Altech Corporation's CFTD fan monitoring modules protect industrial equipment through intelligent fan current monitoring and temperature control. The series includes three models: CFTD2 (two-fan), CFTD4 (four-fan standard), and CFTDPR4 (four-fan with AC power redundancy).
Each system offers current monitoring with configurable over and under-current thresholds and automatic calibration to establish baseline parameters for accurate fault detection. Models also include 3-wire RTD sensor inputs for temperature monitoring with programmable set points and 4–20mA analog output for integration with building management systems.
There are also three fault recovery methods: alarm-only, manual reset, or automatic retry with 30-second intervals.
The flagship CFTDPR4 offers AC power redundancy, automatically switching to backup fans when primary power fails and ensuring continuous cooling during power faults.
Technical specifications for the CFTD modules include:
- Power input: 100 to 240V AC single phase
- Current monitoring range: 0 to 750 mA per fan channel
- Temperature display range: 0 to 100°C (3-digit display)
- Temperature sensor: 3-wire RTD input
- Analog output: 4–20 mA proportional to ambient temperature
- Operating temperature: 32 to 122°F (0 to 50°C)
- Mounting: DIN rail compatible
- LED indicators provide real-time status updates for quick diagnostics
