2. INSTALL SCHOTTKY DIODE (Refer to Figure 7)
The Cyclone uses an internal Schottky diode, while the Atom
does not. For added performance, it is recommended that an
external Schottky diode be installed on all motors, and must be
used with the Atom. This will increase the efficiency and reduce
the operating temperature of the speed control.
Solder the lead closest to the silver stripe on the Schottky to
the POSITIVE (+) motor tab. Solder the lead opposite the silver
stripe on the Schottky to the NEGATIVE (–) motor tab.
NOTE: If installed backwards, a Schottky diode will be destroyed. The
body of a bad diode will normally crack open. Replace only with
Schottky diodes that have a minimum rating of 35 volts DC/8 amps.
Schottky diodes are available in Novak Kit #5640, and 0.1
µ
F capaci-
tors in Novak Kit #5620.
3. INSTALL POWER CAPACITOR
Included with the Cyclone & Atom is a high-frequency, low-
impedance power capacitor, that will improve the ESC’s
performance by dropping the operating temperature 10-15
°
F.
It is necessary to install this power capacitor to dissipate noise
and smooth voltage spikes generated by the ESC’s ultra-fast
switching circuit, especially in heavy-load applications, and
when ambient temperature exceeds 85
°
F. Extra power
capacitors are available in Novak Kit #5670.
NOTE: Failure to use the power capacitor may result in damage to
the speed control and will void the warranty.
As the Cyclone & Atom speed controls were designed to allow
greater flexibility for the user, they come with the power
capacitor and power wires unattached. This allows you to
install the power capacitor and position the power wires
according to your individual car set-up.
The power capacitor is polarized with the side of the negative
