Wide Range Output Area Voltage / Current 4 Quadrants Operation
BP series can output in four quadrants and is capable of handling two directions of current, which are source (supply) and sink (absorption) current.
From devices that generate back electromotive force such as solenoids, capacitive load such as electrolytic capacitor, and even to piezoelectric material charged with electromotive force and power sources and batteries such as fuel cells, you can drive the devices and systems that cannot be driven with generic DC power supply.

Wide range

Depending on the limiter setting, the output range can be shifted to - 5 V to + 115 V and -115 V to + 5 V (Output current range changes)

High Voltage / Large Current / Wide Range, Constant Current Operation
Output voltage is + / - 60 V covering the range required in testing vehicle electrical components. Also BP series have high current necessary for large parts, high speed required in driving actuators, and constant current operation effective in driving low impedance solenoids.
With such enriched specification satisfying all such requirements, BP series responds to the needs in development and test of devices.
With the lineup from + / -10 A to + / -100 A, BP will respond a variety of application.

Function Brings Usability and Efficiency
Sequence Function
BP series has a built-in sequential signal source. For example, by programming a series of voltage change pattern used in voltage fluctuation test on electrical and electronic components, the test can be done in a single operation since the output changes in order according to the procedure.

Number of sequences : 1 sequence for each of the CV mode and CC mode
Number of steps : 1 to 255 (within 1 sequence)
Step time : 0.1 ms to 999.9999s (resolution 0.1 ms)
Parameters : DC voltage, superimposed AC voltage, frequency and
Jump count : 1 to 999, or continuous
Sequence control : Start, Stops, Hold, Branch

Various Output Patterns Using Sequence Functions

The dedicated software allows user to edit the complicated pattern easily

In addition to set at the hardware, The application software is available to edit the sequence pattern. This software will included in bundled set.



Response Calibration Function
Transient response for load with complicated impedance characteristic such as electromagnetic components with inductance (coil component) or capacitance (capacitor component) differs among loads. BP series has a response calibration function that allows users to individually optimize transient response characteristic in square wave output or sudden output change.



Voltage Limiter / Current Limiter
BP series have the capability to set each of the maximum voltage and current with + and - independently.
When shifting the output voltage range, output voltage limiter is used.
