EXP BUS MOUNTING TRAY

The EXP BUS mounting tray is the ultimate in quick build time savings. The tray comes Pre-punched, and pre-assembled with rocker switches prewired to the PC board. All the builder needs to do is to cut a single rectangular hole in the panel, connect the battery, alternator, and all of the load wires to the proper terminals on the EXP BUS2 PC board mounted in the chassis. 14V DC systems (not recommended for 28V aircraft) KITPLANE ELECTRICAL SYSTEM ON A PC BOARD:   • EXPBUS II--Second generation design   • Simplifies and organizes wiring   • Saves time, panel space, weight, and money   • Solid state "fuses" eliminate breakers   • Avionics master switch/starter cutout   • "Soft Start" extends landing light life   • Overvoltage protection   • Clearance delivery input for NavCom   • Dual bus option for backup battery   • A Complete Electrical System The EXPBUS 2 DC Load Center replaces all but one circuit breaker in most homebuilt aircraft, and includes the master switch, master relay, and the avionics master switch. The avionics output bus provides six protected circuits, and automatically shuts off when the starter is engaged. Three master bus outputs operate items such as panel lights, gyros and engine instruments. Switched outputs include the alternator field, Beacon/Strobe output, nav light output, aux fuel pump output, two landing light outputs, and two spares. All outputs are overload protected, eliminating the need for fuses or circuit breakers, and saving the labor of installing and wiring them up. Better Than Fuses EXPBUS II products are solid state protection devices that function very much like circuit breakers. When overloaded, these devices "blow," and the offending circuit safely shuts down. Unlike a fuse, the devices reset themselves, unharmed, after the load is removed for several seconds. Unlike breakers, there are no contacts to weld "on." Once tripped, these devices will remain "off" until the original load is completely removed for several seconds. These proven devices are annually used in hundreds of thousands of automobiles. Free Time For Sale Mounting requires drilling a few holes in the panel and bolting the unit in. Connect the battery cable directly to the terminal, and power leads from any devices such as radios, lights, gyros, and pumps to the proper switch or terminal on the PC board. Install one 40 amp breaker between the alternator and the PC board. All other outputs from the PC board are overload protected. There are no other fuses or circuit breakers to buy or install. Just think of the drilling, mounting, cutting, crimping, routing, labeling, and troubleshooting you will save (not to mention skinned knuckles and bleeding fingers). AND, while you save time, you will be getting a clean high-tech installation, with virtually no unfused wiring behind the panel. The switches can even be easily removed from the PC board, allowing the board to be remote mounted, anywhere in the aircraft. Advanced Features The Clearance delivery circuit allows one avionics bus output to be powered up with the master switch off--very handy at busy airports. The overvoltage protection circuit locks out the alternator field if the bus voltage ever exceeds 18 volts. The landing light outputs feature "soft start" circuits to greatly extend landing light bulb life. With the backup battery option, the two AUX outputs and one nav-com can automatically be powered by a standby power source in the event of a failure of the primary electrical system. The standby battery is automatically charged from the master bus during normal operation, eliminating the need for dual alternators in most cases. SPECIFICATIONS: Maximum Current Capacity - 40 Amps Bus Voltage - 14 Amps Keep-Alive Output (1, not switched) - 3 Amps Master Outputs (2, always on with master) - 1 Five Amp, 1 Seven Amp Instrument Light Output - 3 Amps AVIONICS MASTER OUTPUTS: (6) 1 Seven Amp Output 2 Five Amp Outputs 3 Three Amp Outputs SWITCHED OUTPUTS: Master Switch/Avionics Master Alternator Field - 5 amps Beacon/Strobe - 7 amps Nav Lights - 7 amps Aux. Pump - 7 amps LDG/Taxi - 9 amps LDG/Taxi - 9 amps Aux.Output (2) - 11 amps The above current ratings are based on "recommended" operating current. Traditional fuses and circuit breakers are rated in terms of "maximum" operating current. A 9 amp polyfuse circuit is roughly comparable to a 14 amp fuse or breaker. The above fuse sizes are a good match for most sport aircraft, your project will probably work well with this configuration. Size: 9.75" long by 4.625" deep by 1.875" tall. Weight 0.8 lbs. EXP BUS PRODUCTS EXP TRAY P/N 11-00430 $424.00 This is the ultimate quick build electrical system for the homebuilder. It includes the EXP2V load center PC board, with stylish rocker switches, mounted on an aluminum slide out tray. The tray, sized to fit nicely in the panel of most kitplanes, and mounts in a single rectangular cutout in the panel. Once installed, removing only 4 screws allows the entire tray assembly (and the entire electrical system) to easily slide out of the panel for access (there are no parts that will ever need service). The builder simply connects the battery and the alternator power leads to the PC board, and connects all of the loads to the various switches or terminals. The tray faceplate is powdercoated flat black, and silkscreened with standard nomenclature. Furnished with Rocker switches.   EXP2V P/N 11-00431 $299.00 This product is truly an electrical system on a PC board. Solid state "fuses" prevent circuit overloads, and replace circuit breakers. The electrical system offers 8 switched outputs for lights and pumps, two "master-bus" outputs for gyros and other accessories, an instrument output for powering engine instrumentation, an instrument lighting output, and six outputs that are switched on as an "avionics bus". This replaces a total of 19 fuses and circuit breakers. In addition to saving build time, and panel space, many advanced features are provided by the system. Furnished with Toggle switches.   IND 2 P/N 11-00432 $162.95 An indicator module for the Tray or EXP 2V. The annunciator illuminates a status light if any circuit in EXP system is tripped. Also features ammeter function, high and low voltage warning lights, and a dimmer.   BRKT 2 P/N 11-00433 $21.95 These mounting brackets save time when mounting the EXP2V. The pre-formed aluminum brackets provide a rigid mounting system to mount the toggle switch board, support the PC panel, and simplify installation. Not applicable to the EXP Tray.
