The purpose of this section is to make clear the generator controller specifications meaning

Supply voltage: the voltage range of the battery to guarantee a good performance of the controller.

Beyond the specified limits the controller may not work or could suffer severe damage.

Supply over voltage: the maximum non-repetitive voltage on the supply terminal (0,1/1 sec)

Operating temperature range: /Humidity range. Climatic limits in which the controller can work normally.

Static outputs characteristics: the maxim voltage and current provided by a single output

Logic: positive (PNP output) or negative (NPN)

Generator Nominal Voltage Input: the voltage operational limits of the generator controller.

Damage may be expected applying voltage beyond the specified limits, for uncontrolled period of time.

Measurement precision: the maximum error of a measurement

Current transformer input size: the minimum and maximum size of a current transformer (5Amp secondary current)

Digital inputs voltage: the maximum measured voltage when the input is 'open'

Digital inputs current: the maximum measured current when the input is 'closed'

Trigger level: the level of voltage that switches the logic condition H>L or L>H

Definition of 'Resolution': smallest discernible change of measurement result due to a minimum change in the input.

Definition of 'Accuracy': deviation from the actual value as fixed by universally accepted standards of frequency and time.
