Overview
The BF-6950 is a split-type refrigeration controller with an AC220V mainboard and a DC12V touchscreen, designed for −50°C to 100°C temperature control with 1–100A current detection and complete defrost, fan and alarm handling. The split layout lets the touchscreen and the power wiring be mounted separately, which suits cold storage and refrigeration panels where the operator interface and the mainboard sit in different positions.
Built for continuous refrigeration duty, the BF-6950 drives the compressor with start-up delay protection, runs periodic defrost, manages the evaporator fan and handles external alarms, while current detection guards the compressor against overload. It is a dependable choice for cold storage and industrial temperature control installations that need a clear touchscreen interface and a robust, separated control layout.
Key functions
Split-type refrigeration control
An AC220V mainboard with a separate DC12V touchscreen gives flexible mounting for cold storage and refrigeration panels.
Complete defrost & fan handling
Periodic defrost with dual time/temperature stop, drip-off and fan management keep the evaporator clear and temperature steady.
Current detection
Built-in 1–100A current detection protects the compressor in continuous refrigeration operation.
Alarm handling
External alarm input and high/low temperature alarms safeguard cold storage against control faults.
Where it's used
Cold storage & refrigeration
The BF-6950 holds the cold room at setpoint, runs defrost automatically and protects the compressor — solid temperature control for everyday refrigeration.
Distributed panel installations
The split touchscreen and mainboard mount separately, fitting installations where the display and power wiring are apart.
Industrial temperature control
Robust defrost, fan and alarm handling make it suitable for industrial refrigeration that runs continuously.
Installation & use
Mount the touchscreen in a 187×126 mm cut-out and place the AC220V mainboard near the refrigeration wiring, connecting the DC12V screen. Position the temperature sensor where it reflects product temperature and route signal wiring away from power cabling.
Fit the defrost sensor on the evaporator return pipe with waterproofing so defrost ends on time, size the compressor contactor with margin, and add an independent temperature alarm on critical cold storage.
Frequently asked questions
- How does the BF-6950 differ from the BF-6910?
- Both are split-type touchscreen controllers. The BF-6950 is configured for refrigeration with built-in current detection; the BF-6910/6911 is the touchscreen line where current detection is the 6911 variant.
- What temperature range does it control?
- −50°C to 100°C at 0.1°C resolution, with complete defrost, fan and alarm handling for refrigeration and cold storage.
- Does it include current detection?
- Yes. The BF-6950 has built-in 1–100A current detection to protect the compressor.
