Compact Universal 1- and 2- Channel

Universal 4-Channel LED Controllers with External Triggers and Voltage Monitoring

High_Precision Universal 4-Channel LED Controllers with External Triggers and 0.1mA Current Resolution

High-Current Universal 2-Channel LED Controllers with External Triggers and up to 2,000mA (CW) & 3,500mA (PWM) Output Current

Universal 12- and 16- Channel with 1mA Current Resolution

Mightex’s High-Precision 12- and 16- Channel Computer-Controlled Universal LED Drivers are designed to drive a broad range of LED light sources. Each unit comes with a powerful PC-based software with a user-friendly GUI, which enables users to drive LEDs without the need to write any code. In addition, a full-featured SDK is provided, in order for users to write their own software and to integrate Mightex’s LED drivers into their own systems. Furthermore, the drivers have a built-in protection feature, allowing users to limit LED driving current and voltage.

Each channel can be individually configured to work under one of the following two modes:

Normal Mode (or DC Mode): The output current is a constant, which can be adjusted (using software) from 0 mA to 1,000 mA, through the USB interface;

Strobe Mode: A Pulse-Width-Modulated (or PWM) periodic strobe pattern is output from the channel, which can be turned on by a software trigger. The strobe pattern may last indefinitely or for a preset number of cycles. The frequency of the PWM strobe can be up to 500Hz.

In addition, each channel can be individually DISABLED and ENABLED. No voltage or current is output from a DISABLED channel.

Specifications

1. Maximum Output Voltage is 3V less than the Power Supply Input Voltage. For instance, with a Power Supply Input Voltage of Vdc = 24V, the Maximum Output Voltage Vmax would be (Vdc- 3V) = 21V;

2. If the channel output voltage is Vd and the output current is Id, they must simultaneously satisfy: (1) Vd <= Vmax ; (2) Id <= Imax; and (3) Vd *Id <= Pmax; and

3. Each period of a PWM square wave comprises of ON time and OFF time, i.e. two (2) ‘steps’. The minimum value for each step is 1,000μs, and the minimum increment is 100μs.

4. Proper heat dissipation should be provided to the LED controller in customer’s system in order to prevent over-heating, which may lead to self-shutdown by the LED controller for protection purpose. In addition, the total output current of all channels should not exceed the capacity of the power adapter.

Specifications

Notes: 

1. Maximum Output Voltage is 0.5V less than the Power Supply Input Voltage. For instance, with a Power Supply Input Voltage of Vdc = 24V, the Maximum Output Voltage Vmax would be Vdc – 0.5V = 23.5V.
2. Each output channel can be individually configured to work in one of the following three (3) modes, controlled through a PC-based software with GUI. In all three modes, overdrive current limit can be set:
Normal: Constant current output at any value from 0mA to 1000mA with 12-bit resolution.
Trigger: External trigger signal could be used to turn on each individual channel, generating driving current with any user-defined waveform. Alternatively, each output channel can work under the “FOLLOWER” mode, in which the current output follows the waveform of the trigger input; and
Strobe: Internal Strobe Generator generates frequencies as high as 25KHz. The strobe signal (i.e. current levels, duty cycle and strobe frequency) can be set through software. For AA and AV series, the strobe signal can be a user-defined arbitrary waveform with 128 data points.
3. Arbitrary Waveform. Using the included application software or SDK or RS232 command set, users may define any arbitrary waveform using 128 data points.
4. Proper heat dissipation should be provided to the LED controller in the customer’s system in order to prevent over-heating, which may lead to self-shutdown by the LED controller for protection purpose. In addition, the total output current of all channels should not exceed the capacity of the power adapter.
5. 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.

Time Specification

What’s “Arbitrary Waveform”?
– For some LED controller models, one can use up to 128 pairs of [current (mA), duration (μs)] data points to define the ‘shape’ of the waveform. This will allow one to define an ‘Arbitrary Waveform’ for the LED driving current and consequently the LED’s optical output. Details see diagram below.

1mA Current Resolution Specifications

1. Maximum Output Voltage is 3V less than the Power Supply Input Voltage. For instance, with a Power Supply Input Voltage of Vdc = 24V, the Maximum Output Voltage Vmax would be Vdc- 3V = 21V;

2. If the channel output voltage is Vd and the output current is Id, they must simultaneously satisfy: (1) Vd <= Vmax ; (2) Id <= Imax; and (3) Vd * Id <= Pmax;

3. Each period of a PWM square wave comprises of ON time and OFF time, viz. two (2) ‘steps’. The minimum value for each step is 1,000μs, and the minimum increment is 100μs; and

4. Proper heat dissipation should be provided to the LED controller in the customer’s system in order to prevent over-heating, which may lead to self-shutdown by the LED controller for protection purpose. In addition, the total output current of all channels should not exceed the capacity of the power adapter.
