How to compact

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 such a sufficient cooling function to maximize the high performance.

Air-through Circuit Block Technology

Following the structure review of the 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 the 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.

How to compact

Matsusada Precision 2 application operations with the front USB terminal

No need for always connected to a computer.
Programmable output sequences and operation log acquisition are available in places where a computer cannot be permanently installed!

You can create sequence program data using not only the main unit but also a computer with the dedicated software. Using the dedicated software, the created sequence program data can be saved to an USB memory and loaded from the front USB port.

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

Easy to use for beginners
MSS allows you to create sequence program data using the main unit or a computer with the dedicated software (MSS).
The software makes it easier and more convenient to create sequence program data. The created sequence program data can be saved to USB memory, and up to 1,024 steps of the sequence program can be loaded.

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. In the PRT/PRTM 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.

CV priority mode Matsusada Precision CV priority mode
CC priority mode Matsusada Precision CC priority mode

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

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.)

Matsusada Precision Internal Resistance Variation Function (in CV mode)

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.

Sink current prevention

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.

Matsusada Precision Sink current prevention

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 operation, 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.

Emergency stop operation using the POWER ON/OFF switch is available in either mode.

Full LOCK

Matsusada Precision Full LOCK

All switches including the touch panel and encoder are locked except LOCK release. It is further effective to prevent the erroneous stop during the remote control and to completely avoid erroneous operation.

Normal LOCK

Matsusada Precision Normal LOCK

Switches the touch panel, and encoder are locked other than ON/OFF. It is further effective to prevent the erroneous changes of output values during the local control and to facilitate emergency stops.

Unlocking password function New function

In this function, to cancel the two-mode lock function, input a 4-digit PIN code. (Enable/Disable is selectable.)

With the function, the following troubles can be prevented.

  • As the output was accidentally turned off during a long aging test, all the data was deleted.
  • Output condition was changed due to erroneous operation during burn-in tests of the shipping inspection line, resulting in damage of the test objects.
