- Dimmer switched off by factory Needs to be enabled via RS-232.
- Longer flash times can be set via RS-232
- Input voltages above 5 V will destroy the trigger input circuit!
- for MBJ connecting cable and MBJ LED light (-x) without integrated controller
- Do NOT connect to the external ground of the power supply or the ground of the trigger signal! This might destroy connected lights or devices.
Operating modes

STEADY| Continuous light, LED always on| –
AUTO1)| LED-output follows the trigger| LED-output follows the trigger
FLASH| Manual set-up for flash, delay and duration (via RS-232 only)| Flash-
on-trigger with set flash duration via rotary switches or RS-2322)
OFF| LED output switched off
- The CTR-50 factory setting of the operation mode is AUTO. Other operating modes are selectable via the RS-232 interface.
- The CTR-51 factory setting of the operation mode is FLASH. Other operating modes are selectable via the RS-232 interface.
Detection of the light source
After the CTR is powered on, it remains in detection mode until an LED
illumination has been connected and detected.
Afterwards the CTR starts operation.
RS-232
The serial interface allows changing the operation mode and set-up of
individual timings and currents. The control commands are described in a
separate RS-232 manual which can be found at:
www.mbj-imaging.com/en/products/led-controller.
Rotary Switches
Use the rotary switches to set-up the allowed current for the connected LED.
Please check the LED light manufacturer’s manual to make sure not to exceed
the maximum LED current.

- LED current less than 100 mA may cause LED light flickering
- The flash energy is provided by a capacitor and requires sufficient time for recharging. The flash energy (flash frequency flash duration current) is limited to 1A. E.g.: 100 flashes/s 100µs 30A = 0.3A
- The higher the current and the shorter the cycle time, the greater the latency can be.
Application Samples for CTR controller
Steady light Steady light with brightness control (CTR-50
only)
24 VDC triggered light , Common emitter, sinking (NPN) Inverted strobe signal
5 V
triggered light, Common collector, sourcing (PNP)
Mechanical Integration
The CTR controllers are supplied with screwable plug-contacts for power supply, control signals, RS-232 interface and the LED light. The controller is made for top hat rail mounting, a clip locks the unit to the top hat rail.
Safety Notes
Before working with this unit, read the warning and application instructions carefully and completely.
- The device is designed for indoor use only.
- Health – The device must be disconnected from the power source before the installation and/or maintenance can start. The device must not be used when a failure may cause a personal injury.
- Electricity – The housing is electrically isolated from the ground of the power supply. Exceeding the permissible operating voltage or exceeding the maximum allowed switching current per channel can lead to the destruction of the device or to a significant shortening of the lifetime of the connected LED lighting module.
- Mechanical integration – The controller is made for top hat rail mounting. A clip can be used to lock the unit to the top hat rail. For optimal heat flow a left/right distance of 10mm to next unit is recommended.
