Mechanical relays have much smaller
output voltage drops (approaching zero), so unless there is a compelling reason to use a SSR, I'd be inclined to go with a mechanical relay.
Not exact matches
Some indicators compensate for
voltage drops occurring between the indicator and load cells by increasing the indicator excitation
output voltage; other indicators compensate for this
voltage drop by amplifying the load cell return signal.
To test the maximum current
output, we slowly turned up the load of our simulated device and recorded the
output when either the battery shut down or the
voltage dropped below the acceptable level.
