1-3. Features
■
Flexible range Output
Capable of wide-range voltage and current setting within the rated
power range to cover the ranges of four models of our existing PS
power supply units.
■
Constant-Power Control
Newly provides constant-power (CP) control in addition to
constant-voltage (CV) and constant-current (CC) controls.
■
Power Factor Correction Circuit
A built-in power factor correction circuit ensures compatibility to a
wide AC input voltage range from AC100V to 240V without the
need of switching. It also suppresses harmonic current.
■
Two-Output Model (PSF-400L2)
Equipped with two 400W output channels for a wide variety of
applications.
■
Rotary Panel Operation Unit
The panel operation unit may be rotated by 90 degrees for
easy-to-see monitoring in either horizontal or vertical installation.
■
Off Timer Function
Turns off output automatically after a lapse of preset time in order to
prevent
“a failure to turn off output” or “over-charging” even in the
case where the user does any other work without turning it off.
■
Sequence (SEQ) Function
Executes data read from a Personal computer through the optional
interface board on the panel operation unit. Two operation modes
are available: Manual mode (for execution while checking the step
details), and automatic mode (for automatic execution of steps).
(99 steps, 999 cycles)
■
Delay (DLY) Function: PSF-400L2 Only
Capable of setting the time of changing the output actually after
turning it on (or off) between the channels A and B.
■
Tracking Function: PSF-400L2 Only
The set value of the channel B is made equal to that of the channel
A when the tracking function is activated. Hereafter, both
channels change synchronously.
■
Protective Functions
Has internally fixed protective functions, which are OVP, OCP and
OHP. Also has OVP and OCP functions, which may be set on the
panel operation unit.
■
Preset Functions (Three Points)
Pressing a preset key directly selects a preset value, which is set in
advance.
