UPS systems Flashcards
Name 3 considerations when installing a rotary ups system
Fuel storage
Noise level
Exhaust fumes
Name 3 conditions when selecting a ups system
Size of the load being supplied
Standby duration
Do you want one large ups or multiple small ups
Describe what’s happens in an online ups system
The incoming Ac voltage is always monitored For transient voltages and only clean power reaches the sensitive equipment
Size of the battery is decided at the design stage to suit the load and standby time
The bypass switch is used in the event of an inverter failure
Describe the standby/offline ups
This type of system is used for non critical loads
The Incoming AC supply creates a magnet field in a coil closing the contact bypassing the ups when the ESB mains is healthy
When the ESB drops the relay coil de energises opening the relay witch then allows the ups to take over and power the load
