1. Technical description.
1.1. General description.
The RUPS812T buffer power supply unit is designed for uninterrupted power supply of up to 8 HD cameras
requiring stabilized voltage of 12V DC (+/- 15%). The PSU provides voltage of U=13,8V DC.Current efficiency:
Output current 8A + 1A battery charge.
Total device current + battery: 9A max.
In case of power decay, a battery back-up is activated immediately. The PSU is fitted with 8 outputs
protected independently with melting fuse 1A. The power supply is fitted with the ALARM output of collective
failure. In case of failure, relay contacts are switched automatically, which is accompanied by acoustic and optical
indication (the corresponding led goes on). The power supply construction is based on the switch mode PSU with
high energy efficiency and is located in an enclosure adapted for mounting in standard RACK 19” cabinets.

2. Installation.
2.1. Requirements.
The PSU RACK shall be mounted by a qualified installer with appropriate permissions and qualifications for
230V/AC installations and low-voltage installations (required and necessary for a given country). The device shall
be mounted in confined spaces, according to the environment class II, with normal air humidity (RH=90% max.
without condensation) and the temperature from -10°C do +45°C.
During normal operation the total current consumption of the receivers cannot exceed
I=8A. Maximum battery charging current is: 1A.
Total device current + battery: 9A max.
As the PSU is designed for a continuous operation and is not equipped with a power-switch, therefore an
appropriate overload protection shall be guaranteed in the power supply circuit. Moreover, the user shall be
informed about the method of unplugging (usually through assigning an appropriate fuse in the fuse-box). The
electrical system shall follow valid standards and regulations.
2.2. Installation procedure.
1. Before installation, cut off the voltage in the 230V power-supply circuit.
2. Mount the power supply in a RACK 19" cabinet as shown below:
- Mount M6 cage nuts
- Secure the enclosure with 4xM6 screws
3. Connect the receivers’ cables to the terminals AUX1...AUX8.
4. If needed, the following technical connections can be made:
- ALARM –technical output of collective failure
5. Connect the battery to the +BAT- terminals:
- battery output (+): terminal BAT+
- battery output (-): terminal BAT-
6. Connect the ~230V AC power cord with the IEC C13 plug (included) to the 230V AC power supply and turn on the
power (~230V).
7. Check the PSU operation indicator.
3. Operating status indication.
3.1. LED indication.
The PSU has 13 LED lights at the front panel:
GREEN LED:
on –the PSU is supplied with 230V AC
off –no 230V AC supply
GREEN LED:
on –DC voltage at the output of the switch mode PSU
off –no DC voltage at the output of the switch mode PSU
RED LED:
on –failure

off –no failure
RED LED:
ON –too high temperature of the switch mode power supply
(>70°C)
OFF –standard temperature of the switch mode power supply
RED LED:
on –battery voltage <11,5V
off –battery voltage >11,5V
GREEN LED:
on –DC voltage in the AUX1…AUX8 output
off –no DC voltage in the AUX1…AUX8 output
3.2. Technical output.
The power supply is fitted with the ALARM output of collective failure (relay type). A collective failure can
be triggered by the following events:
- 230V AC mains power failure
- Melting fuse activation F1÷F8
- Failure of the switch mode power supply
- Too high temperature of the switch mode power supply (>70°C)
- Low battery voltage (<11,5V)
Fig. 4. Electrical diagram of the ALARM collective output of failure.
CAUTION! In Fig.4 the set of contacts shows a potential-free status of the relay, which
corresponds to power supply failure.
3.3. Acoustic indication.
A collective failure is indicated by the piezoelectric indicator, 1 beep every second. The acoustic indication
can be turned off by changing the ON / OFF position of the switch .
switch in the up position, indication ON
switch in the down position, indication OFF

4. Operation and use.
4.1. Overload or short circuit of the PSU output.
The AUX1 ÷ AUX8 power supply outputs are protected against short circuit by melting fuses; in the case of
fuse failure, it should be replaced with a fuse of the same type.
4.2. Battery-assisted operation.
In case of a main power outage, the device is immediately switched into a battery-assisted operation.
The PSU is equipped with the discharged battery disconnection system. During
the battery-assisted operation, reducing voltage below 9,5V at the battery terminals will
cause battery disconnection.
4.3. Maintenance.
Any and all maintenance operations may be performed following the disconnection of the PSU from the
power supply network. The PSU does not require performing any specific maintenance measures. In case of fuse
replacement, use a replacement of the same parameters.
