1.4.3 Power supply
Mains supply
As standard, the UFC instrument is designed to work with a mains supply of 86 to 236 Vac and 50/60 Hz. A mains
supply fuse is located adjacent to the mains power connection (see Figure 2.2).
24V Supply
An alternative 24 V (ac/dc) power supply module is available as a factory fitted option.
Power failure
The instrument will automatically power-up and become operational when the input power is applied. In the event
of a power failure, the instrument’s configuration parameters are stored in non-volatile memory which then allows
the instrument to return to normal operation immediately power is restored. A real time clock (RTC) records the
date and time of any power disruptions, and time-stamps any such occurrence in the output log. All data logging
ceases while power is unavailable.
