Applications

Heavy machinery assembly plants: Ensure the logic power supply of high-power drives does not reset due to voltage fluctuations when handling heavy-duty parts.

Precision die-casting plants: Stably filter power ripple in high-temperature and high-electromagnetic-interference environments, protecting sensitive control chips.

Semiconductor automation plants: Provide clean DC power distribution, avoiding micron-level trajectory deviations caused by power supply noise.

Automotive painting plants: Ensure communication and power synchronization during continuous painting operations, preventing paint defects caused by downtime.

Food processing plants: Support control cabinet operation in washing environments, providing overcurrent protection for power interfaces.

Competitive Advantage

Overvoltage, undervoltage, overload and short circuit protection

FAQ

Q: Is the DSQC604 3HAC12928-1 itself a switching power supply (UPS/SMPS)?
A: No. The DSQC604 3HAC12928-1 is a power distribution board. It receives 24V from an external high-power supply module, filters it, and distributes it to each drive axis.

Q: Why is the drive still not powered after replacing the DSQC604 3HAC12928-1?
A: Check the fuse or circuit breaker under the module. The DSQC604 3HAC12928-1 only handles low-voltage logic distribution; the 400V drive power is controlled by external contactors.

Q: What should I do if the DSQC604 3HAC12928-1 power connector is burnt?
A: This is usually caused by localized overheating due to loose wiring. Do not attempt cleaning—replace the board and matching connector cables to avoid fire risk.

Q: How does the DSQC604 3HAC12928-1 protect the driver from overvoltage damage?
A: The DSQC604 3HAC12928-1 includes onboard TVS (Transient Voltage Suppressor) and protection diodes to absorb small surge currents, but it cannot protect against lightning or severe high-voltage interference.

Q: How do I determine if the DSQC604 3HAC12928-1 power output is faulty?
A: Disconnect all loads and power only the DSQC604 3HAC12928-1, then measure the output terminals. If no voltage is present, the internal circuit is likely damaged.
