Heat Resistant Design

Heat Resistant Design

N/A The B1793 TITAN® Series AC blower has a proprietary engineered aluminum enclosure that acts as a heat sink to dissipate heat more effectively, resulting in a cooler surface temperature and reduced wear on the internal components. This unique patent pending enclosure design ensures added thermal protection and greater long-term reliability.

Soft Start Operation

Soft Start Operation

N/A The B1793 TITAN® Series AC Blower includes "soft start" operation whereby startup occurs gradually until the desired speed is achieved. This gradual speed increase reduces electrical surges that result from high inrush current and enables the blower to operate quieter and to achieve a longer operating life than competitive cooling products.

Universal Dual PWM Speed Controls

Universal Dual PWM Speed Controls

N/A The B1793 TITAN® Series AC Blower includes a built-in dual PWM speed control system designed to take advantage of different application circuit designs. The user can select from either DC voltage signal control (VPWM) isolated operation or pulse signal control (PPWM) isolated operation by connecting the appropriate wires. The blower’s maximum speed can also be adjusted via an on-board variable speed resistor that is easily accessed on the external housing.

Added Performance

Added Performance

N/A The B1793 TITAN® Series AC Blower also includes an isolated open collector tachometer (frequency generator) that monitors the running speed and locked rotor protection to ensure that the blower will automatically restart if the motor is released from a locked condition.

The B1793 TITAN® Series AC Blower is an ideal cooling system for a variety of applications including medical equipment, automotive, industrial products, and other applications that require a compact blower with high performance and long-term reliability.

Tachometer (FG) - Open Collector Output

Tachometer (FG) - Open Collector Output

N/A The Frequency Generator (Tachometer) (FG) Control is an open collector output type that provides a square wave signal if this open collector output is connected to a "PULL UP" resistor and is powered by the power supply voltage which is compatible with the input of the reading device (such as TTL input of the computer, etc.). The maximum collector voltage may be up to 48 VDC and the maximum collector current is 10 mA. The power supply of the reading device must have the same ground potential as the blower. The Frequency Generator Control is an external YELLOW wire.

Variable Resistor for Maximum Speed Adjustment

Variable Resistor for Maximum Speed Adjustment

N/A The blower housing includes a variable resistor that is located near the wire exit area and is covered by a removable black rubber plug. The variable resistor can be turned gently with a small screw driver in order to adjust the maximum speed limit. The blower is set to its maximum speed of 13000 RPM and adjustment to alternate maximum speed can be set by the available external control inputs.

PWM Speed Control

PPWM

N/A Pulse Width Modulation (PWM)
Pulse Height: H = 5~10 V
L < 0.5 V
PWM Frequency Range 30 Hz~30 KHz

PWM Speed Control

N/A The Pulse Width Modulation Signal (PPWM) Control adjusts the speed by applying a pulse width modulated signal whose frequency may be in the range of 30 Hz to 30 KHz and the maximum pulse height "HIGH" may be from 5 V to 10 V. The maximum pulse height "LOW" is 0.5 V. The blower speed will vary linearly and is proportional to the % change of the Duty Cycle value, corresponding to the same % change of the maximum speed. The PPWM Control Input is applied to the external BLUE wire.

VPWM Speed Control

VPWM

N/A DC Voltage Signal Control Input
0~5 VDC input -->Control 0~100% speed.
VPWM - Input Signal of 10 V PWM pulse height.
0~50% modulation -->Control 0~100% speed.

VPWM Speed Control

N/A The DC Voltage Signal (VPWM) Control adjusts the speed by applying an external DC Voltage signal. This voltage input "Vin" may have any value from 0.3 V to 5 VDC (at Vin=0, the blower stops). The blower speed will vary linearly and is proportional to the % change of the "Vin" value, corresponding to the same % change of the maximum speed. The VPWM Control is applied to the external WHITE wire.

Test Conditions

Vibration

N/A In minimum packaging condition, blower motor withstands 0.2 mm movement of 55 Hz vibration for 30 minutes each towards: up-down, right-left and back-forth.

Drop Test

N/A In minimum packaging condition, motor withstands each one-drop of three faces from 30 cm distance high onto wooden board of 10 mm thickness.

Life Expectancy

N/A Minimum 50,000 hrs at 25 ºC, 65% R.H. at rated voltage. The life is defined as the time duration until the blower motor speed is decreased more than 30% compared to its initial speed.

Protection

Locked Rotor Protection

N/A Blower will automatically restart in maximum 4 seconds after motor is released from locked condition.

Polarity Protection

N/A For DC inputs - No damage if positive and negative leads are reversed under maximum operating voltage conditions.
