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.

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

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

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

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

Output Expansion Up to 150kW with Master/Slave Control

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

[Sample Connection]

Master/Slave control cables are also available as options. go to Master/Slave control cable

• 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.

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.

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.

Full LOCK

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.

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.)

Remote Control

Using the connector in TB1 attached on the back of the unit, the status outputs are available by open collector.
