ZeroErr ePower 48V Power Supply for Robot Joints, 400W/800W/1500W Options

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.
