Mightex BLS-1000-2 and BLS-3000-2 LED controllers are designed for driving Mightex LED sources. The controllers have two operation modes:

Manual Mode: the output current can be controlled by manually turning the knobs; or
Trigger Mode: the output current can be controlled via an external analog input signal between 0-5V.

The control mode is selected with a slide switch on the front panel, and the factory default is “Manual” mode. BLS-1000-2 and BLS-3000-2 provide Maximum Current Selection DIP switches on the rear panel, which allow the user to set the maximum output current of the channel to 500/750/1,000mA for BLS-1000-2, and 1,000/2,000/3,000mA for BLS-3000-2, respectively. The factory default is set to 500mA for BLS-1000-2 and 1,000mA for BLS-3000-2, respectively.

When the controller is set to “Trigger” mode, the output current is fully controlled by the input analog signal (0-5V).

  • Dual Control Modes: manual or analog voltage-input controlled
  • High modulation speed – up to 100kHz
  • BNC connectors for analog voltage inputs
  • Simple, tool-free connections
  • Capable of driving variable loads
  • Optogenetics
  • Fluorescence excitation
  • Microscopy
  • Testing instruments
  • Medical instruments

Note: *When Vforward of LED load is more than 8V, 24V DC input might be used; ** The input current should be greater than the combined output current of the two channels; ***External analog voltage source should have 8+ mA of current driving capability.**** It is not recommended to mix Type-A/J LEDs with Type-B LEDs on a single unit of this controller. Please operate Type-A/J LED’s on one unit and Type-B LEDs on another.

Front and Rear Panels:

The Front Panel has a power switch and a power indicator. Each channel has its own slide switch (for selecting Manual or Trigger mode) and a turning knob (for adjusting output current).

The Rear Panel has a DC input plug. Each channel has a BNC connector for external trigger/analog voltage signal, a two-pin LED aero connector. For BLS-1000-2 and BLS-3000-2 only, each channel has a pair of DIP switches to set the maximum current.
