Frequently Asked Questions
Can I set different current limits for each channel?
Yes, each branch can be individually adjusted to match specific load requirements.
What happens if one channel shorts out?
Only the affected channel will trip. The rest of the system remains powered and operational.
Is it easy to install?
It supports standard 35mm DIN-rail mounting with high-quality screw terminals for secure wiring.
Does the S8AS support abnormal voltage detection and recording?
Yes. The S8AS series can detect and display input voltage fluctuations. It also features a "peak current holding" function, which records the maximum current drawn by each channel. This is extremely helpful for diagnosing intermittent faults that are otherwise difficult to capture.
What is the "Maintenance Forecast" based on, and how accurate is it?
The forecast is based on the health of the internal electrolytic capacitors, which are the most life-limited components in any power supply. The S8AS calculates the remaining service life based on internal operating temperatures and load history, providing a reliable multi-year countdown to help you plan preventative replacements.
Can I manually trip or reset a channel without using the front buttons?
Yes, on models with RS-485 communication (R-suffix), you can remotely reset or trip individual channels through your PLC or PC. Additionally, there is a dedicated external input terminal for emergency remote shutdown, allowing for quick system-level isolation when needed.
