BDFC-01C Fan Control Board

WOODWARD 8440-2050 Generator Set Controller

Product Details Introduction

The BDFC-01C fan control board is an industrial grade fan control module commonly used in power electronic systems, frequency converters, servo drives, or industrial control cabinets to intelligently control and protect cooling fans. This control board is manufactured by multiple industrial automation companies and belongs to the general/customized electronic auxiliary module category.

1、 Product Overview

The BDFC-01C control board is mainly used to automatically detect the temperature or load situation of control equipment, thereby starting and stopping the cooling fan, extending the fan life, reducing energy consumption, and preventing system failure caused by excessive temperature rise in the control cabinet. Its control method may be based on relays, PWM, or voltage output, adapted to multiple fan power supply methods (DC or AC).

2、 Main functions

Temperature control start stop: automatically control the fan operation based on feedback from thermistor or thermistor device (NTC/PTC);

Multi channel output: can control the start and stop status of multiple sets of fans, supporting parallel fan loads;

Soft start and delay protection: reduces the impact of fan starting current, supports delayed start/stop;

Fault detection: such as fan stall, stalling, abnormal voltage alarm;

Communication support (some models): Supports TTL, 485, or analog signal reporting;

Multiple control modes: optional timed control, temperature triggered control, manual forced start.

3、 Technical specifications (typical)

Input power supply: 12VDC/24VDC (customizable)

Control output: relay contacts, PWM or MOS tube drive

Number of control channels: 2-4 channels (depending on the model)

Supported fan types: DC brushless fan (commonly 12V, 24V)

Temperature sensor: NTC thermistor interface (usually 10K Ω)

Working temperature: -20 ° C~+70 ° C

PCB size: customizable (commonly 80mm x 50mm)

Installation method: screw hole fixation/DIN rail

4、 Typical application areas

Cooling system for frequency converter and power module

Motor driver (servo, stepper) auxiliary cooling

Industrial control cabinet internal thermal management system

Communication base station or UPS internal cooling system

Industrial heating/welding equipment
