Note: D2Flex is as discontinued product (25 May 2011)

D2FLEX V2.0 PWM Driver/Controller:

PWM dimming driver (Direct Drive, NO current regulation). PWM frequency ~800Hz.

Maximum input voltage 24V, nominal minimum input voltage 2.7V.

Ships with UI-uni firmware (see below).

Non-volatile storage of brightness level.

Maximum drive current 6A (upgraded FET compared to V1.x, capable of handle P7 or MC-E type LEDs.

uController based design.

Momentary action switch controls User Interface (UI).

UI-UNI2 firmware

Draws ~100uA in sleep mode.

Temperature monitoring of driver board. If closely coupled with the light's body, it can be user configured to force the current output to reduce. Optional trip points of 50, 60, 70, 80, 90C or off.

Protected against reverse polarity connection, output open circuit protected.

Board is 0.80" in diameter.

(UI-UNI2 new Firmware):

The new UI-UNI2 firmware unifies the previous UIF, UIP and UIB2 firmware into a single release. This has the advantage of providing the user with a choice of 3 of the most popular TaskLED UI's in a single product. The user can configure via the menu system which of the UI's is active at any time. UIF and UIP also inherit the temperature sensing capability of UIB2.

Unification of UIF/UIP firmware with the UIB2 firmware.

Temperature monitoring of driver board. If closely coupled with the light's body, it can be user configured to force the current output to reduce. Optional trip points of 50, 60, 70, 80, 90C or off.

UIB2: Bike optimized, Choice of 2 level (duomode), 3 level (trimode or threemode) or 5 level (multimode) operating modes.

UIF: 8 level dimming, fixed lighting use optimized..

UIP: 5 level dimming, flashlight use optimized.

User selectable optional Force level (the level that the light will always turn back on).

Optional superlock that requires multiple clicks to turn the light on - prevents friends turning your light on accidentally.

UIB2: User selectable Strobe mode or Constant mode for day/dusk or night use.
