SmartFan Aurora DC Motor Speed ControlOperation/Installation Manual
FEATURES:
Input Power:
Aurora can accept power from an AC (12 to 48V) or DC (10 to 72V, 50/60 Hz) source. Aurora can supply up to 6.0 Amps to the motor load with a maximum 55 C operating temperature.
Input Power Fuse:
A 10.0 Amp input power fuse is provided to protect the Aurora from over-current conditions.
Inrush Current:
The Aurora utilizes a passive inrush limiter circuit to control initial contact current.
Fan Soft Start:
At the application of power, the Multi-SD output voltage starts at 0 VDC. Then, over a period of approximately 5 seconds the fan voltage is modulated from 0 VDC to full voltage and then temperature (or PWM) based control begins.
Fan Soft Start:
At the application of power, the firmware in Aurora limits the maximum available output voltage to 0 VDC. Then, over a period of approximately 2 seconds the available voltage is raised to 100%.
Motor Speed Control:
Motor speed is varied by adjusting the voltage applied to the motor. Voltage adjustment is accomplished with a current mode, buck type control circuit. The motor voltage range is 0-12 VDC for 12 VDC motors, 0-24 for 24 VDC motors and 0-48 VDC for 48 VDC motors.
Cycle by cycle 8 Amp over current protection with 6 Amp power limiting feedback control.Off-Input:
Connection of OFF to COM terminals of TB2 will set the maximum available voltage to 0 VDC.Specialized Configurations of the Aurora:
The following parameters can be specialized by CRI through software and/or component values changes:
- Special factory configuration option available to set:
