ICS 3 & I3S: Inline Control System; Combined Strobe/Continuous Operation

The I3 and I3S Inline Controllers provide overdrive strobe and continuous operation to lights from a small package when larger, more versatile discrete controllers are not necessary.

Switching between continuous-on, gating on/off and strobe overdrive is seamless. The I3 and I3S employ Ai’s exclusive Adaptive OverdriveTM that optimizes strobe power regardless of input Pulse Width.

The I3 is a default-on device on power-up, whereas the I3S is a default-off device, requiring a trigger to illuminate
