”Ultra IBEC” Features
Eliminates the need for a separate ignition battery and mechanical on/off switch.
Compatible with the power requirements of single and twin cylinder model CDI ignition
modules via jumper selectable 5V, 5.3V, 6V and 6.6V voltage outputs.
Enhanced flexibility and safety via transmitter controlled on/off control of CDI ignition
power from a spare receiver auxiliary channel.
Tech-Aero exclusive 4 stage filtering blocks 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 2
nd
order common mode LC power lead filter.
o
Filter stage 3:
Three power filter capacitors combine to provide over twice the
capacity of others, enhancing 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 any battery technology commonly used for
radio control use, with a usable input voltage range from 4.8V to 13V.
Bright 3mm LED CDI power on/off indicator.
High reliability Surface Mount components reduce weight to only 0.6 oz and size to 1” x
1 ¾”.
Heavy duty 22 gauge twisted wire power extensions.
