Input voltage 110 V ac ± 10% or 230 V ac ± 10%-50/60 Hz
Output 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.

1. Make sure that all covers on Ex e housings and their fixing devices are properly
secured in compliance with statutory regulations before switching on the input
supply.
2. Never remove the cover of an Ex e housing whilst the input supply is
connected. Isolate elsewhere before removing the cover in accordance with
statutory regulations.
3. The housing of all power supplies must be securely earthed in compliance with
statutory regulations.
4. Carry out a current consumption audit to ensure that the maximum current
loading of the power supply is not exceeded.
5. Ensure that the installation of the power supply, particularly with regard to the
connecting cables, complies with the certification parameters (section 2.1).
6. The Ex e housing must be inspected and maintained regularly in accordance
with statutory regulations.
7. All cables entering the mains input terminal chamber must be terminated with
suitable, certified cable entry devices.
8. Do not drill holes in the Ex e housing or modify it in any way.
9. The battery contains corrosive substances and must be disposed of in the
correct way.
10. Please return the complete unit to Trolex or an approved distributor for servicing
and replacement.
