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.

Connecting cables must conform to the requirements of the appropriate
Approval and Certification standards for Mining applications. Trolex recommends
that they conform to BS5308.
rev A
Make periodic visual inspections to check for physical damage.
Check connections in both terminal chambers are secure.
Trolex recommends that the batteries are replaced every three years. This must be
carried out by a competent person. If the unit is returned to Trolex for this re-work,
a test of the internal safety integrity will also be carried out.
See Terms and Conditions for the Supply of Goods and/or Services at

rev A
Check the correct function of the mains-fail relay by connecting a suitable test
meter across the contacts.
A 12 V dc output should be available at the intrinsically safe output terminals with
mains power input present, or absent.
Also check that the analogue battery monitoring signal is available at the output
terminals.
If you need technical support to operate this product, or would like details of our
after sales technical support packages, contact .
The internal safety crowbars have activated due to an external
condition on the input voltage or output side, the crowbars will
attempt to automatically reset. If this does not happen remove main
power for about 2 minutes.
It is probable that the input fuses have ruptured which has resulted
in the batteries completely discharging. To check this, remove
main power momentarily. If the relay does not change state then
it confirms the unit is continuously operating on the battery supply
only.
