The InteliSENS® ST-AC series mains frequency spark testers from Proton Products comply with international standards stipulated for cable insulation testing: UL1581, UL2556, and EC62230. These AC mains frequency spark testers are designed for in-line cable testing to detect insulation faults such as pinholes and bare patches. They support cables up to 130 mm in diameter and provide a user-adjustable EHT test voltage up to 25 kV AC (rms). Typical applications include insulation testing of electrical and automotive cables. This unit offers a wide selection of integrated and optional industry-standard communication interfaces for connection to production controllers. The electronics of the InteliSENS® ST-AC series are housed in a robust IP54-sealed stainless steel enclosure, ensuring reliability and long service life.Maximum cable diameter: 130 mm300 mm long bead chain electrode25 kV maximum test voltageSeparately distinguishes and counts pinhole and bare patch defectsMains frequency testTesting compliant with UL1581, UL2556, and EN62230Ozone extraction portPerformance ST 2560ST 25100ST 25130Max. cable diameter60 mm100 mm130 mmElectrode length300 mm300 mm300 mmElectrode type5 mm bead chain5 mm bead chain5 mm bead chainEHT test output voltage25kV (rms)25kV (rms)25kV (rms)EHT test output voltage resolution0.1 kV (rms)0.1 kV (rms)0.1 kV (rms)EHT test output voltage accuracy2%2%2%EHT test capacitive output current (at 25 kV)9 mA (rms)9 mA (rms)9 mA (rms)EHT test resistive output current (at 25 kV)4 mA (RMS)4 mA (RMS)4 mA (RMS)EHT test output DC short-circuit current10 mA (rms)10 mA (rms)10 mA (rms)ConnectivitySafety interlock input to enable EHT test output voltageMaximum pulses: 50 V, maximum frequency: 250 kHz, user-scalableMaximum input voltage: 24VDC.
