HT9460 and HT9464 Both are the U.S. HT-world company produced and authorized by the Shenzhen EUTTEST agent sales of high-voltage isolation voltage test system, our company provides two types of products offer and after-sales installation and training services.

The HT9460 and HT9464 are both designed for accurate and non-destructive production testing of digital isolator chips for AC isolation voltages and partial discharges. Complying with standards DIN VDE V 0884-11:2017, IEC 60747-5-5, UL1577, with more than 600 systems installed worldwide, the HT9460 and HT9464 series of test systems are the standard and preferred systems used by the majority of semiconductor manufacturers producing optical isolation devices. They provide a practical and automated solution for accurate production voltage isolation testing. The systems are specifically designed to test the input and output isolation of the following electronic components:

• Optocoupler, Optocoupler IC Digital Isolator
• Solid State Relay
• Pulse Transformer
• Optical Circuit Breaker
• isolation amplifier
• Conforms to standard DIN VDE V 0884-11:2017
• Conforms to standard IEC 60747-5-5
• Conforms to standard UL1577

Both the HT9460 and HT9464 systems ensure that the devices you produce will meet the stringent UL and VDE-0083 isolation test specifications as well as the VDE-0884 partial discharge specification.

HT9460 and HT9464 Manual Test Systems for Sample/Lab Testing

The HT9460 and HT9464 have the same test functions:

Isolation voltage and partial discharge testing

The HT 9460 and HT 9464 test systems detect resistive and capacitive leakage. the HT 9464 also measures partial discharges and meets UL and VDE 0883 specifications up to 7 KVA (9.99 kV peak). the HT 9464 also measures partial discharges and meets UL and VDE 0883 specifications up to 7 KVA (9.99 kV peak).

Partial Discharge Detection

Partial discharge activity indicates the presence of physical insulation defects that can lead to significant leakage and failures after the equipment has been placed in service.The HT 9464 is unique in its ability to detect partial discharges with a sensitivity of less than 5 picocoulombs (pC) as specified in the VDE-0884 specification. The optional calibrator PDC 710 can bePerform repeatable calibrations from 1 to 9 picocuries.

non-destructive testing

Isolated voltage testing often damages equipment due to the release of stored energy.The HT 9460 and HT 9464 produce negligible stored energy and feature a current-limiting design that prevents additional damage to faulty equipment. Voltage is applied to the DUT at the AC voltage crossing point. if a fault is detected, a solid-state switch removes the test voltage within 0.1 ms. the HT 9464 adds the unique benefit of non-destructive partial discharge testing.

Complete operator control

Provides front panel controls to set equipment leakage, high voltage/low limit thresholds and test limits for Part 9464 discharges. Digital panel meters display actual device voltage as peak or AC, supply voltage or leakage current. The front panel also displays a "pass/fail" message.

Manual Configuration

Both the HT9460 and HT9464 are available in manual and automatic processor models. The manual versions are ideal for inbound inspection, sampling and laboratory analysis of equipment or components where high throughput is not a priority.

Automated Handler Configuration

For production applications, the testers HT9460 and HT9464 can be fully integrated with most autoloaders. Handlers can be programmed to allow assignment of any exit slot to any sort class. An automatic retest indicator is also included. Typical throughput is 2,000 to 2,400 units per hour with a one-second assigned test time.

The basic configuration of the HT9464 automated test system includes:High voltage test head, controller and line filter. The controller front panel is reversible to allow horizontal or vertical mounting.

Options for HT9460 or HT9464

The figure above shows the options available for the HT9460 or HT9464 autoprocessor configurations:

1. PDC 710V Partial Discharge Calibrator (PDC Calibrator required by CDE standards);

2. Optically isolated processor or robot interface;

3. Verification Table. The Verification Bench is used in conjunction with the High Voltage Test Head to calibrate/setup the system offline in a simulated environment with no operator connected. Optoisolators are only required for processors that do not have their own opto-isolated bus. the PDC 710V injects a selected known charge (1 to 9 pC) into the device under test (DUT) contacts. This calibration technique simulates the partial discharge of an actual device so that all stray capacitances can be calibrated.

Safe and easy to operate

The HT9460 or HT9464 is designed for simple test operations.Safety lock prevents operator access to high voltages. 3-1/2 digit display of actual voltage helps set desired test voltage. Clear hinged lidPrevents inadvertent operation of the adjustment knob.

Difference between HT9460 and HT9464

From the above content can be seen, HT9464 and HT9460 two kinds of isolation voltage tester can complete the isolation voltage test and partial discharge test of the digital isolator, but the two models of the tester is still different, as can be seen from the following table, their measurable voltage is different, and the measured leakage current coulomb number is also different.

Above are the differences and similarities of HT9460 or HT9464, in general, except for the difference in output voltage and other parameters, the two devices are exactly the same in other aspects of the function, so you only need to choose to buy HT9460 or HT9464 from us according to the test standards and output voltage requirements.
