Tech-Aero - Ignition Battery Eliminator Circuits for CDI ignitions ( IBEC) - includes opto kill switch amongst its great features.

Every Tech-Aero Ultra IBEC HV is assembled at our US based electronics assembly house with the highest of quality standards

(remember this saves you both the cost of an additional ignition battery as well as a seperate opto kill switch) also means there is one less battery to charge and less weight in the airframe.

”Ultra IBEC HV” Features

Eliminates the need for a separate ignition battery and mechanical on/off ignition switch. Compatible with the power requirements of single and multi-cylinder model CDI ignition

modules via jumper selectable 5.9V, 6.3V, 7.3V and 8V voltage outputs. Enhanced flexibility and safety via transmitter control of CDI ignition power from a

spare receiver auxiliary channel.

Tech-Aero exclusive 4 stage filtering that includes signal lead optical isolation removes interference from CDI ignition noise in the wiring path to the receiver, permitting use with 2.4 GHz Spread Spectrum and 72 MHz FM radio receivers. *

o Filter stages 1 & 2: An advanced 2nd order common mode LC power lead filter.

o Filter stage 3: Triple power filter capacitors form a low pass filter and enhance peak impulse current delivery to the CDI module.

o Filter stage 4: An optical isolator circuit prevents any stray noise from feeding back into sensitive receiver electronics via the signal lead.

A high precision, very low dropout power regulator design further assures power receiver bus isolation with superior performance during peak current demand.

One IBEC model fits all: compatible with all battery chemistries commonly used for radio control use, with a practical input voltage range from 6V to 8.4V. A 2S LiPo / LiIon receiver battery or equivalent supply voltage is recommended overall and is required for 7.3V and 8V operation. 2S LiFe and 5S NiCad /NiMh batteries are compatible with the 5.9V or 6.3V output settings. 4 cell NiCad / NiMh batteries can be used with some legacy CDI’s, but will not be voltage regulated at the IBEC output.
