The CS690 has best-in-class performance (with Anti-Slip Regulation traction control, next-generation ProDrive'" transmission, new CommandCenter." touchscreen display, and 500 hp from a new Final Tier IV 13.5 L engine) and uptime (with enhanced hydraulic oil service intervals and a dedicated auxiliary fan
A +12 VDC, or +5 VDC for 5 VDC output models, auxiliary fan
output is provided should forced-air cooling be required.
Depending on one's age and location, others less so--such as the John Howard Ladies' Auxiliary Fan
Club, the Sydney House of the Order of Perpetual Indulgence, the anti-uranium and land rights activist, 'Uncle' Kevin Buzzacott, or BUGA-UP, a group of well-organised after-dark graffitists who altered billboards that advertised cigarettes, beauty aids and McDonalds.
This model has a built-in active PFC function and a 12 V auxiliary fan
output with 5 V stand by.
Because of the layout of the laboratory, a rather tortuous path was required to connect the outlet of the nozzle chamber to the auxiliary fan
; this is illustrated schematically in Figure 6.
This is designed to provide more cooling for the engine, eliminating the need for an auxiliary fan
, which can increase emitted noise.
More user-friendly, the controls also allows the climate in the back to be adjusted thanks to an auxiliary fan
The auxiliary fan
generated high sound levels at some frequencies, which made some data points unusable.
Offering a typical efficiency of over 90 percent, ROAL Electronics' SFA160 Series of AC/DC power supplies deliver 160 W of regulated DC power with standard output variants of 5,12,24 and 48 V The 2" x 4" x 1" devices use an auxiliary fan
output of 12 V for system stand-by control voltage or to supply voltage for an external fan.
These include a new boom design with side stops; heavy reinforcements of the bogie; an autolube system; paint-on grip tread to reduce slips and falls during maintenance checks or repair work; a heavy duty auxiliary fan
motor; an isolated transverter; remote diagnostic pressure taps; a bolt-on battery box; raised air intake; improved fuel filter access; larger wear bars around the engine tub; and smaller, higher output batteries.
