Description
Hioki 3153 HiTESTER for Automatic Insulation and Withstand Testing
The Hioki 3153 Automatic Insulation/Withstanding HiTESTER is designed to meet the growing demand for efficient, reliable, and safe electrical testing. Combining both insulation resistance and AC/DC voltage withstand testing in one device, it streamlines the verification of electrical devices and components according to international safety standards.
Programmable Multi-Point Testing
Users can program up to 32 files with 50 test steps per file, covering multiple test points, voltages, and measurement settings. This flexibility ensures that complex testing procedures are automated, reducing human error and increasing production efficiency. The optional high-voltage scanner allows fully automatic multi-point testing, making the 3153 ideal for high-volume manufacturing and laboratory use.
Accurate and Stable Voltage Testing
The Hioki 3153 uses PWM technology to generate precise test voltages independent of fluctuations in the power supply. AC and DC voltage withstand tests can be performed up to 5 kV, with accurate current measurement from 0.01 mA to 100 mA. A ramp timer function allows controlled voltage rise and fall during dielectric strength tests, preventing stress on sensitive components.
User-Friendly Monitoring and Safety
The 3153 provides continuous digital monitoring of output voltage, detected current, and measured insulation resistance, with refresh rates of 2 times per second. Its compact design (320 × 155 × 480 mm) and lightweight construction (18 kg) make it easy to integrate into existing test setups. With included high-voltage test leads, power cord, instruction manual, and spare fuse, the device is ready for immediate use.
Applications
Ideal for testing electrical equipment, insulation components, and industrial devices in production lines or laboratories, the 3153 ensures consistent, reliable, and reproducible test results. Its automation capability enhances productivity while maintaining compliance with safety standards.
