Variable Speed Controller Brushless Thermatic Fan & EWP +1/4"" NPT Sensor

VARIABLE SPEED CONTROLLER BRUSHLESS THERMATIC® FAN & EWP WITH 1/4" NPT THERMAL SENSOR Part #0550

*Note: Only for Brushless Motors, for Brushed Motors, see Part #0555

High-performance Controller designed to optimise thermal management in automotive, industrial, marine and EV applications. It provides intelligent, precise control of either Brushless dual Thermatic Electric Fans or Electric Water Pumps (EWP), ensuring maximum, efficiency, system protection and reliable operation in the most demanding environments.

Key Features

• Flexible operating modes: Four distinct control strategies to suit differing cooling system applications. 12 & 24 Volt Applicable.
• Independent dual outputs: Two fully isolated PWM signal channels allow for separate control of any combination of Brushless fan/s and/or Brushless EWP. Multiple Brushless fans or pumps can be wired to a single channel, provided the combined PWM signal current does not exceed .5A. Unique setpoints, and operating modes can be applied to each output independently.
• Shutdown control: After ignition-off, the Controller will keep fans running for user-defined time or until defined shutdown time is reached to prevent heat-soak.
• Manual overrides: Dedicated ON/OFF control per channel bypasses automatic control if required. Configurable polarity accommodates different wiring and switch arrangements.
• Safety & failsafe options: In the event of Sensor fault, outputs default to full speed to protect the system.
• Advanced Configuration options: Temperature difference, defined starting speed, shutdown time & temperature, temperature offset, factory reset, and adjustable PWM frequency.
• Rugged, reliable design: IP67 waterproof rating ensures durability in harsh conditions.

Kit Overview & Sensors

This kit includes two sensors, providing flexible installation options for coolant temperature monitoring.

• Sensor 1: Temperature Probe Detects ambient core temperature (in fins) or direct coolant fitment via Adaptor Kit (#0409 or #0408).
• Sensor 2: ¼ NPT Thermal Sensor Direct fluid installation (thermostat housing, engine block, or radiator tank). Adapters available for hoses.
• Optional: M12 x 1.5 Sensor Upgrade (#0462) allows you to use existing spare sensor ports in the cooling system.
