DURADRIVE Drive Controllers DC24V NTM power supplies 5-1
DOK-DURADR-HDC01.1****-PR02-EN-P
5 DC24V NTM power supplies
5.1 Application recommendations
If there is no external DC24V control voltage available, then Rexroth
Indramat recommends the use of NTM power supply units.
• The power supplies contain an overvoltage safety switch with
automatic shutdown. After the automatic shutdown device has
responded, operation can be resumed by switching the power supply
off, briefly, and on again.
• The power supplies always function with a starting current limiter.
However, if you switch off and on again within a period of 10 s, the
starting current limit do not work!
• The NTM01.1-024-004 and NTM01.1-024-006 power supplies make it
possible to measure the voltage applied to the load via cable sensor.
If there is a voltage drop, the power supply will increase the output
voltage accordingly.
• Installation in enclosed control cabinet required.
Rexroth Indramat recommends a 10A automatic circuit breaker with
tripping characteristics C for DC24V NTM power supplies.
Note: Mains filters are available to comply with EMC-limits. For a
selection of information see project planning manual
"Electromagnetic Compatibility (EMC) in Drive and Control
Systems", doc.-type DOK-GENERL-EMV********-PRxx.
