The SDB series is a bidirectional programmable DC power supply that integrates DC power supply and feedback load. It can achieve the function of SOURCE to provide energy to the load, as well as the function of SINK to absorb load energy and feedback it to the grid, achieving dual quadrant operation.
The SDB series can reach a maximum voltage of 2250V, support multiple parallel machines, achieve power expansion, and is widely used in fields such as automotive electronics, power batteries, photovoltaics, energy storage testing, etc.
(11) Support multiple remote controls, standard RS232, optional RS485, CAN, LAN, etc
Typical recommendation
Dual directional flow of energy, fast switching
The SDB series integrates source and load design to achieve high-speed source load current mode conversion, allowing for quick switching between output current and absorption current, effectively avoiding voltage or current overshoot.
Oscilloscope mode displays real-time simulated curves of solar cell arrays
The SDB series power supply is equipped with standard SAS models such as EN50530 and Sandia, which can simulate the IV/PV curve of solar cell arrays. After the user sets the parameters, the curve can be generated internally and output for testing the static and dynamic maximum power tracking performance of the inverter. At the same time, this mode has oscilloscope function, which can display IV/PV curves on the interface and real-time display the current working coordinate point, simple and intuitive.
Implement multiple standard automotive power grid curves
Automotive electronic devices may encounter power transient interference during start-up and operation. To ensure that the equipment can withstand testing, it is necessary to simulate harsh working conditions during testing. According to industry standards, the SDB series can output various standard curves to achieve instantaneous voltage drops during vehicle start-up and various automotive electronic testing pulses for performance testing of electronic devices.
