DC Power Supplies R4K-80 Series

Ultra Slim Sophisticated Bench-top Power Supplies

R4K-80 series are higher performance DC variable power supplies. 4-digit digital meter and high resolution D/A, A/D converters are added newly for more precise setting and reading. Needless to say, the innovative compact size, variable range feature and high operability are remaining same as conventional RK-80 series. R4K-80 series is the best suitable DC power supply for a variety of applications from laboratory experiment to line productions.

Delay Trigger Function

In case -LUs1,-LGob or -LEt option is selected, only one unit of R4K-80 series can be used.

Function to delay the OUTPUT ON/OFF time. It is possible to use in case single unit of R4K-36 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)

*1: R4K-36 series, RK-80 series, RK series and REK series. Detail catalog for each model is available. Please contact nearby sales office.
*2: Can be connected up to 16 units.
*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.

Two Mode Lock Function

Function to select two different lock functions for two different purpose."Full Lock" locks all the function on front panel, and "Normal Lock" locks all the function except for ON/OFF. "Full Lock" mode shall be good in case mis-operation have to be completely avoi ded, 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.)

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.

Change length of CO-M cable to 0.5-meter long or 0.15-meter long.

-LHHigher isolation voltage

This option make the isolation voltage to be ±1 kV, which enable extended capability of series operation.

*1 These options cannot be selected together. Only one of each can be selected.
*2 If you select these options, standard digital interface will not be equipped. Also, please see the CO series catalog for detail of function of digital interface function.
*3 Please consider the location of usage. High humidity environment can be the cause of failure and corrosion.
*4 Master/slave function is not available.

-LDePulse Ramp Sequence

Below output control, between A to D is available

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.

B. RAMP SEQUENCE
This function controls the ramping up and down the voltage and current to the set value (or from set voltage and current value to 0V/0A). 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].

C. COMBINATION OFPULSE and RAMPSEQUENCE
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.

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.
(Master follow function cannot be used with -LUs1 or -LEt option.)

Series Operation · Parallel Operation

R4K-80 power supply of same model number can be connected in series or parallel to increase output voltage or current.
In that case, local control or the control in the digital master slave is recommended.
Because the common of the outside input/output control connector (TB1) is connected to the positive output, please do not connect common more than two.

Accessory Kit

Various accessories are available for convenient use of the unit.

TECHNICAL NOTE

Connection Operation

Connection of load

  • Please use a short lead wire that is sufficiently thick for the connection.
  • Please use PVC electric cable (105°C ) that can fully to lerate the voltage used. It is necessary to consider current capacity, length limit of output wire by sensing (0.5V/lead) and so on for wiring with load. Please refer to the following diagram to determine the thickness of cable.

Definition of specifications

Applicable scope of specifications
"F.S x catalog value(*)" is applied for ripple, stability, requlations and temperature coefficient, and "value if F.S x 0.5%(*)" is applied for high-voltage output linearity, moniter linearity and display linearity, both in the range of 10% to 100% of maximum rating output.

Ripple
Indication is in rms that includes high-frequency noise.

Preset
Preset value does not show the actual output status accurately. If you need an accurate setting, conduct actual output without load and set a voltage. Also for setting current, conduct output after shorting the output terminal and gradually raise current before setting at a desired value.
