Frequently Asked Questions
Can I use the ERDN20-48 for a 48V redundant telecom or industrial DC bus?
Yes, it is a 48V constant voltage redundancy module rated for 20A and 960W. The support for 1+1 and 1+N redundancy makes it relevant for systems that need redundant 48V bus continuity.
Is the ERDN20-48 a fit for 48V automation systems with high current demand?
It is designed for 48V loads up to 20A, with a total power rating of 960W. That capacity suits higher-power 48V control and industrial DC systems that require redundancy rather than a single-source design.
Can the ERDN20-48 be used where power-loss monitoring is required on a 48V rail?
Yes, the listed features include relay contacts for monitoring power status. Combined with its 48V, 20A rating, that makes it applicable where redundant 48V power status needs to be supervised.
What is the difference between ERDN20-48 and the other ERDN20 voltage versions?
The ERDN20 siblings listed are ERDN20-5 at 100W and 5V, ERDN20-12 at 240W and 12V, ERDN20-24 at 480W and 24V, and ERDN20-48 at 960W and 48V, with all models rated at 20A. ERDN20-48 is the highest-voltage and highest-power version in that sibling group.
Can the ERDN20-48 handle low-temperature or high-temperature industrial environments?
The specified operating range is -40°C to +80°C, so the temperature rating is broad for industrial use. No IP rating is provided, so the published specs do not establish outdoor exposure protection.
