switching mode.
Press the SW ON key.
The SW ON key illuminates, and the switching mode is enabled.
• Setting the switching function using frequency and duty cycle
4. Select switching frequency and duty cycle.
Press the FREQ/DUTY key.
The FREQ/DUTY key illuminates.
Switching frequency (FREQ) or duty cycle (DUTY) is highlighted alter-
nately each time you press FREQ/DUTY.
Highlight the one you wish to set.
5. Set the switching frequency and duty cycle.
While viewing the display, turn the rotary knob to set the value.
You can press the rotary knob to switch between coarse adjustment and fine
adjustment.
• You can set the switching frequency in the range of 1 Hz to 20 kHz, but if the fre-
quency is set high, limitation is placed on the upper limit of the duty cycle. The
resolution (Hz and kHz) switches automatically.
• Setting the switching function using time
4. Select the switching time.
Press the Th/TL (SHIFT+FREQ/DUTY) key.
The Th/TL key illuminates.
The high side (Th) and the low side (TL) of the switching time is high-
lighted alternately each time you press Th/TL (SHIFT+FREQ/DUTY).
Highlight the one you wish to set.
5.
Set the switching time.
While viewing the display, turn the rotary knob to set the switching time on the
high side and low side.
• The settings for the switching operation can be changed even when the load is
turned on.
■ Operation when the response speed is changed
You can change the response speed in CC mode (CC+CV mode) and CR mode
(CR+CV mode).
In some cases, the wire inductance increases and a large voltage drop occurs due to
changes in the current or the phase lag of the current may cause instability in the
PLZ-4W control inducing oscillation.
In such case, you can decrease the response speed to assure stable operation.
• For details, see section 5.15, "Response Speed."
