TBD-series Programmable Bidirectional DC Power Supply
TBD-series is a bidirectional programmable DC power supply that integrates a DC power supply and a regenerative load. It can realize the SOURCE function to provide energy to the load, and also has the SINK function to absorb load energy and feed back to the grid to achieve dual-quadrant operation. TBD-Series has a maximum voltage of 2250V and supports multiple parallel machines to achieve power expansion. It is widely used in automotive electronics, power batteries, photovoltaics, energy storage testing and other fields. |

Type Recommendation
Energy flows in both directions, fast switching
TBD-Series integrates source and load into one design, achieving highspeed source and load current mode conversion, thereby quickly switching between output current and absorption current, effectively avoiding voltage or current overshoot.
Oscilloscope mode displays the simulated curve of the photovoltaic array in real time
TBD-Series power supply has built-in EN50530, Sandia and other standard SAS models, which can simulate the IV/PV curve of the solar cell array. After the user sets the parameters, curve can be generated and output internally to test the static and dynamic maximum power tracking performance of the inverter. At the same time, this mode has an oscilloscope function, which can display the IV/PV curve on the interface and display the current working coordinate point in real time,
which is simple and intuitive.
It can simulate the charge and discharge characteristics of various types of batteries. Common power battery characteristic curves can be directly called and battery characteristic curves can also be customized.
Capable of charging and discharging the battery and testing its capacity, cycle life and power characteristics.
Realize various standard curves for automotive power network Automotive electronic equipment may encounter power transient interference during startup and operation. To ensure that the equipment can withstand the test, it is necessary to simulate harsh working conditions during testing. According to relevant industry standards, TBD-series can output various standard curves to achieve instantaneous voltage drop at car startup and various automotive electronic test pulses to test the performance of electronic equipment.
When high power output is required, power supplies of same specification can be connected in parallel to achieve capacity expansion. Parallel connection is simple, without complicated operation,
hardware synchronization, accurate and reliable.
Color touch screen combined with physical buttons, flexible operation and comfortable use.
It has a graphical upper computer operation interface, which can easily realize functions such as sequence test, photovoltaic simulation, battery simulation, battery charge and discharge test, etc.
