5. Variac and Auto volt
switcher
Variac –
We are using two variacs for
170V and 250V.
Auto Volt Switcher-
It is a programmable switching
device. Four Buttons enable
output in any one of 4 modes:
1. Relay1-170 volt
2. Relay2-250 volt
3. Zero output
4. Auto mode- in this mode it
provides zero volt, 170V and
250V for 5 sec each.
The objective here is to check
and store all readings at two
different voltage inputs.

6. Software
Software-
-It is easy to configure limits.
-It automatically detects the
test mode from Volt-switcher.
- You can save in csv data on
two/three different voltage
levels on a single button.
