Guide
Redundancy, Selectivity & DC Converter Modules buying guide
What's in this range
- SITOP PSE200U and RED1200 redundancy modules for two parallel supplies.
- SITOP SEL1200 and SEL1400 selectivity modules that isolate a faulty branch.
- SITOP BUF8600 buffer modules and PSU3400 DC/DC converters.
- SINAMICS DCM 2-quadrant and 4-quadrant DC converters.
How to choose
- Redundancy module: match rated current to the supply and the total load.
- Selectivity module: pick the channel count and trip current per channel.
- DC converter: define armature voltage and current, and choose 2-quadrant or 4-quadrant.
FAQ
Redundancy, Selectivity & DC Converter Modules questions
Why use a redundancy module?
It keeps the load running if one supply fails and stops a faulty supply from pulling down the other.
What does a selectivity module do?
It switches off only the faulty 24 V DC branch. The others stay powered.
When is a 4-quadrant DC converter needed?
When the motor must brake or reverse under power control. Otherwise 2-quadrant is enough.
