Appendix
| EMEX Power detailed specification
2.0 Central inverter system
The system should offer the following standard
features as summarised below and further detailed in
sections 3.0, 4.0, 5.0, 6.0 & 7.0:
1. True AC/AC 50/60Hz output
2. Ability to use standard proprietary AC distribution
and protection devices on outgoing circuits
3. Rated for any load power factor, zero to unity, at
any output power up to the maximum rated KVA
4. Compatibility with addressable test package using
EMEX technology
5. Excellent overload capability in full emergency
mode: 200% for 10 seconds without reduction in
output voltage
6. Excellent recharge capability – 80% after
12 hours following rated discharge
7. MCB protection throughout – no fuses
8. EMEX Power true modular construction with
common spares (inverter, charger, control PCB,
and system interface common across the full
system range)
9. Individual MCB protection for each module
– AC and DC circuits
10. Individual cooling fans for all modules with
on-demand operation (not continuously running)
11. Split parallel charger above 10 amps – enhanced
integrity with the ability to operate with one
or more charger modules isolated (subject to
increased recharge time)
12. Integral maintenance bypass facility (ability
to support output load in bypass mode whilst
maintenance is performed)
13. Temperature compensated charger
14. Comprehensive display
15. Charger and inverter alarm pack
16. Momentary “push to test” button
17. Fire alarm interface
18. Final exit interlock
19. Internal and external MCB monitoring
20. Local/remote maintained circuit control
21. Sub-circuit monitor connection
22. Two sets of volt–free alarm relay contacts
23. Inverter-inhibit engineers’ switch
24. Remote Alarm Unit option
25. Easy front panel access
26. Inter-cabinet trunking for battery cables
27. Fork-lift plinth
28. Lifting eyes for crane lift as standard
29. Cabinet levelling feet available
30. Installation pack with tools included
31. Detailed instruction manual
32. Transfer time both directions max. 0.5 seconds
