Difference between HT9464 and HT9464M

Introduction:

When EUTTEST promotes isolation voltage and partial discharge testers to its customers, it will often recommend the HT9464 and HT9464M to its customers, and every customer will ask for the first time what is the difference between the two devices? First of all, it should be clarified that EUTTEST is selling two devices at the same time, there is no substitution between them, we will recommend the most suitable device to our customers, of course, you can also refer to learn the following we organize the similarities and differences between the HT9464 and the HT9464M to make a choice, if you still have questions after reading this, you are welcome to contact EUTTEST for help.

The HT9464 and HT9464M devices are identical:

The test criteria are the same:

Both devices can be used for magnetic and capacitive couplers and digital isolators that need to meet the basic or enhanced isolation certification testing, such as IEC 60747-5-1, DIN EN 60747-5-5, VDE 0884-10, VDE V 0884-11, UL 1577 and other optocoupler safety certification standards requirements, more information on the test standards can be referred to:What standards need to be looked at for optocouplers or digital isolators for safe electrical isolation?

The test function is the same:

Both devices support isolated withstand voltage and partial discharge testing, such as specified in the standards mentioned aboveViso Withstand Isolation Voltage and Viotm Maximum Transient Isolation Voltage,Qpd partial discharge testThe

From the above two similarities, we can see that the basic functions of the two devices are the same, so they do not have a substitution relationship, the following focus on understanding what is the difference between the two devices.

Difference between HT9464 and HT9464M:

Operational differences:

Let's start with the most obvious comparison of the device's appearance.

HT9464: Basic Low Voltage Isolation Voltage and Partial Discharge Tester, with knob + key control, suitable for manual operation and small batch testing, can also support the addition of sorting machine automation testing.

HT9464M: High Voltage Isolation and Partial Discharge Tester with display, equipped with a color touch screen to support more advanced features and automation integration.

Specification parameter differences:

Note: Although the HT 9464 output voltage is relatively low, it is sufficient for most optocoupler or digital isolator chip tests. So it should be considered in a limited way with your own needs.

Key point: Peak voltage = RMS × √2. For example, 10kV RMS corresponds to ±14.1kV peak, which is the actual instantaneous electric field strength to which the insulation is subjected.

Summary:

We have compiled the following table shows the demand scenarios and recommended models of the corresponding table, both devices can complete the insulation withstand voltage and partial discharge test, but focus on whether the test voltage to meet their testing needs, in addition to reference to whether you want to realize the far-field control to select the type.

These are the differences and similarities between the HT9464 and HT9464M devices. If you still have questions, please contact EUTTEST sales for more information.
