Functions

Sink Current Suppression

When supplying power to loads with capacities like batteries and capacitors, the sink current suppression is used to reduce the reverse current flowing from the load to the unit in order to prevent a voltage drop on the load as the output is OFF or the set voltage is lowered.

Sink Current Suppression

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.

Multi Setting Function

Function to memorize three 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.

Multi Setting Function
Multi Setting Function

Two Mode Lock Function

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.)

Full LOCK

Full LOCK

Lock all the function other than reset lock mode. This mode is good for purpose. to avoid mis-operation completely

Normal LOCK

Normal LOCK

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.

Delay Trigger Function

In case -LUs1, -LEt or -LGob option is selected, only one unit of REK/REKJ series can be used.

Function to delay the OUTPUT ON/OFF time. It is possible to use in case single unit of REK/REKJ series is used, and also when connecting several Matsusada Precision power supplies *1 using master-slave connection terminal*2 and output voltage/output current are set individually, delay trigger function can be used.*3

  1. R4K-36 series, R4K-80 series, RK-80 series, RK series, TB series and RKT series.
    Detail datasheet for each model is available. Please contact nearby sales office.
  2. Can be connected up to 16 pieces.
  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.
Delay Trigger Function

* t1 to T8 can be set in the range 0.0 to 99.9 s.

Dual Tracking, Multiple Outputs

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 output (+V, -V) of dual tracking control and set output voltage of slave local mode can be output simultaneously by turning on the master unit.

-LDe

Pulse/Ramp Sequence, Master Follow Function

A. Pulse sequence

Using the stored voltage and current setting in each memory of a, b and c and multi set function, sequence operation is possible. The setting of repetition to say nothing of a continuous driving can be set. Various different operations, such as repetition of memory a and b or b ,c and off, are possible by setting the set time of memory a, b, c, and/or off to be 0.0. Thus, it makes this model suitable for evaluation test or other applications.

A. Pulse Sequence

ta, tb, tc and toff can be set with range 0.0, 1.0s to 99.9 h respectively.

B. Ramp

This function controls the ramping up and down the voltage and current to the set value (or from set voltage and current value to 0 V/0 A). It is convenient to increase (decrease) the voltage and current value slowly.

  • The Ramp sequence can be selected from [both set voltage and current], [only set voltage], and [only set current].
  • Master follow function cannot be used with -LGob, -LUs1, and -LEt option.
Ramp

t1 and t2 can be set with range 0 to 999 s respectively.

C. Combination of pulse and ramp sequence

Features of pulse sequence operation and ramp sequence operation can be combined for more convenient operation. In addition, by adding multi set function, sequence operation can be operated using stored voltage and current settings in each memory. The setting of repetition to say nothing of a continuous driving can be set. For example it is possible to slowly ramp up and down the voltage and current to the three different settings, and so, it is useful on various scenes.

Combination of Pulse and Ramp Sequence

t1, t2, t3 and t4 can be set with range 0 to 999 s respectively.
ta, tb, tc and toff can be set with range 0.0 s, 1.0 s to 99.9 h respectively.

D. Master follow

When the pulse sequence operation and the ramp work master/slave, the output signal to the slave unit is transmitted. The slave unit can be output in an output status different from the master unit.

  • The Ramp sequence can be selected from [both set voltage and current], [only set voltage], and [only set current].
  • The master follow function is only available with the standard interface.
Master follow

Note: The operation accuracy of the timer when sequencing is 0.5%. Be careful when you use it by the long-term running operation.
