- KIKUSUI TOS9300 series
The All-Rounder.Hipot,Insulation Resistance,Ground Bond,Leakage or Partial Dischage,this analyzer covers it all!
The TOS9300 series is a high performance electrical safety analyzer that complies to a wide range of universal standards.
A total of 6 models are available for standard compliance tests in a wide variety of applications including R&D,quality assurance manufacturing lines and laboratory tests.
5 Key Features
1． All-in-One Testing – TOS9303LC model covers AC/DC Hipot, IR, Ground Bond, and Leakage Current in one instrument.
2. High Capacity – AC 5 kV / 100 mA, DC 7.2 kV / 100 W output.
3. 40A AC/DC Ground Bond – New amplifier design supports high-current testing for automotive and EV systems.
4. Full Connectivity – LAN / USB / RS232C standard on all models.
5. User-Friendly Operation – 7-inch LCD with real-time measurement display and stored standard outlines.
Performance Highlights
・ Insulation Resistance: 0.001 MΩ to 100.0 GΩ
・ Ground Bond: 0.001 Ω to 0.600 Ω (3.0 A to 42.0 A)
・ Leakage Current: 1 μA to 100 mA (rms) – TOS9303LC
・ Partial Discharge Detection – TOS9301PD
・ Rise/Fall Time Control for reduced DUT stress
