FAQ

What is the difference between the TVD 1.2 and TVD 1.3 series?

The TVD 1.2 series, like this unit, is the earlier version within the DIAX02 family. The TVD 1.3 series introduced some internal hardware and firmware updates for improved performance and diagnostics, but they are generally not interchangeable without system adjustments. Always verify compatibility with your specific drive controllers.

What do the LED status indicators (H1-H4) on the front panel mean?

These LEDs provide basic diagnostics. H1 (Power OK) indicates the internal control voltages are present. H2 (Overcurrent) signals a short circuit or excessive current draw. H3 (Bleeder Overload) indicates the internal braking resistor is overloaded. H4 (Temp Fault) shows an over-temperature condition in the power supply or connected drives.

Does this power supply require an external braking resistor?

The TVD 1.2-08-03 has a built-in braking resistor (bleeder) to dissipate regenerative energy. For applications with high inertia or frequent, rapid decelerations, an external braking resistor (connected to RB1/RB2 terminals) may be necessary to handle the excess energy and prevent overvoltage faults.
