DC0550 - Variable Speed Controller Brushless Thermatic® Fan & EWP +1/4"" NPT Sensor

*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.
