• Description


With its higher output voltage range, the popular S400 version 3 now fits perfectly with modern chargers that only achieve full charging power with a high input voltage. Despite its small dimensions, the small power supply has an output power of 400W with an input voltage of AC100V-240V. The high efficiency of the converter system of max. 92% ensures low losses and low heating. This powerful and programmable switching power supply has been specially designed for operation with RC high-performance chargers operating with up to 30V input voltage.
