The Yaskawa CPS-420F is a control power supply unit specifically designed for MOTOMAN NX100 robot controllers. Here's a refined summary of its key features:

1. Purpose: Delivers stable DC power (typically 5V and 24V) to the CPU and internal control circuits of NX100 systems.
2. Input Specs: Accepts 200–240V AC, 50/60 Hz, with a current draw of 3 A.
3. Form Factor: Rack-mountable unit with dimensions around 31 cm × 20 cm × 7.8 cm, weighing approximately 3.9 kg.
4. Compatibility: Works with NX100-based robots like EPX2800, EPX1250, and EPX2050.
5. Cooling System: Includes an internal fan—failure can trigger a system alarm (e.g., FAN ERROR 4119), requiring inspection or replacement.
6. Reliability: Known for robust performance in industrial environments; available in new, refurbished, or exchange options with warranties from 6 to 24 months.
