Power Supply for Heated Variants

DC Power Supply Voltage: 10 to 30.0vDC.
AC Power Supply Voltage: 24V RMS AC ±10 % @50/60Hz.
12VDC Power Supply: Allow for 2.2 Amps @ 12V DC (nominal supply), 26W max.
24VDC Power Supply: Allow for 4.2 Amps @24v AC or DC (nominal supply) 100W max.
Standby Heater Current: Approximately 40mA.

For optimal performance, especially during initial start-up, a dedicated 24vDC heater supply capable of delivering a minimum of 6 Amps is recommended for the WindSonic M’s heating system for initial heating start-up surges. While the heater supply is electrically isolated from the sensor’s power, it is acceptable to use a common 24vDC source for both, if necessary. It is crucial to ensure that neither the sensor nor the heater supply connections are ever connected to the WindSonic M’s metal casing.

To maintain efficient heating, the length of the heater cable should be kept as short as possible to minimise voltage drops and ensure the anemometer receives the maximum available voltage. If longer cable runs are unavoidable, consider connecting spare wires in parallel to the designated heater pins. This effectively increases the wire gauge, reducing resistance and subsequent voltage drops across the cable.

The heating system in the heated WindSonic M operates autonomously, activated by internal temperature sensors when conditions likely to cause icing are detected. There is no external command to enable or disable the heating; it is continuously active and cycles on and off based on the sensed temperature. To completely disable the heating, the heater power supply must be physically disconnected. As a confirmation of functionality, a one-minute burst of heating will automatically occur upon powering up a heated WindSonic M unit, provided the heater supply is connected. Furthermore, the WindSonic M incorporates reverse polarity protection to prevent damage from incorrect power connections.
