SAELSeries of energy-feeding electronic loads

SAELSeries single-phase/three-phase energy-feeding programmable electronic load

SAEL series single-phase/three-phase modular energy feedback programmable electronic load is a new energy feedback electronic load device with high cost performance independently developed by Xinchi.

Various power products: such as regulated power supply, UPS, fire emergency power supply, DC power supply, charger, generator, etc., all need to carry out load aging and test before leaving the factory. The traditional method is to use resistance to discharge energy consumption. On the one hand, it will consume a lot of electric energy, on the other hand, it will greatly increase the capacity of power transmission and distribution equipment, and the heat released will increase the burden on the air conditioner.

SAEL series energy feedback electronic load uses power electronic conversion technology to recycle and regenerate the output energy of the power supply under test under the premise of completing the test power experiment. The AC power of the power supply under test is sent to the DC bus through the controllable rectifier. The grid inverter, which feeds the electric energy back to the power grid with high efficiency and no pollution, not only saves electric energy but also does not generate a lot of heat, avoids the problem of elevated ambient temperature in the test site, and can greatly improve the working environment.
