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.

Digital Resolution: 100µSec.

Connectors: 4mm safety socket.

 

OUTPUTS

Coil Operation: Solid state outputs for trip (open) and close.

Coil Peak Current: 5A (accuracy 2.5mA) or 30A (accuracy 15mA) AC/DC measurement ranges selectable via input sockets.

Other measurement ranges possible via optional external shunt; for example 50A Peak (up to 75mS

duration) or 100A Peak (up to 50mS duration).

Coil Max. Voltage: 400V peak.

 

RECORDING

Resolution: 12 bit A/D (1:4096) and 10 kHz sampling rate.

Recording Time: Selectable up to 1 second.

Synchronisation: All inputs sampled simultaneously.

Start trigger: Coil current or selectable on any digital input.
