Clinton HF-15AC Digital High Frequency Sine Wave Spark TesterCondition:* Used, powers on, unable to fully test.* Sold as-is. As pictured. Additional Notes:* 3 kHz high frequency spark testing* Versatile control configurations & communication options* Test voltages 500v to 15KV rms* Digital voltage and fault count displays* Wide range of electrode styles* CE approved* The spark tester is an All-in-One conf iguration– display panel and spark tester– with an RS-485 serial interface that can receive and respond to digital commands. * Spark tester voltage can be set or verified, the fault count and interlock status can be monitored, and many other tasks can be performed by computer or PLC.* Voltage Test Range: approx. 500 volts to 15KV rms. (Min. test voltage varies on electrode design.)* Voltage Display: red 3-digit 14.2mm high LED display, accuracy 2% of reading.* Test Frequency: 1000 to 3500 Hz, depending on load capacitance.* Output Power: 4 ma. resistive, 40 ma. capacitive.* Fault Indication: red 3-digit 14.2mm high LED display; amber indicating light.* Fault Resolution: variable with electrode length to comply with UL fault resolution requirements, which specify detection of faults no farther than 24 inches apart at any wire line speed.* Detection Sensitivity: Mode 1 per British Standard BS EN 50356 Mode 2 per NEMA Standard WC 56* Operating Modes: Continuous HV/Remove Voltage on Fault, Momentary Process Control/Latch until Reset.* Process Control: Relay form C contacts rated 1 amp max @ 240VAC, 2 amps max @120VAC, for both NO and NC circuits. Front panel or external reset. In non-latch modes, closure time is adjustable in 10 millisecond increments from 50 milliseconds to 2-1/2 seconds. * Power Requirements: 100 or 120VAC, 2 amps, 200 or 240VAC 1 amp (selectable), 49-61 Hz.Clinton HF-15AC
