The SA100s Switchgear Analyser is an extremely light-weight & quick tool to check basic Circuit Breaker Timing and is an instrument intended for use in Power Station, Substation & industrial environments.
As the latest addition to our SA100 series, the s version is based on well established and proven technology used worldwide. Results are printed out and viewable on a built-in display, which also serves as a backup should printer paper not be immediately available.
INPUTS
Analogue: 1 x Independently controlled trip (open) and close coil current inputs.
Analogue Accuracy: <0.5% of fullscale.
Digital: 6 x Contact status inputs providing timing of up to 3 main contacts and 3 resistive contacts (‘dry’ contacts).
2 x User configurable input for ‘wet’ or ‘dry’ contact timing (24 - 250V DC or 0V DC).
Contact Threshold: 15 - 10,000 ohms.
