Controller with 4 operating modes (-s)

Produktportfolio von MBJ Imaging

Integrated controller (-s)

All MBJ standard lights are available with integrated 4-mode controller - one of the most popular and customer appreciated features in our portfolio.

What does "integrated" mean?
The -s controller is installed directly in the housing to save space and enables slim installation dimensions of the lighting. Commissioning via plug'n'play is quick and easy, and with no less than four operating modes, the -s Controller is a real all-rounder.

Know-How about the integrated controller

Operating modes:

  • Steady light
  • Brightness-controlled continuous light
  • Switched continuous light (triggered)
  • Flash mode

Cable controller (-s)

The popular -s controller also as a cable-integrated variant, e.g. to retrofit standard lighting without an internal controller (-x).

Know-How cable controller

  • 4 operating modes: 24 V steady light, PWM brightness control, triggered steady light or flashed light
  • M8 4-pin or M12 4-pin female connector to light
  • Approx. 0.5 m cable, controller housing, 1.5 m cable with open wire
  • Cable controller version as: 150 mA, 250 mA, 300 mA, 450 mA, 600 mA, 750 mA, 900 mA, 1200 mA, 1500 mA

RS232-USB Adapter Cable for CTR-50/51 control

Quick and easy set-up of CTR-50/51

The adapter cable makes it easier to set up the CTR-50 and CTR-51 controller series via RS-232.
Simply connect the three open cable ends to the RS-232 port of the controller. The USB-to-RS232 converter is then plugged into the USB port of the computer - the controller can now be adapted to your requirements using serial communication software (e.g. HTerm).

  •     USB 2.0 Type-A plug
  •     Serial RS-232 with open cable ends (3 pin)
  •     1m length
