Regenerative load function

biTRITON-B series products have a regenerative load function, which can feed back the energy of the device under test to the factory intranet for direct use, instead of dissipating it in the form of thermal energy. Its energy feedback conversion efficiency is as high as 95%, which can not only greatly reduce the electricity cost of users, but also avoid the use of air conditionersand other refrigeration systems and reduce noise.

Wide operating region, two-quadrant operation

The biTRITON-B series combines two devices in one: a power supply (source) and an electronic load (sink) with energy recovery capability. At the same time, this series provides up to 3 times wider output range, thus more applicationscan be tested using a single supply avoiding the need for multiple power supplies.

Seamless switch between sourcing and sinking

When conventional DC power supply and load switch between positive and negative currents, a short step will be generated at 0 A, resulting in discontinuous current commutation. biTRITON-B not only has two-quadrant working ability, but also has high-speed current switching ability, which can realize seamless connection between positive and negative current switching, effectively avoid voltage or current overshoot, and is widely used in motors, battery packs, BMS and energy storage systems test.

18 kW/3U high power density

The biTRITON-B series provides a high power density of 18 kW / 3U, with features such as accurate output, fast response, and low ripple noise.

User programmable sequence function

The biTRITON-B series provides users with user programmable sequence functions to simulate power interruptions, instantaneous drops, and simulating other voltage and current changes. A total of 10 sequence files, each file has 100 steps, supports loop and link to facilitate complex waveform output.

Battery charge / discharge function

Due to its unique bidirectional design, the biTRITON-B series has a charge/discharge test function, and is suitable for charge/discharge tests of various batteries and energy storage devices.

CV / CC priority

When power supply is connected to an inductive or capacitive load, it will cause voltage or current overshoot, which may trigger the protection of the device under test, or even cause the device under test to be damaged in severe cases. This series power supply provides CC priority and CV priority function, which forces the power supply to operate inCC or CV mode at the moment the output is turned on, effectively avoids the current or voltage overshoot resulted from capacitive or inductive load.

Master-slave parallel

biTRITON-B series power supply allows for master-slave parallel of up to 10 identical units.In parallel operation, slave units download parameters from master unit and current are shared automatically.

Optional analog programming and monitoring interface

In addition to front panel and remote interface control, there is a galvanically isolated analog interface terminal, located on the rear of the device. It offers analog inputs to set voltage, current, power from 0...100% through control voltages of 0 V...5 V. To monitor the output voltage and current, there are analog outputs with 0 V...5 V. Also, several inputs and outputs are available for controlling and monitoring the device status.

Digital interfaces

All models features two galvanically isolated digital interfaces by default, these are standard LAN and USB (optional RS485, GPIB, CAN nterface).USB, LAN and RS485 can be used to control and monitor the devices either with SCPI language commands or ModBus RTU protocol, while with GPIB only SCPI is supported, with CAN only CANopen is supported.

Photovoltaic cell array simulation function (optional)

biTRITON-B series built-in Sandia and EN50530 photovoltaic test regulations, users can also set photovoltaic cell I-V characteristic parameters (Voc, Isc, Vmp, Imp). Then turn on the power supply and output the I-V curve of the simulated solar cell array to the photovoltaic inverter to test its static MPPT efficiency.

Control software

biTRITON-B series provide a control software for Windows PCs, which can read test data, generate images, export reports, print reports, etc. It is convenient for customers to use.
