What is a bidirectional power supply ?
A bidirectional power supply (regenerative DC power supply) is a power supply that functions as both a DC power supply and a DC electronic load in a single unit and regenerates power to the AC power source side during the electronic load operation. It is also known as a regenerative power supply, regenerative electronic load, or bidirectional power supply. The power supply is available in various applications, including evaluating inverters, DC-DC converters, motors, and other tests without switching connections.
We recognize the importance of renewable energy for sustainable development, diversification of energy supply, and preservation of the environment, considering rapidly changing international situations. To address critical issues such as the energy crisis and climate change, carbon neutral and carbon offset initiatives to reduce greenhouse gas emissions are underway. The use of renewable energy sources such as solar power, wind power, and green hydrogen is also promoted. The development and spread of environmentally friendly technologies such as electrified electric vehicles with the power train system, household storage batteries, and fuel cells have been accelerated.
In response to the social conditions, the PBR series of regenerative DC power supplies regenerates power to use energy effectively, contributing to developing and evaluating inverters, converters, and other devices.

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. In the PBR 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.
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.)
Preset Memory Function
The series comes with the preset memory function by which the preset values can be automatically saved at power off.
Additionally, the storage of up to three respective setting values of the output voltage/current/power is available.
Secure Analog remote control
The external analog remote control of voltage/current/power is isolated from the output of the power supply as standard.
When controlling/monitoring multiple power supplies, you can use the product more securely as the external analog input/output control has a chassis (ground) potential.
External Analog Remote Control
- External output ON/OFF
-
The output can be turned ON/OFF by the external relay or TTL signal. The logic of the signal can be selected by 5 V input.

Residual voltage detection LED
Use for checking residual voltage
The LED on the rear panel blinks when there is voltage remaining on the DC input/output terminals in output or at output off (only in the power running operation).
It is useful for reference to check if the voltage remains. Be sure to check the voltage before the operation of the unit.
Expandable to 150kW with Master/Slave Control
Easy expansion of your choice up to 150kW
Within the same series, you can increase the power using the shared cable and parallel control cable (LAN cable).
Even if you want to change testing items or targets, you have only to add the necessary amount.
("Master/Slave Control Cable", a Matsusada Precision original set of pre-processed share cable and parallel control cable is available.)
Two-mode Lock Function
The lock function is available with two modes: "Full" to lock all front panel operations and "Normal" to lock all operations except the ON/OFF switch.
With the “full” lock mode, all operations on the front panel are locked to prevent erroneous operations. Meanwhile, the “normal” lock mode can lock all operations except the ON/OFF switch in which the emergency stop is enabled. It is a useful function that ensures what you consider to be “safety”. This is a convenient function that ensures what customers consider to be "safety".
