1.5 Technical Information
1Input voltage 110 V ac ± 10% or 230 V ac ± 10% - 50/60 Hz
2Output voltage 12 V dc
Output current 750 mA
Output ripple/noise 150 mV max
Line regulation <5% over the input voltage range
Load regulation <5% over 0 to 90% of load current
<10% between 90% and 100% of load current
Voltage limiting Over voltage detection with crowbar protection and
short circuit protection
Current limiting Automatic current limiting of the intrinsically safe
output also limits the current to less than the
rupturing capacity of the output protection fuse.
