1: General Description

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.
