Application Scenarios: Thermal power plants, gas-steam combined cycle, nuclear power plants, large petrochemical DCS, metallurgical process control.
Installation Requirements:
- Install in Mark VIe rack dedicated power slot
- Dual-module redundant configuration must use Current Sharing Cable
- AC input must connect to UPS uninterruptible power supply
- Ground resistance ≤ 4 Ω
Usage Notes:
- Confirm input voltage matches module setting before power-on
- Never exceed rated current output, otherwise overcurrent protection triggers
- During module failure, redundant module automatically takes over with no system interruption
- Regularly clean cooling vents to ensure good ventilation
