OPPF Series

"Not available from ""Dec/31/2024"".


[Not available in Japan]
Increased-capacity controller with built-in sensing function

Features

Support for both PWM light intensity control and strobe illumination

High-brightness settings with 1,000 intensity steps are possible with a PWM frequency of 100 kHz.
Lighting with up to 48 W total for 2 LAMP outputs can be connected. (Max. 30 W per channel)

High-brightness settings with 1,000 intensity steps are possible.
In addition, 1,000 steps with light emission widths from 10 μs to 9.99 ms at 10 μs intervals can be set.
The minimum settable light emission width is 1 μs (light emission width: 10 μs, intensity setting: 10%).
Light emission widths of 1 ms or less offer 3 times the brightness with 18 V overdrive output.
Lighting with up to 24 W for each LAMP output can be connected.

    • Approx. 6 V will be applied to drive the internal circuit of the lighting while it is not lit. The LEDs will not illuminate in this case.
    • The illumination state is not the same as that of with DC current even at 100% intensity illumination because the communication signals are superimposed.

　Connect lighting equipped with “FALUX sensing” to monitor brightness and temperature and to control feedback

Monitoring function

  • Accurately measure brightness not only during continuous illumination but also with ON/OFF control and strobe illumination.
  • This makes it possible to output an alarm when brightness decreases to a predetermined value.
  • Absolute brightness monitoring makes it possible to adjust for lighting instrumental errors.
  • In addition to brightness, measurement of internal temperatures is also possible.

Feedback (FB) control

  • FB control eliminates not only variations over long periods but also the need to perform periodic adjustments to the light intensity setting. By comparing the measured emission brightness with the lighting’s recorded reference brightness, FB control fine tunes the output voltage to match the standard brightness.
  • FB control also allows for compensation of reductions in brightness due to a voltage drop in the extension cable.
  • A signal is output as a feedback error when the upper or lower output voltage adjustment limit is reached.
  • Output voltage
    PWM mode: 11 to 18 VDC
    Strobe mode: 16 to 22 VDC
  • FB accuracy: ±1.5% or less (typ.)

The OPPF Series not only provides power for lighting from two conventional main line cables but also superimposes signals for communication with lighting. This allows for conventional use even with lighting that is not equipped with “FALUX sensing”.

External light intensity control

Using RS232 communication and external parallel input, centralized intensity control of all lamps is possible from the master device. Intensity control is possible by 0 to 5?V analog input to the individual lamps of each unit.

Multi-channel support

  • With 2 channels per unit, support for up to 8 channels is possible by linking (DIN mounting) 3 master and slave devices.
  • Communication between units is connector-less and uses infrared.
  • A setting copy function allows settings to be batch copied to all channels.
  • Connecting a single slave device or just a slave device is possible.

Bank registration of light intensity values

  • Pre-set intensity values can be configured and saved in the main unit, allowing for switching between intensity values with fewer inputs.
  • Up to 16 banks can be registered for each LAMP.
  • In addition to settings from the operation panel, switching is also possible through external parallel input and RS232 communication.

Surprisingly low price for provided functionality

  • Progressively expanding functionality to meet the diverse needs of customers.
  • Even with these functions, prices are kept lower than general-purpose controllers.
  • Lowest price range available for strobe-equipped devices.

Required 24 VDC power supply capacity to handle power consumption of lighting

Based on the total power consumption of the LED lighting to be connected, select a 24 VDC power source that offers more than the required capacity.

Note: When using in conjunction with other equipment, the characteristics of the other equipment will affect the power supply, so be sure to choose a power supply that has a sufficient margin (about twice as much) as that shown in the graph.
