Sink Function
is built in power supplies, it is safe as able to lower
voltage quickly at cut-off output or even when lower voltage from
high voltage setting point. And, when make continuously burn-in
with short interval, it is possible to disconnect and change work
quickly after cut-off operation of output.
Conversely, when supply power to battery, condenser and so on
which is capacious load, it decrease reverse current from the load
to power supplies and avoids voltage depression by using
Anti-Sink
Function
at cut-off output or when lower setting voltage.
Note : It is impossible to stabilize by reverse current control. If the load is what reverse voltage
becomes higher than rated voltage (induced load, regenerative motor, etc.), please protect
the power supply by connecting dummy resister, reverse current protection diode and so on.
3 values for voltage and current are memorized
in addition to usual ones of preset.
It is very
useful for experiment to collect repeatedly data
and inspection of products.

LOCK
Either of 2 Modes can be selected and set,
“Full Lock” that locks all operation from the
front panel or “Normal Lock” that locks only
output ON /
OFF.
“Full Lock” is for the case that you like to
prevent securely any miss-operation, or
“Normal Lock” is for the case that you like
to prevent any miss-operation but can easily
stop in emergency. It is the useful function to
secure “Safe” you want.
(It is possible to emergency stop with the power
switch in every mode.)
Normal Lock
All switches are locked except the unlock-switch.
It is useful for the purpose to prevent miss-stop
at remote control or to prevent miss-operation
completely.
Knob to set output volt/current is locked. It is useful
for the purpose to prevent to change output value
by mistake at local control to make emergency stop
easily.
…
Dual tracking control, so that
output of plus and minus
are controlled at the same time
, is possible by
connecting the power supply so as to be able to
become plus and minus output at master-slave.
Multi-output can be configured in combination with
actions of local mode and of dual tracking.
Plus and minus output voltage and optional output
voltage set on a local slave are outputted in
synchronizing with ON of the master unit.
* As for connection, please refer to
“examples for operation applied” on Page 11.

*1 : R4K-36 series, R4K-80 series, RK-80 series, RK series, TB series and REK series. Detail catalog for each
model is available. Please contact nearby sales office.
*2 : Can be connected up to 16 pcs.
*3 : Only for slave-local. In case of slave remote control, exact same model of power supply need to be used. Also,
in case of slave-local, each output voltage and current can be set individually. In case of slave-remote, output
voltage and current can be set with one-control function which each slave unit follows the master unit setting.
In case -LUs1,-LEt or -LGob option is selected, only one unit of RKT series can be used.
Function to delay the OUTPUT ON / OFF time. It is possible to use in case single
unit of RKT series is used, and also when connecting several Matsusada power
supplies(*1) using master-slave connection terminal(*2) and output voltage / output
current are set individually, delay trigger function can be used.(*3)
