Kikusui AC/DC Hipot Tester TOS5301

The Kikusui TOS5301 is a high-performance AC/DC withstand voltage (Hipot) tester designed for insulation safety testing of electrical and electronic equipment. Featuring a PWM amplifier for ultra-stable output, high-accuracy measurement, and enhanced operator safety, it ensures reliable testing even in regions with fluctuating power supply.

Features:

  • Dual-mode testing: AC 5 kV / 100 mA & DC 6 kV / 50 mA (model dependent)
  • High output stability: PWM amplifier maintains constant voltage (±0.3 % variation)
  • High measurement accuracy: ±1.5 % of reading (≥ 500 V / ≥ 1 mA)
  • True RMS measurement with 1 V / 1 µA resolution
  • Fast testing: Minimum test time 0.1 s for high productivity
  • Rise/Fall time control for safe ramp-up and ramp-down
  • USB interface for data logging and automation
  • Key lock & actuator cover to prevent accidental operation
  • Worldwide input compatibility (100 – 240 V AC, 50/60 Hz)
  • New safety terminal design – color-coded, lockable, and strain-resistant

1. What is the Kikusui TOS5301 used for?

The TOS5301 is used to perform AC and DC withstand voltage (Hipot) tests to verify the insulation strength and electrical safety of products such as electronic devices, components, and power equipment.

2. What are the test voltage ranges of the TOS5301?

It offers a maximum output of 5 kV AC / 100 mA and 6 kV DC / 50 mA, with a total test capacity of 500 VA — suitable for a wide range of insulation and safety tests.

3. What makes the TOS5301 different from conventional Hipot testers?

The TOS5301 uses a PWM amplifier system that maintains a stable output (±0.3%) even when the input AC voltage fluctuates, ensuring consistent and accurate test results — unlike traditional slide-transformer designs.

4. How accurate is the measurement performance?

It provides high-precision True RMS measurement with ±1.5 % accuracy (≥ 500 V or ≥ 1 mA) and fine resolution of 1 V / 1 µA, allowing detection of poor connections or insulation defects quickly and reliably.

5. Does it include safety and usability features?

Yes. It includes a key lock, actuator cover, and a new output terminal design that prevents accidental operation, reduces cable stress, and ensures operator safety during high-voltage testing.

6. Can the TOS5301 be used globally?

Absolutely. It supports worldwide power input (100–240 V AC, 50/60 Hz) and is designed for consistent operation in any country, making it suitable for global production and QA environments.
