off-grid automatic switching

FTDM series integrates off-grid and grid-connected switching circuit, which can realize the function of off-grid automatic switching.

Seamless switching between DC power supply and feedback load

Realizes the source and load current mode conversion, so that the output current and the absorbed current can be quickly and continuously switched seamlessly, effectively avoiding voltage or current overrush, and is widely used in battery, battery packaging, battery protection board and other energy storage equipment testing.

multi-machine parallel function

FTDM series adopts advanced control algorithm to realize multi-machine parallel, and the power level of parallel system can cover 1MW, which greatly expands the application output range of power supply. Parallel function in addition to the automatic load between the power supply, to maintain the output value is consistent, but also to ensure the output slope curve or waveform is consistent. In the parallel state of the host, the power supply screen displays the total voltage, current and power values. Each slave automatically equalizes current and sums automatically.
