The
2 Place Trim Mixer is a solid-state SMT equipment designed to replace
the traditional mechanical relays earlier used for two pilots to operate the aircraft's
trim system while adding the advantages of logic functions found in electronic
equipment.
The mixer incorporates MOSFET
(Metal Oxide Silicon Field Effect Transistor)
transistors for switching the high current with no moving parts and no electrical
arc to prevent fuel fumes
ignition.
A typical
Trim System is composed of the following elements:
A mixer unit, the
2 Place Trim Mixer, and
Two DC trim motors
(such as the MAC Servo with or w/o connections to position indicator)
Harnesses
An SPST switch
(option)
which are not included & should be provided by the customer
A key feature of the 2 Place
Trim Mixer is the prevention of a conflict between two opposite inputs (eg.
"UP" by the pilot, and "DOWN" by the copilot). Once an input is established
by one of the crew, another input is ignored. An additional switch (option)
enables the pilot to "Disable" the copilot from inputting any command to the
trim motors.
The 2 Place Trim Mixer is
enclosed in an aluminum enclosure for EMI/RFI protection and for easy installation
onto the aircraft. |
