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.

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.
