3.0 GENERAL REQUIREMENTS

3.1 Standards

CHLORIDE Power Protection is certified by the British Standard Institution (BSI) as a company with a total

quality control system in accordance with ISO9001.

POWER LAN series is designed and manufactured in accordance with the following international standards:

EN50091-1

EN50091-2 class B

IEC950

3.2 Components and materials

All materials and parts comprising the UPS shall be new and in current production, and to ensure maximum

reliability, they shall be used well within the parameters recommended by the supplier.

4.0 BATTERY MANAGEMENT

Using advanced battery care POWER LAN series shall increase the battery life by up to 30%. The main

battery care features shall include:

4.1 Ambient temperature compensated battery charger

To ensure optimum recharging of the battery, the floating voltage is automatically adjusted as a function of

ambient temperature (-0.1% per °C).

4.2 Autonomies

Autonomy is the length of time that the UPS can supply a load when a mains failure occurs, that is, when the

UPS takes energy from batteries.

POWER LAN has the possibility of activating an autonomy learning period through a dialog program. This

means POWER LAN supplies the load taking energy from the batteries until these are discharged and records

the time. This time will be stored internally as LEARNT AUTONOMY.

The learning training of autonomy must be completed with the batteries fully charged and with the user’s

typical load. In this way, the user will know which is his POWER LAN autonomy with his usual load.

In addition to LEARNT AUTONOMY, there are 3 further autonomy functions:

• POSSIBLE AUTONOMY.

During the discharge of batteries it is the value of the LEARNT AUTONOMY minus the already elapsed

autonomy minutes.

Example: if the LEARNT AUTONOMY is 15 minutes, there is a mains failure and POWER LAN starts

discharging batteries, after 2 minutes of discharging, the POSSIBLE AUTONOMY will be 15 minus 2=13

minutes.

• AUTHORIZED AUTONOMY

It is the maximum time allowed to discharge batteries in a discharge. If there is a mains failure and

POWER LAN changes to batteries, they will only discharge for a maximum time fixed by the value of

AUTHORIZED AUTONOMY although the batteries have more energy to keep on discharging. This

allows the maintenance of energy in the batteries in the case of any subsequent mains failure.
