Uninterruptible DC-Power Supply

EA-UPS 712-12B

This uninterruptible DC-power supply is designed to

feed low voltage equipment which must continue oper-

ating in event of a mains supply failure as i.e. SPS-

controls, alarm equipment, supervision equipment,

telecommunication equipment etc. The unit is supplied

complete with a maintenance free, sealed accumulator

with an expected operational life of 3 to 5 years. Should

the unit run in emergency operation for a longer period

so that the danger of the batteries being damaged by

being run down arises then the unit will be automatically

switched off.

Technical description:

The unit consists of a power supply / charging unit. On

mains operation the battery is kept fully charged and the

load is supplied by the power supply. In the event of a

mains failure the battery supplies the load without

interruption.

Should the unit run in emergency operation for a longer

period so that the danger of the batteries being dam-

aged by being run down arises then the unit will be

automatically switched off. This shut down is caused at

a battery capacity of approx. 20%.

Installation

Before taking the unit into operation it is necessary to

inspect the housing, the controls etc. for signs of

physical damage. Save all packing materials until the

inspection is completed. If damage is found, notify the

carriers immediately. Our authorised representative

also should be notified. If any physical damage has

been found, the equipment should not be connected to

the mains.

WARNING: DO NOT OPEN THE UNIT BEFORE YOU

ARE SURE, THAT THE POWER CABLE IS

DISCONNECTED FROM THE MAINS VOLTAGE !

Servicing, repairs or calibrations should only be carried

out by trained engineers. The unit may only be

operated using a properly wired and grounded mains

plug as the grounding of the unit follows via the earth

wire of the power cable. The unit must be operated only

on the voltage stipulated on the type plate. If it is

necessary to change the fuse, it is imperative that it only

be replaced by one of same value and physical

dimensions as the original supplied fuse. The unit must

be disconnected from the mains whilst replacing the

fuse.

The battery is protected with a fuse on the rear of the

unit. This fuse is removed when the unit is delivered to

protect the battery.

The load must be connected to the + and – output

terminals.

Operation

Before you switch on the first time the unit, be aware,

that the output voltage of 12V is already available on the

output terminals when the push-button “Output-ON”

has been activated. Therefore be careful when

connecting the load.

When the battery unit is connected or the mains is

supplied the output can be switched on with the internal

or external push-button “Output-ON”

Now the load is supplied with an output voltage of nom.

12V and a max. current of 12A.

The batteries are connected in parallel to the output.

The LED “Output ON” is lit, when the voltage is on the

output terminals.

On mains failure the load is supplied from the batteries

without any interruption. When the mains returns the

load is supplied from the power-supply and the batter-

ies are charged.

In case time of the mains failure is so long that the

battery voltage becomes too low, the output will be

switched off to prevent the batteries to be completely

discharged.

The batteries are charged as soon the mains voltage

returns. The output must be switched on manual with

the switch “Output ON”. The battery will be charged

immediately after mains return.

In case the DIP-switch "Automatic RESET" (factory set

to "0") is set to "I", the output voltage will be available

immediately after mains return.

Two isolated relay contacts are supplied for external

alarm of "Charging voltage LOW" and "Battery voltage

LOW".

"Charging voltage LOW" is activated below 12,5V (i.e.

mains failure or defective.

"Battery voltage LOW" is activated below 11,5V

(battery capacity below 20%). The capacity of these

contacts is 60V/1A. These alerts are also indicated via

LEDs on the front.
