Why Choose ePower Power Supply?
1.Traditional switching power supplies may generate overvoltage when motors operate in regenerative braking mode, triggering overvoltage protection and shutting down
2.They may also trigger overcurrent protection and shut down due to excessive current caused by sudden high loads.
3.The ePower power supply features dedicated circuitry that prevents overvoltage shutdown from regenerative braking and avoids overcurrent shutdown caused by transient high loads.
ePower Power Supply Series
The ePower series is a chassis-mounted power solution purpose-built for ZeroErr robotic joint modules. It converts AC input into stable DC output optimized for joint operations, and is available in 400W, 800W, and 1500W models.Designed for scenarios involving regenerative braking and frequent current fluctuations, ePower delivers reliable and consistent performance for robotic joints and modular systems.
Power
Our power supply units incorporate internal switching components that are certified to meet European Union CE certification.
