FAQ

Q: What safety standards does this power supply comply with?

A: It is designed to meet EN 50178, EN 61131-2, and UL 508 standards for electrical safety and function.

Q: Is it safe for low-voltage control circuits?

A: Yes, its secondary output is approved for SELV (Safety Extra-Low Voltage) or PELV applications.

Q: Can it be used in redundant power systems?

A: Yes, but for redundancy, it requires connection to a diode voting unit such as SS823 or SS832.

Q: Does it need an external mains filter?

A: No, the SD83x series does not require the installation of a separate mains filter.

Q: How does it handle startup current?

A: It features a soft start, which prevents tripping fuses or earth-fault circuit breakers during power-on.
