DC Energy - Power Cabinet

CR ALPHA power cabinets are designed

for industrial applications: supplying PLCs,

control, relay and drive circuits, etc.

They are comprised of ALPHA modularrectifiers, a «maintenance-free» gas-recom-

bination lead battery and a supervisor. With the mains supply available, the rectifier

provides service flow and charges the battery. With the mains supply switched off,

the battery provides service flow with an autonomy that depends on its capacity.

Benefits

■ CR ALPHA power cabinets possess a wide

range of options for corresponding accurately

to your application.

■ With a 230 Vac -20% +15%, 50/60 Hz supply,

they provide direct voltage of 24,48,110,

120 ou 220Vdc, ±15%.

■ CR ALPHA power cabinets are equipped

with an electronic battery charger with a

power factor correction (PFC) which gives

the incorporated battery an optimal charge.

The supervisor, a protection and control unit

equipped with a microcontroller provides a

clear LED status display, summarizes faults

with 4 dry contacts and also displays voltage

and current, together with diagnostic

messages.

Fuses protect input and service power cir-

cuits as well as the battery.

A battery test checks that the battery is

capable of supplying the requisite load and

that the battery fuses are in correct condition.

This test is carried out automatically on a

cyclical basis and is particularly useful if your

battery is only used occasionally.
