Overview
ZeroErr ePower is a power supply for robot joints and robot rotary actuators. Selectable versions are ePower-400-48, ePower-800-48, and ePower-1500-48. All listed versions provide 48 V DC output and accept 100–240 V AC input.
Features
- Designed for robot joints and robot rotary actuators.
- Integrated top carry handle.
- Ventilation and rear-side power connections.
- Constant-current limiting for overload and short-circuit conditions, with automatic return to normal operation after the abnormal load condition is removed.
- Over-voltage protection turns off the output voltage, then restarts for recovery.
- Over-temperature protection turns off the output voltage and recovers automatically after the temperature drops.
