W-MS24 range • Battery-charging and checking units

The 24 Vdc

W-MS24/150

and

W-MS24/40

battery chargers have

been designed specifically for voice evacuation systems. They are ba-

sed on microprocessor-driven devices and able to charge lead batteri-

es (back-up batteries connected to the voice evacuation system) and,

at the same time, to supply power to auxiliary equipment.

The W-MS24/40 and W-MS24/150 battery chargers meet in full the

requirements of EN54-4 (certificates nos.

0333-CPD-075382

and

0333-CPD-075381

), and ensure maximum charging currents of 6

and 12 A respectively. They have standard chassis for installing di-

rectly on 19” racks (height: 2 U).

The

W-MS24/4

charging unit, featuring low energy consumption, has

an aluminium cabinet covered in ABS. It ensures continuity of services

for your system, with an exceptionally good price/performance ratio.

The ease of installation and cabling of this unit, with two charging

outputs enabling a larger number of applications and the rated maxi-

mum battery-charging capacity not exceeding 55 Ah, are ideal featu-

res for using it with the PA8506-V integrated voice evacuation system

in medium-sized to small installations, always in accordance with the

applicable provisions of law.

The W-MS24/4 battery–charger, which complies in full with EN54-4

(certificate no.

0333-CPD-075192

), is suitable for installing directly

on a 19” rack (height: 3 U).

The

W-MS24/WF

power supply and battery-charging unit consists of

a switching type PSU with protection against short circuits and overlo-

ading and a card for managing controlled dynamic recharging of se-

aled lead batteries (tested regularly) and alarm outputs, a self-testing

function and LEDs for signalling 16 different system statuses.

The white-painted metal cabinet can also house the two batteries, pro-

viding a compact solution for easy and handy wall-mounting.

The W-MS24/WF, which complies with EN54-4 (certificate no.

0051-

CPD-0116

) must be connected to batteries not exceeding a rated

output of 27 Ah.
