APPLICATION NOTES
1. Radio Frequency Interference (RFI): All solid-state speed controls generate annoying radio noise on the AM band. KB speed
controls contain, as standard, a high-gain RFI suppression filter which significantly reduces this interference.
2. Low End Set Point (Minimum speed): All 115 Volt input speed controls are factory set to 60 Volts AC output (±3 Volts), as
standard. All 230 Volt input speed controls are factory set to 120 Volts AC output (±6 Volts), as standard. All controls are factory
calibrated using an average responding AC voltmeter. Custom voltage settings are available.
3. Motor Suitability: Motors must be loaded to near full capacity with the appropriate fan blade in order to achieve proper speed
control. Generally, motor suitability is established by determining motor speed as a function of applied voltage. A motor is
determined as suitable if it changes speed linearly over a wide range of voltage.
It is required that all motors contain a built-in thermal overload protector when used with solid-state speed controls.
4. 230 & 277 VAC Controls: To achieve maximum reliability, all 230 VAC controls contain snubber networks that utilize Y-Type
capacitors and flame-proof resistors. In addition, all 277 VAC controls contain MOV Transient Suppression.
5. Temperature Test: The non-sinusoidal output voltage of a solid-state speed control may increase motor heating. Therefore, it is
necessary that a temperature test be performed to ensure that the motor is operating within manufacturer’s specifications.
6. Leads: All leads are approximately 6” (15 cm) long and stripped 1/2” (1.25 cm). Custom lead lengths, colors, and terminations
also available.
