an external input during the motor is running |
|
|
Easy connecting via front side screw
terminals and spring terminals for all lines and signals |
|
|

|
| |
|
350 VA or 500 VA |
|
| |
|

|
| |
All power supplies include an additional
second 24VDC output voltage (max 2A) |
|
| |
For each plug port there is a seperate addtional
plug port for ventilator boards.
The ventilator boards can be ordered together with the rack or any time
later
and easily plugged into the ELK/ELR-rack.
(from aprox. 6A adjusted phase current a ventilation of the power amplifers
is necessary). |
|
| |
ELK-systems are also available for small
SE-units (SE 400.02.24 V31/V33 / SE P05.02.24 V2
or SE 400.01.85 V31/V33 / SE P05.01.85 V2).
The racks then are possible including power supply and max. 5 SE drives
or without power supply and max. 8 SE drives. |
