2 Technical Data
Power supply 115 / 230 V AC +/- 15 %;
50 / 60 Hz
24 V DC -25 % / +33 %
Load AC: P
max
: 12 VA
DC: P
max
: 7 W
Standard delivery 230 V AC
Fuses 24 V DC: fine-wire fuse 500 mA/tr
115 / 230 V AC: temperature fuse in the
transformer
The power supply must only be made via separator (switch or circuit breaker)! The switched
used as a separator must meet the requirements according to IEC 60947-1 und IEC 60947-3
and be suitable for application
Caution
Only one type of power may be connected at one time.
