Autoranging with 3 times the voltage and Current available for flexible operation

PRKT series is DC power supply equipped with a turbo function, enabling a wide range of voltage/current three times higher than previous DC power supplies with approximately the same rated output power.

The PRKT series all allows flexible voltage and current output within its rated power, resulting user not to require to search for power supply with unnecessary wider rated voltage and current. Thus single PRKT unit can be used for much wider user application.

Not only its a wide range of output, but the general performance of the power supply is pursued to achieve overwhelming quality, providing power factor correction circuit with 0.99 power factor, color display panel having excellent visibility, and adoption of speedy and excellent precision rotary encoder.

Front Panel USB Port Available

USB memory connected to the USB port on the front panel enables a data logging function and built-in sequence program input/output function.

Matsusada Precision 2 application operations with the front USB terminal

No data logger or no always connected a computer required

Shortening time of wiring and preparation, Suited for cycle tests in areas where computers are prohibited.

•Features:Built-in data logging

Data logging captures the output data at the fastest interval of 0.1 seconds by inserting the USB memory stick. Also, with the dedicated software MLV, the log data is available in CSV format to output.

•Use in places where you cannot always connect a computer

With the dedicated software MSS, you can save the sequence program data to the USB memory and load it from the front USB port. Thus, the program operation is available by the power supply only.

Application Software

Two dedicated application software packages are included as standard accessories to maximize the use of the front panel USB port.

(1) Sequence function: MSS (Matsusada Sequence Software)

Easy to use for beginners

With MSS, the dedicated software, you can create sequence data using a PC. The software makes it easier and more convenient to create sequence data. The created sequence data can be saved to USB memory, and up to 1,024 steps of the sequence program can be loaded.

(2) Operation log display: MLV (Matsusada Log Viewer)

Instant graphing of operation logs

Operation log display function: MLV, the dedicated software can read and graph the operation log. Logging to USB memory is available not only during the sequence operation as described in (1) above, but also during the local/external control.

Easy editing of operation logs

MLV can select items you need and save them in CSV format, so you can also edit the data in spreadsheet software with no problem.

Constant Power Control Function (CP mode)

In addition to Constant Voltage control (CV mode) and Constant Current control (CC mode), Constant Power control (CP mode) is provided.

With CP mode, a constant power supply is provided depending on loads, such as resistors (heaters) whose resistance changes with temperature. It is available without monitoring voltage/current or attaching external control devices (temperature regulators).

CV/CC Priority Setting Function

CV (Constant Voltage) priority/CC (Constant Current) priority modes can be selected and set. As is the case with diodes, a load tends to suddenly change the resistance at certain points. When the device is started in CV mode, the current will be momentary overshot. Using the PRKT series, the occurrence of overshoot can be suppressed by selecting CC priority mode. The function can reduce the risk of damaging expensive loads such as high-power laser diodes.

CV priority mode
CV priority mode
CC priority mode
Always starts in CC

* Overshoot is less likely to occur as the CC value is set to the lowest in the range where the CC state can keep not by releasing the voltage setting even in the CC priority mode.

Internal Resistance Variation Function (during CV mode)

A value set to the causes a voltage drop when the load current flows. Batteries, Photovoltaic cells, and Fuel cells can be simulated. (The setting range of the internal resistance value is from 0 Ω to the rated voltage/rated current.)

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

Note: Reverse current cannot be controlled and stabilized. Connect a dummy resistor or reverse current prevention diode when load of the reverse voltage is equal to or higher than the rated voltage (inductive loads, regenerative motors, etc.).

Supports Expansion with MASTER/SLAVE Control

Wide range output with parallel connections up to four units (20 kW).

  • Expandable to a total of four MASTER and SLAVE units (20 kW).
  • During MASTER/SLAVE connections, values of output voltage/current for the overall unit are displayed on the output voltage/current meter of the MASTER.
    (Individual output values are not displayed on the output voltage/current meter of each SLAVE.)
    Note: Make sure to use the same length of all the cables to connect to each load from the main unit.

*Dedicated cable for master-slave connection is available.
We offer the set of a parallel control cable and a cable with attached shared terminal.

Two-mode Lock Function

The locking is selectable from two setting modes: one is “Full LOCK” to lock all front panel operation, and the other is “Normal LOCK” to lock everything except for ON/OFF switch.

Preset Memory Function

With the preset memory function, the preset values are automatically saved when turning power off. Furthermore, up to three different voltage, current, and power settings are also memorized respectively.

External Analog Control

Easy connection to control devices thanks to independent external analog control of the output!
The control signal is isolated from output. So, when you operate the analog control with the control device or series operation, floating of control signal is no longer required.

  • External output ON/OFF
    The output can be turned ON/OFF by the external relay or TTL signal.
    The logic of the signal can be selected by 5 V input.

  • Remote sensing
    It ensures the prevention of stability deterioration caused by the voltage drop (VO-VL) by the resistance (R) of the output wire and the contact resistance (up to 0.5 V).

  • Remote/Local mode setting
    Voltage, Current, Power, Overvoltage protection, Overcurrent protection and Overpower protection, can be switched by relay or TTL signal.

  • Output monitor(Voltage, Current)

  • Output control (Voltage/Current/Power/Overvoltage protection/Overcurrent protection/Overpower protection)
    Select only the functions you need ! Prepare the lowest command voltage !
    Up to three settings are selectable in voltage, current, power, OVP, OCP, and OPP. You only need to have the command voltage for the items by external control, which can help reduce costs and manhours for design.
    (For items not selected, the main unit setting values will be reflected.)

  • Status output
