Comparison of Switching Power Supply and ePower.
1. Ordinary switching power supply will cause over-voltage due to kinetic energy recovery, triggering protection shutdown.
2. Ordinary switching power supply will cause over-current due to momentary large load, triggering protection shutdown.
3. ePower power supply has a dedicated processing circuit inside, which will not trigger over-voltage protection due to regenerative braking, and will not trigger over-current shutdown due to momentary excessive load.
About ePower
ePower is a chassis power supply designed and developed to help users use ZeroErr actuators. It can convert AC voltage into actuator usable DC output, and currently covers power of 400W, 800W, 1500W etc.. It is suitable for occasions such as rotary actuators and robots that generate regenerative braking and the working current changes frequently.
Feature
The internal switching power supply of our ePower applies MeanWell ERPF-400-48 and have obtained the CE certification.
