HT-9464M High Voltage Isolation Voltage Tester and Partial Discharge Tester (Old Model HT9464M)

Product Description:

The HT-9464M is a high-voltage isolation voltage tester and partial discharge tester from TORQUIL, and is designed to be used in conjunction with theHT9464Likewise, the 9464M provides the AC voltages needed to perform leakage and partial discharge tests for equipment insulation boundaries where dielectric strength is critical (e.g., optocouplers, digital isolators, optical triacs, capacitive couplers, inductive couplers, Hall effect current sensors, solid state relays, pulse transformers, conventional relays, short coaxial cables, (circuit board interlayer dielectric materials, etc.). The tester is equipped with safety interlocks to enable operators to use the equipment safely within the maximum output voltage range. This product has been authorized by EUTTEST Shenzhen for worldwide sales and quotation service.

This equipment ensures that the product under test complies with the requirements of insulation voltage test standards such as IEC 60747-5-5, VDE 0884-10 / VDE 0884-11 and UL1577.What do these insulation test standards require of digital isolators?？

This device is CE certified and complies with the following standards:

Product Features:

• Supports dual- or four- or even eight-station testing with a sorter to easily meet the testing volume requirements of large OEM factories.
• Retrofitting and retrofitting of sorters for automated placement and pickup of chips for testing.
• Detects UL and VDE regulated resistive and capacitive leakage up to 7.5kVrms with options up to 10.00 kVac-RMS and 13.00 kVac-RMS.
• Installed by most of the world's major high-volume manufacturers of optical semiconductor devices.
• Touch screen operation of keys and command inputs and outputs
• Fully computerized operation to meet the challenges of Industry 4.0
• Customize password-protected operator and engineer modes
• Client host has access to all setup and test result data
• Zero tester/processor footprint. Maximum throughput per square meter
• Optimized reliability metrics MTTR and MTBF are achieved with 3 board sets covering the system electronics of the 95%.

In addition, HT-9464M adopts the mode of separate design of high voltage module and analysis module, the terminals in the high voltage package will be connected to the adapter customized by EUTTEST for your product for testing (manual version), which can greatly reduce the influence of electromagnetic interference EMC on the test results.
