DC0550 VARIABLE SPEED CONTROLLER BRUSHLESS THERMATIC® FAN & EWP WITH 1/4" NPT THERMAL SENSOR

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.

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

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.
