- Wide operating voltage range: 8-60 V DC. This refers to the control panel working within this range. The controller and the fan operate together, and the fan must meet its performance requirements to avoid damage. - Flexible low fan speed and temperature control: adjustable via button with a wide, programmable range. Settings can be saved for repeated use. - Switch stop alarm option: can enable an alarm function using an external AC buzzer; default is off. - Dual independent temperature control: two channels with alternating display of each channel's temperature. Temperature range from -9.9°C to 70.1°C with error less than 1°C. Use scenarios: - Industrial electronics enclosures requiring reliable two-zone temperature management and programmable fan control. - Data center or server rack cabinets that need precise temperature monitoring, adjustable fan speeds, and audible alarm capability. - Vehicle, solar, or other 8-60V DC powered equipment where compact temperature control and dual-channel monitoring are beneficial.
