Leadshine SPS407-L is a unregulated switching power supply specially designed for powering stepper & servo drives in motion control applications, which have limited installation space and require light weight. At ultra compact size, it can take 180-250 VAC input and output 200W continuous power. At 120 VAC input, its output voltage is 42 VDC and can supply 4.7A continuous current. It can response very quick to the current change requirements.
SPS407-L is capable of taking back EMF from stepper & servo motors. When adopted in your stepper/servo systems, SPS407-L can provide the power you need and ensure that you won't get your stepper/servo drive damaged because of high back EMF charged back during movement de-acceleration.
