ThermaPro-V Technology

You can count on TPV to reach your optimal cooling point with minimal noise - without adding on to your system. Now you can design-in Voltage Regulated, Programmable, Thermally Speed
Controlled brushless DC fans for completely reliable cooling.

Thermal Speed Controlled, Programmable, Voltage Regulated DC Fans & Blowers

ThermaPro-V capabilities are achieved through the use of a patented circuit design. A small voltage regulator is placed in series with the motor windings. An additional lead from the control leg of the voltage regulator is brought out of the fan to enable the customer to adjust the voltage to the windings and control the speed of the fan.

Thermal Speed Control

With TPV's closed loop Thermal Speed Control capability, a small thermistor is used to program the fans voltage regulator to change airflow automatically as a function of temperature. It automatically provides needed cooling in extreme environments and a minimum of noise and power consumption at all times. This results in complete efficiency for your system. And, with two power leads, plus a control and return lead (zip-cord) to the PTC thermistor, there's no change of system shut-down.

Should the sensor fail open, the fan reaches maximum airflow, avoiding any possible damage to sensitive equipment. That means complete reliability for your system.

Programability

You can now specify a single fan to cover a broad range of airflow needs. TPV Programability lets you easily control the airflow. In fact, it's elementary. External resistors, pulse width modulated signals, zener diodes, thermistor response and other tecniques can be used to change fan speed through a single, added control lead wire connected to ground.

Voltage Regulation

ThermaPro-V solves the problem of power supply voltage fluctuation forever. Internal Voltage Regulation circuitry automatically regulates the input voltage to the motor windings to compensate for any fluctuation
