Frequently Asked Questions
Can I use the MDR-20-12 for a small 12V PLC or control panel circuit?
Yes, it is suitable for small PLC or control panel loads that require 12V DC up to 1.67A. The 20W output is aimed at lighter-duty industrial control applications rather than high-current 12V loads.
Is the MDR-20-12 a good fit for industrial automation components that need 12V DC?
It can be used for industrial automation components inside a cabinet when the total 12V load stays within 1.67A. Its ultra slim 22.5 mm width helps in narrow DIN rail layouts where panel space is limited.
Can this power supply be used in building management control enclosures with 12V devices?
Yes, it is appropriate for building management enclosures that use 12V DC controllers, relays, or interface devices within a 20W power budget. The 85-264VAC input also supports a broad AC input range for building panels.
What is the difference between the MDR-20-12 and other 12V MDR models?
For 12V outputs in this series, the MDR-10-12 is 10W and 0.84A, the MDR-20-12 is 20W and 1.67A, the MDR-40-12 is 40W and 3.33A, the MDR-60-12 is 60W and 5A, and the MDR-100-12 is 90W and 7.5A. The main differences are output capacity and physical size within the same DIN rail family.
Is the MDR-20-12 suitable for control cabinet and enclosure use?
Yes, it is intended for protected control cabinets and enclosures rather than exposed environments. Its operating temperature range is -20°C to +70°C, which supports use in a wide range of indoor industrial panel conditions.
