Frequently asked questions
1. Does RD-125A provide two outputs?
Yes. CH1 is 5V and CH2 is 12V. Check the terminal diagram before connecting either load.
2. Can both channels use their maximum current-range values at once?
Do not assume so. The combined load must satisfy the total power rating and the channel-loading conditions in the manufacturer specification.
3. Is the AC input range automatic?
No. The specification lists 88–132VAC and 176–264VAC ranges selected by a switch. Match the selector to the supply before energizing.
4. Is RD-125A the same as RD-125B?
No. RD-125A provides 5V and 12V; RD-125B has a different output combination. Confirm the exact model when replacing a unit.
