The power supply units can serve as a DC supply or external supply for the control electronics of frequency inverters and servo drives.
With the control electronics powered separately, parameter setting and diagnostics are possible without mains voltage, and communication over networks continues uninterrupted. This is particularly helpful during commissioning and when servicing the drive.
The range consists of 24 V DC models with 5 … 20 A output current and a 48 V DC model rated at 10 A. The IP20 units are mounted on the wall or base of the control cabinet, wired via screw terminals and operate between –10 °C and +55 °C.
Features
Control electronics supply
The units power the control electronics of inverters and servo drives externally.
Parameter setting without mains
Parameter setting and diagnostics can be carried out without connecting mains voltage.
Uninterrupted network communication
Fieldbus and network communication continue even while the power section is off.
24 V and 48 V options
24 V DC models deliver 5 … 20 A, while the 48 V DC model provides 10 A.
Applications
- Supplying servo drive control electronics
- External 24 V supply for frequency inverters
- Commissioning and parameter setting without mains power
- Maintenance and service work
