FAQ

Q: Can this module handle high inrush currents from motors or solenoids?
A: Yes, the DSPP4LT supports short-term peak currents of up to 50 A to accommodate startup surges.

Q: Is active cooling required for continuous operation at full load?
A: No, the module’s high efficiency reduces heat, but adequate ventilation is recommended to ensure thermal protection does not trigger.

Q: How do I protect connected devices from voltage fluctuations?
A: The DSPP4LT maintains a stable 24 V DC output despite variations in input voltage (100–240 V AC), protecting sensitive electronics from brownouts.
