Standard features, options and batteries | EMEX Power
Performance
l True AC/AC 50/60Hz output
l Ability to use remote standard proprietary AC
distribution and protection devices on outgoing
circuits
l Rated for any load power factor, zero to unity, at
any output power up to the maximum rated KVA
l Compatibility with addressable test package
using EMEX technology
l Excellent Overload Capability in full emergency
mode: 200% for 10 seconds without reduction
in output voltage
l Excellent recharge capability: 80% after
12 hours following rated discharge
l MCB protection throughout – no fuses

Standard features: EMEX Power system overview
EMEX Power offers a host of standard features and benefits, as listed below. Note that some items will be optional,
extra cost items on other systems, or may not be available at all if the system is not designed specifically and solely
for emergency lighting use.
For further detail, please refer to the ‘EMEX Power detailed specification’ on page 84.
Batteries
Standard systems are supplied with Valve Regulated
Lead Acid (VRLA) batteries, also known as ‘Sealed Lead
Acid’. These batteries are sealed for their design life of
10 years.
Lead Acid Planté and Nickel Cadmium batteries are
available upon request, however, these batteries
require a much larger physical area, and emit
potentially explosive gases, meaning the battery room
must be adequately ventilated.
These reasons, along with the additional capital cost,
generally outweigh the additional life obtained, as
demonstrated below.
