SCI 446 – AC/DC Hipot (5kV/6kV) with Insulation Resistance and Ground Bond Testing

SCI (Slaughter) 446 – AC/DC Hipot (5kV/6kV) with Insulation Resistance and Ground Bond Testing

The SCI 446 is a 4-in-1 tester with AC Hipot, DC Hipot, Insulation Resistance, and Ground Bond capabilities. This tester features a simple design and easy-to-use interface, reducing setup time and increasing production-line throughput for your application. The 446 is equipped with multiple memories and an optional USB port for remote BUS communication so you can quickly perform tests on a variety of DUTs from the front panel or with a PC. Add to user safety by equipping your tester with Personal Protective Equipment (PPE) via the built-in safety interlock.

Two models available

There are two models in the SCI 440 series. The main features of each can be viewed in the chart below.

Front panel controls

1. Reset button – momentary contact switch used to reset the tester
2. Test button – momentary contact switch used to start a test
3. LCD display – main readout for the operator and programmer of the test settings and test results
4. High voltage output jack – for connection of the detachable HV test lead or the adapter box HV connector
5. Power switch
6. Rotary knob – used to advance forward/backward through the setup menus and to setup system and test parameters
7. High voltage arrow (LED indicator) – flashes to warn high voltage is present
8. Current output terminal – used to attach the high current output lead, adapter box high current lead or test fixture high current lead to the instrument. This connection provides the output current for the ground bond
9. Return terminal – used to attach the return test lead, adapter box return lead or test fixture return lead to the instrument. This connection provides the return current path

Rear panel controls

1. High voltage output jack – Use this jack for the connection of the detachable HV test lead or the HV adapter box
2. Return terminal – Used to attach the return test lead, adapter box return lead or test fixture return lead to the instrument. This connection provides the return current path
3. Current output terminal – Used to attach the high current output lead, adapter box high current lead, or test fixture high current lead to the instrument. This connection provides the output current for the ground bond
4. High voltage arrow (LED indicator) – Flashes to warn the operator that high voltage is present at the high voltage output terminal
5. Calibration enable key – To enter the calibration mode press this key while the tester is being powered on
6. USB connector – USB port for serial communication. Refer to Remote Bus Interface section page 50 in user manual
7. Remote output – 9 pin D subminiature female connector for monitoring PASS, FAIL, and PROCESSING output relay signals
8. Remote input – 9 pin D subminiature male connector for remote control of test, reset, and interlock functions as well as remote memory tests selection
9. Chassis ground earth terminal – This safety ground terminal should be connected to a good earth ground before operation
10. Fuse receptacle
11. Input power receptacle – Standard IEC 320 connector for connection to a standard NEMA style line power mains cord
