Lock voltage and current setting dial.
This mode is good for purpose to avoid
changing output setting by mistake or
when easy emergency stop is required.
Lock all the function other than reset
lock mode. This mode is good for
purpose to avoid mis-operation
complelely.
Function to select two different lock modes for two different
purposes."Full Lock" locks all the functions on front panel, and
"Normal Lock" locks all the functions except for ON/OFF switch. "Full
Lock" mode shall be good in case mis-operation have to be
completely avoided, and "Normal Lock" mode shall be good in case
to avoid mis-operation but secure the way for emergency stop of
power supply. You can select the best mode according to your level
of "Security".
(In both modes, emergency stop is possible with Power Switch.)
Function to output ON/OFF of total 32 units from one master
unit.(when Master/Slave)
*
It is possible to delay the ON/OFF time,
and simultaneous ON/OFF setting is possible as well. Ideal
function for application which requires to turn on power one by
one or time lag.
Dual tracking control, which enables both positive and negative
outputs simultaneously in master slave operation, is possible. Multi
outputs and various versatile operations are also possible by
combining above dual tracking control and slave local mode.
Positive and negative V, -V) of dual tracking control and
set output voltage of slave local mode can be output
simultaneously by turning on the master unit.
*
Please refer to P.10 for detail connection.
Function to memorize 3 different voltage and current settings in
addition to standard preset function.
No need to adjust the output when different setting, and
convenient function for production inspection process or testing
which require frequent data taking.

<NOTE> It is not possible to stabilize the output by controlling back current. In case of load which
has inverse voltage or over rated voltage, such as inductive load or regenerative motor, protect the
power supply by adding dummy resister or diode to prevent back current.

REK series features
function to sink current
, and enable to decrease
the voltage quickly when turning off the output or when control the
voltage down, which increase the safety of operation. In case that
continuous aging test in short interval, quick voltage fall time increase
the efficiency of process. On the contrary by using
sink current
prevention
function, it is possible to prevent voltage drop on the load by
decreasing the current flow from load to power supply when turning off
the power supply or when decrease the output voltage.
