The PX319 driver is designed to control LEDs. It has voltage of 12 - 48 V DC and a maximum

current-carrying capacity of 2 A. It is possible to set the driver output current according to the

parameters of receivers LED.

PX319 can be controlled by the DMX signal (the device has a built-in DMX-512 receiver) or it can

work independently. DMX address is set manually via a DIP switch on the housing. The user also

has the ability to set one of the eight levels of brightness with which the LEDs will be triggered in

the absence of a DMX signal.

1. GENERAL DESCRIPTION

2. SAFETY CONDITIONS

PX319 is a device powered with safe voltage of 12 - 48 V DC; however, you should at all times

obey the safety conditions. It is necessary to observe the following rules:

1. The device can be connected to 12 - 48 V DC (stabilised voltage) with current-carrying capacity

compatible with technical data.

2. All the conductors should be protected against mechanical and thermal damage.

3. In case of damage to a conductor, it should be replaced with a conductor of the same technical

parameters.

4. Connection of DMX signal can be made with a shielded conductor only.

5. All repairs, connecting and disconnecting of cables can only be made with cut off power supply.

6. The device should be strictly protected against contact with water and other liquids.

7. All sudden shocks, particularly dropping, should be avoided.

8. The device cannot be turned on in places with humidity exceeding 90%.

9. The device cannot be used in places with temperature lower than +2°C or higher than +40°C.

10. Clean with damp cloth only.

PX319 allows for setting the address DMX. The address is set in a binary code using the “DIP

switch”. Below are some examples of setting the address DMX. Nine first “DIP switches” are

responsible for the address; the tenth switch is responsible for activating the “smooth” function.

The white colour is a switch. It is ON when set in

the upper position, and OFF when set in the lower

position.

The PX319 driver is equipped with an additional DIP-Switch which allows you to set the No Signal

function, responding to the driver action when it does not receive the DMX signal.

With this switch, it is possible to set one of 4 brightness levels. The brightness increases from the

smallest (zero) to the maximum one, in accordance with the binary markings on the “DIP switch”.

Below are brightness levels and the corresponding switch settings.

With the smooth function enabled, transitions between successive control signal values are

smoothed, allowing for smooth changes in the brightness of the connected LEDs. This prevents

the light “vibration” effect that usually occurs in lighting systems when light intensity is being

changed.

The “smooth” function and DMX address set to 1.

The PX319 driver is equipped with a function to set the output current controlling linear LED

modules. Depending on the number of modules connected to the device, it is necessary to select

the control current by choosing a resistor with the appropriate resistance. The table below shows

the correct selection of resistors:

In the absence of any connection between resistor and PX319 driver, it will operate with adjusted

Example of the resistor identification:

Irrelevant

You can connect an external 4K7 thermistor to the driver. As the temperature exceeds 70ºC, the

driver starts to limit output power. Once a 90ºC threshold is exceeded, complete shut off is carried

out.

If no NTC thermistor has been connected: 100% of power available at the output

NTC thermistor short circuit: 0% of power available at the output

6.1. TEMPERATURE CONTROL

PX319 must be connected to DMX line in series. This means that DMX IN terminals in the device

must be provided with the driving cable, and then from DMX OUT connector the driving cable

must be provided to other DMX receivers.

If PX319 is the last device in DMX line, DMX Out terminals must be provided with the terminator –

resistor of 120 Ohm between pins “+” and “-”.
