ECU Energy Control Unit
1 Product Overview
The ECU observes alarm signals from the power and climate system and
protects the equipment within the RBS from conditions that could reduce
lifetime and reliability. The ECU protects the equipment during power failure
conditions and cold start-up.
1.1 Main Functions
The ECU has the following main functions:
• Controls power equipment (PSU, BFU, Battery and AC connection unit)
and climate equipment (fans, heater, cooler, and heat exchanger).
• Ensures that the climate is within the specified range for RBS start-up.
• Handles analogue sensor signals.
• Handles communication with the DXU via the local bus.
• Handles load sharing of PSUs (PSU 230 only).
• Regulates system voltage to the optimal system voltage for the battery
temperature (PSU 230 only).
