Adopting Air-through Circuit Blocking Technology

With the rise of EVs and hybrid cars, various devices related to bidirectional inverters and motors are being developed. Our PBR series, as a power supply simulating batteries required to develop those devices, is playing an active role.
When compared to existing bidirectional power supplies, PBR series that is smaller and parallel operation available allows you to flexibly cope with varying needs for evaluation and testing. Moreover, the bidirectional power supplies developed by Matsusada Precision are expected to contribute to technology development such as solar power and renewable energy.

Features and benefits

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 Blocking Technology
Following the structure review of the circuit blocking, the product has been made smaller, and we also have put more focus on the improvement of block arrangement contributing to the 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.

Battery Simulator Function (Standard)

In the function, the simulation of I-V curve which is a fundamental feature of battery is provided. The voltage or current value is set at 1001 within the rated voltage or current of the PBR unit. In order to use this function, setting and loading in the PC application attached as standard are needed. Additionally, as many as 100 graph patterns (of I-V curve) are loaded to the PBR unit through this function.

Battery Simulator Function

SOC Automated variable Function (Option)

(1) Using -LAsoc Option, you can automatically change the graph patterns which have been previously created according to the power running or regenerative operation. For power running, the SOC will decrease, and on the other hand, for regeneration, the SOC will increase.

The integrated current is automatically calculated respectively to the change the graph patterns accordingly.

Sequence Function

The function is available only for power running while it is not applied to the regeneration.

In terms of programmable sequence functions of step time, step amplitude, ramp, CV/CC mode, sequence end setting, step jump, and jump count, the sequence control makes such parameter operations much easier by only using the front panel operation.
As this option enables to generate optional waveforms, you can use a great variety of applications including testing evaluation, and verification.

  • Step setting time 0.0 s to 3,600.0 s
  • For one program, a maximum of 1,024 steps can be configured and stored.
  • CV/CC mode can be set for each program.
  • Repetition frequency: infinity, or 1 to 999

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 momentary overshot.
Using the PBR 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 CC priority mode

* 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.

Other functions

  • Expandable to a total of 10 Master and Slave units.
  • In Master/Slave connection, the values of output voltage/current for the whole unit are shown on the output voltage/current meter of the Master. (However, each Slave unit does not display the individual output values on the output voltage/current meter.)

Note: Make sure to use the same length of all the cables to connect between each load and the main unit.

Sequence Setting Input or Output and Operation Log Output via Front USB Terminal

With this function, you can readily perform not only reading the sequence settings arbitrarily created but also collecting operating logs.

Operating log Image
Sequence Setting Input or Output software

The attached software can read the log file output from the main unit and shows the data in a graph.

The information on operating log is shown on display as of operation time, CC/CV mode, output value (of voltage, current or power), status, and error data.

display with USB memory

In the function, 1,024 steps of sequence programs as well as 100 patterns of the I-V curve are loaded from a USB memory. The operating log is also outputted to USB memory.

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 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 or OFF switch is possible in either mode.


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

Full LOCK function
Normal LOCK

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

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.)
