Bidirectional current, seamless switch between source and load

TRBB series DC source can not only provide external power, but also absorb power, and return electric energy to the grid cleanly. TRBB series bidirectional power supply can be converted continuously seamlessly between the output and absorbed current, effectively avoiding voltage or current overshoot. It is widely used in power battery, UPS, battery protection board and other energy storage equipment testing.

Wide range of output design

TRBB series bidirectional DC power supply adopts a wide range design. A single power supply can output a wider range of voltage and under the rated output power, satisfying engineers' test application current scenarios for products of various voltage / current levels, and greatly reducing purchase cost and space occupancy in laboratory or automated test systems.

CC&CV priority function

TRBB series has the function of setting voltage loop feedback circuit priority or current loop feedback circuit priority, it can adopt the optimal working mode for testing according to the characteristics of DUT, so as to better protect DUT. TRBB series has the function of setting circuit priority or current loop feedback circuit priority, it can voltage loop feedback adopt the optimal working mode for testing according to the characteristics of DUT, so as to better protect DUT. As shown in Figure 1, when need to reduce voltage overshoot during testing, the voltage priority mode should be used in order to obtain a fast and smooth rising voltage. As shown in Figure 2, when need to reduce current overshoot during testing, the current priority mode should be used to obtain a fast and smooth rising current.

Master/slave design, convenient for power expansion

TRBB can be used independently or in master/slave parallel operation. It has built-in master/slave mode, and the Max. power can be expanded to 180kW. It adopts a unique current sharing design to ensure each module shares the load equally and ensure the consistency of product use.

Fast dynamic response

TRBB series can achieve seamless switch between current output and current sink. Take TRBB-500ｰ120ｰ183 for example. The switch time from source 120A to sink 120A is less than 2ms as below figure.
