1. Technical description.

1.1. General description.

The buffer power supply RUPS824P is used for uninterrupted supply of devices requiring stabilized voltage

of 24V DC (+/- 15%). The PSU supplies voltage of U=27,6V DC and total current capacity of:

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 polymer fuses PTC 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 cameras 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 in series 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

www.pulsar.pl RUPS824P RACK POWER

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 <23V

off –battery voltage >23V

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

- Activation of the polymer fuse PTC

- Failure of the switch mode power supply

- Too high temperature of the switch mode power supply (>70°C)

- Low battery voltage (<23V)

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 with polymer fuses PTC. If a

fuse-assisted protection has been chosen, replace the fuse (of the same parameters) in case of a failure.

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 19V 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.
