Description


SHANGFANG SF-574 Temperature Controller 250VAC with Precision Temperature Regulation

SHANGFANG SF-574 Temperature Controller delivers precise temperature control with a user-friendly design and robust performance.

SHANGFANG SF-574 Temperature Controller is designed for precise temperature regulation in various industrial and laboratory applications. It features a digital display for easy monitoring, a wide temperature range of -20°C to 150°C, and a quick response time of 0.5 seconds. The controller is compatible with 250VAC power supply and uses advanced control algorithms to ensure accurate temperature control. SHANGFANG SF-574 Temperature Controller is built with durable materials and robust construction to handle harsh working environments.

SHANGFANG SF-574 Precision Digital Temperature Controller

The SHANGFANG SF-574 is a professional-grade digital thermostat designed for high-accuracy thermal regulation in industrial and commercial cooling systems. Rated for 250V AC, it features multi-relay outputs to manage compressors, defrost cycles, and fan operations simultaneously. With its intuitive interface and robust sensor feedback, the SF-574 is an essential component for cold storage, refrigerated showcases, and laboratory incubators requiring strict Precision Temperature Regulation.

Technical Specifications

Parameter Detailed Specification
Power Supply 220V - 250V AC, 50/60Hz
Temp. Range -45°C to +99°C (-49°F to +210°F)
Accuracy ±1°C (±2°F)
Relay Contact Compressor: 10A/250VAC | Defrost: 10A/250VAC
Sensor Type NTC (Negative Temperature Coefficient)

Industrial Application & Reliability

The SF-574 is engineered for energy-efficient refrigeration control. Its dual-sensor capability allows for independent monitoring of ambient temperature and evaporator coil temperature, optimizing defrosting termination to save electricity. The anti-interference design makes it suitable for integration into supermarket blast freezers, medical storage units, and climate-controlled grow rooms.

Troubleshooting FAQ

Q1: The display shows "E1" or "EE" and the alarm sounds.
A: This indicates a Sensor Fault. Check if the NTC probe is securely connected to terminals. If the probe is damaged, replace it with an identical 10K NTC thermistor to restore precision tracking.

Q2: The compressor frequently starts and stops within seconds (Short-cycling).
A: Verify the Hysteresis (Differential) setting. A value below 2°C can cause excessive switching. Increase the differential or set a higher "Compressor Start Delay" (usually parameter F2 or similar) to protect the motor.

Q3: Defrost is running too long and heating up the cabinet.
A: Adjust the Defrost Termination Temperature. The SF-574 should stop the heating element once the evaporator reaches a safe limit (typically +5°C to +8°C), rather than relying purely on a timer.
