    More Space Saving for Better Workplace | PRT series | DC power supply Rackmount | Matsusada Precision

    State-of-the-art semiconductor
    In order to minimize the heat generation itself inside the power supply, we adopted the latest device including semiconductor elements of high efficiency via thorough examination. This enables the product to provide a sufficient cooling function to maximize high performance.

    Air-through circuit block technology
    With the improvement of the air-through circuit block, the product has been made smaller, and we also have put more focus on the improvement of block arrangement contributing to excellent space efficiency by extremely reducing the dead space. Consequently, we achieved the significant development of high-density mounting technology. While extra spaces inside the device had been required to release the heat so far, we successfully made the product even smaller to ensure the total amount of height of a mere 133 mm.

CV/CC Priority Setting Function

CV (constant voltage) priority/CC (constant current) priority mode 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 momentarily overshot. In the PRT series, select the CC priority mode to suppress the occurrence of overshoot. The function can reduce the risk of damaging expensive loads such as high-power laser diodes.

* In the CC priority mode, do not by releasing the voltage setting and setting the CC value to the lowest within the range where the CC state can be maintained.

CV/CC Priority Setting Function | PRT series | Rack Mount DC Power Supplies | Matsusada Precision

Internal Resistance Variation Function (in CV mode)

Set the internal resistance to any value to generate 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.)

CV mode | PRT series | Rack Mount DC Power Supplies | Matsusada Precision

Preset Memory Function

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

Remote Control Software (Additional products): DigiCon series

DigiCon is an application software that remotely controls Matsusada Precision's DC power supplies connected via LAN or USB.
The software can control multiple power supplies simultaneously or individually.

  • Power control for PRKT, PRT/PRTM, PBR/PBRM series
  • Full remote control available

  • Linkage to digital multimeters, data loggers, and thermostatic chambers is possible.
  • Easy operation with Graphical User Interface (GUI)
  • Automatic Test Equipment (ATE)s can be built without programming knowledge.
  • Real-time logging, graphing, and data storage

Link with digital multimeters, data loggers, and thermostatic chambers is possible.

Program transitions can be made in response to external conditions by linking with measuring instruments such as digital multimeters and data loggers, as well as thermostatic chambers.
This advanced function allows the program to transition to the next step when the end condition of the instrument is met without waiting for a set time, or to safely terminate the program if a problem occurs during operation.

Link with digital multimeters, data loggers, and thermostatic chambers is possible. | PRT series | Bidirectional (Regenerative) DC Power supply | Matsusada Precision

Easy operation enables speedy construction of Automatic Test Equipment (ATE)

Graphical user interface, including graphical display of set values, allows easy operation.
Automatic Test Equipment (ATE) and inspection systems can be built without programming knowledge.
It can be used in many fields and applications, such as long-term reliability testing of electronic equipment and devices in the automotive, home appliance, and medical fields.

Sink current prevention function

The function is suitable for supplying power to loads with capacities like batteries and capacitors. It reduces 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 prevention function | PRT series | Rack Mount DC Power Supplies | Matsusada Precision

Note: Reverse current cannot be controlled and stabilized. In order to protect the power supply unit, connect a dummy resistor or reverse current prevention diode if the load of the reverse voltage is equal to or higher than the rated voltage (inductive loads, regenerative motors, etc.).

Two-mode Lock Function

The locking is selectable from two setting modes: One is "Full LOCK" to lock all front panel operations, and the other is "Normal LOCK" to lock all operations except the ON/OFF switch.
The function is so user-friendly that the "Full LOCK" mode is provided to ensure the prevention of erroneous operation, and the "Normal LOCK" function facilitates the emergency stop while preventing erroneous operation. Emergency stop operation using the POWER ON/OFF switch is possible in either mode.
