Frequently Asked Questions

What input voltages does the SD833 support?

The SD833 automatically selects between 100-120V AC and 200-240V AC inputs. This makes it suitable for global use without manual configuration.

Can I use this power supply in redundant systems?

Yes, you can create redundant power systems using SS823 or SS832 diode voting units. This ensures continuous operation if one power supply fails.

What is the efficiency rating of this unit?

The power supply achieves 91-91.6% efficiency. This reduces heat generation and energy costs in continuous operation applications.

How does the soft start feature work?

The soft start gradually increases power during startup. This prevents tripping fuses or earth-fault circuit breakers in your electrical system.

What environmental conditions can it handle?

The SD833 operates in temperatures up to 55°C and handles ISA G2 corrosive atmospheres. It meets industrial pollution degree 2 requirements.
