Brushless AC Axial Fan Options
Dual Voltage: Some Mechatronics AC axial fans are available in a 115/230v dual voltage package. These models can be wired for either 115vac or 230vac operation in a given application. Each fan includes 4 unique colored lead wires. Fans can be hooked up for 115v or 230v by following the wiring diagram included on each fan.

Environmental Protection: Mechatronics AC axial fans are available with environmental protection options ranging from light coating to full encapsulation. Available options vary by model.
- Conformal Coating - Fan motor windings are treated with a thin coating prior to installation into the fan frame. Conformal coating is designed for light moisture exposure such as condensation.
- Encapsulated Motor - Fan motor windings are sealed with potting material to prevent water and dust ingress. Encapsulation is designed for direct water exposure and has been tested to meet IP55 requirements.
- Encapsulation + Salt Fog Protection - Fan motor windings are sealed with potting material to prevent water and dust ingress. Supplemental coating is added over all exposed areas of fan motor to prevent corrosion from salt exposure.
Multiple Speed: Mechatronics AC axial fans and impellers are available with 2 speed options in the same unit. 2 speed models are supplied with 3 lead wires. Black and blue wires are used for low speed operation. Black and brown wires are used for high speed operation.
Tachometer & Alarm Output Systems
Some Mechatronics AC fan sizes are available with optional tachometer or locked rotor alarm output for fan performance monitoring.
These options require AC voltage to power the fan motor and separate DC voltage to power the signal circuit. The signal output wires do not have to be connected for the fan to operate.
AC fans with a signal output option will have 3 additional lead wires:
The AC fan signal output is open collector. The application must include a pull up resistor across a DC power source in order to provide voltage on the output.
Tachometer Signal (B1 Suffix):
The tachometer signal can be used to measure and monitor fan speed. The output is one pulse per revolution and is a square wave output
Locked Rotor Alarm Signal (B2 Suffix):
The locked rotor alarm signal is a high on pass, low on fail signal. Voltage output is present on the signal wire when the fan is rotating normally. The voltage drops to zero if the fan rotor is locked.
Not all options are available in all models. Please contact Mechatronics for available options for a particular model.
