Frequently Asked Questions
Can I use the MDD01M-09 in a 12V nominal automation system that needs ±9V rails?
Yes, this model accepts a 10-13VAC input and delivers a ±9V constant-voltage output. With a 1W rating and 0.06A output current, it is suited to low-power automation electronics that specifically require ±9V.
Is the MDD01M-09 appropriate for embedded sensor or measurement circuits that run on ±9V?
It can be used in embedded measurement or sensor-support circuits where the required rail is ±9V and the load fits within 1W and 0.06A. The small 19.5 × 12.5 × 9.8 mm form factor is also useful on compact boards.
Can this converter fit low-power industrial interface modules with a 10-13VAC source?
This part is intended for 10-13VAC input conditions and provides a stable ±9V output in constant-voltage mode. That makes it a practical fit for low-power industrial interface or conditioning stages that need ±9V rather than 5V, 12V, or 15V.
Is the MDD01M-09 suitable for wide-temperature indoor equipment?
The stated operating temperature range is -40°C to +85°C, so it can be used across a wide temperature span inside equipment. Since no IP rating is listed, it is better suited to indoor enclosures or protected housings than direct outdoor exposure.
What are the other output choices in the MDD01M family besides the MDD01M-09?
The sibling models listed in the 1W MDD01M range are 5V at 100A for MDD01M-05, 5V at 16A for MDD01M-05N, 12V at 0.04A for MDD01M-12, 12V at 18A for MDD01M-12N, 15V at 0.03A for MDD01M-15, and 15V at 18A for MDD01M-15N. The MDD01M-09 provides ±9V at 0.06A.
