1. Technical description.

1.1. General description.

The R1624Tpower supply unit is designed for uninterrupted power supply of up to 16 HD cameras requiring

stabilized voltage of 24V DC with the total current efficiency of 8A.The output voltage adjustment range is adjusted

via a potentiometer within the range of 20V÷26V DC. The PSU is fitted with 16 outputs protected independently

with melting fuse 0,5A. 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.

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...AUX16.

4. If needed, the following technical connections can be made:

- ALARM –technical output of collective failure

5. Connect the ~230V AC power cord with the IEC C13 plug (included) to the 230V AC power supply and turn on the

power (~230V).

6. In the case of an unsafe voltage supply with frequent voltage drops in effective resistance of receiver supply cables

can occur, it is possible to adjust the output voltage using the potentiometer (20V÷26V DC) at the front panel of the power

supply.

7. Check the PSU operation indicator.

3. Operating status indication.

3.1. LED indication.

The PSU has 20 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

GREEN LED:

on –DC voltage in the AUX1…AUX16 output

off –no DC voltage in the AUX1…AUX16 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÷F16

- Failure of the switch mode power supply

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

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 ÷ AUX16 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. 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.

WEEE LABEL

Waste electrical and electronic equipment must not be disposed of with normal household

waste. According to the European Union WEEE Directive, waste electrical and electronic

equipment should be disposed of separately from normal household waste.
