Next-generation model with high power and wide output range up 15kW in 19-inch, 3U rack

An increasing demand for EV and hybrid cars is accelerating the development of related equipment such as bidirectional inverters or motors in a wide variety models. Accompanied by such the development where simulation batteries are needed, our power supplies with PBR series have been well received. When compared to existing bidirectional power supplies, the product series is smaller and offers parallel operation that are capable of flexibly responding to diversifying needs of evaluation and testing. Moreover, the bidirectional power supplies of Matsusada Precision are attracting more expectations from solar power and renewable energy technologies in development.

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.

More Space Saving for Better Workplace

The PBR series product which is a perfectly compact sized DC power supply enables you to enhance work environment by saving the space. We have developed the smaller regeneration DC power supply for space saving aimed at installing other measuring tools, which makes effective use of the space at workplace.

Functions

Main Functions

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

Battery Simulator Function (Option)

-LAsoc Option can be selected to automatically vary the SOC value following the current integration of output and input.
In this function, if the current continue to be inputted to PBR, SOC will increase. On the other hand, if the current continue to be outputted from PBR, SOC will decrease. This option enables you to conduct more realistic battery simulations.

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 0.1 s to 3,600 s
  • For one program, the setting and saving are available for up to 1,024 steps and 16 patterns of programs at the maximum.
  • CV or CC mode can be set for each program
  • Repetition frequency: infinite, or 1 to 999

The product is provided with dedicated software to allow a series of configuration using PC. Accordingly, you can use the product with different applications depending on the specification.

CV or CC Priority Setting Function

CV (constant voltage) priority or CC (constant current) priority mode can be selected and set.
As is the case with diodes, the load tends to suddenly change the resistance at certain points, and if the device is started in CV mode, the current will result in overshoot.
With 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 diode.

CV priority mode CV priority mode
CC priority mode CC priority mode

* Overshoot is less likely to occur if the value is set to the lowest in the range where the CC state can keep, without releasing the voltage setting even in CC priority mode.

Other functions

Supports Expansion with MASTER/SLAVE Control

Capable of covering a wide output range with parallel connections of up to 10 units in total.

  • Expandable to a total of 10 MASTER and SLAVE units combined.
  • 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: Always use cables with uniform thickness and length over the full length for output cables connected to the load from these devices.

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

With this function, you can readily perform not only reading sequence files which are optionally created by users also collecting operating logs.

Software as Image
Sequence Setting Input or Output software

The software is solely used for reading the operating log, and can open the log file outputted from the main unit.

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

display with USB memory

Besides, 16 patterns of sequence as well as 100 patterns of I-V curve is loaded from USB memory. The operating log is also outputted to USB memory as well.

Two-mode Lock Function

Can be set by choosing from two setting modes: one is “Full LOCK” to lock all front panel operation, and the other is “Normal LOCK” to lock everything except the OUTPUT ON/OFF switch.

The function is so user-friendly that the “Full LOCK” mode is p rovided to ensure the prevention of erroneous operation, and the "Normal LOCK" function facilitates the emergency stop w hile preventing erroneous operation.

Emergency stop operation using the POWER ON or OFF switch is possible in either mode.

Full LOCK

Except for LOCK release, all switches, 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 OUTPUT ON/OFF, the touch panel, and encoder are locked. It is further effective to prevent the erroneous changes of output values during the remote control and to facilitate emergency stops.

Normal LOCK function

Internal Resistance Variation Function (during CV mode)

Internal resistance is set to an arbitrary value, and a voltage drop is caused by the load current. 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/Sink Current Prevention Function

The power supplies are equipped with a sink current function, making it possible to reduce the voltage quickly when turning off the output or when decreasing the voltage from a high setting value, thereby improving the safety of operation.
In addition, with the sink current function, quick connections can be made after the output is turned OFF, and workpieces can be changed when conducting a series of burn-in tests.

Conversely, when supplying power to loads with capacities such as batteries and capacitors, the sink current prevention function can be used to reduce reverse current flowing from the load side to the power supply side and prevent a drop in load voltage when the output is off or when decreasing the set voltage.

Sink Current
Reverse Current Prevention

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.).

Status output

status output

The status output is provided by open collector. It has a floating common terminal which is used for all the status outputs. Use Breakdown voltage 30 V with less than SINK current 5 mA

Output Range

The regeneration has the lower limit of the voltage or current. Contact a sales representative for further information.
