The FAN-PWM-V3 now incorporates "over current" protection, "smart soft start" (reduced inrush while still protecting from stalled/stuck fans), onboard diagnostics with error code reporting and "status OK" light (easier to identify wiring issues and confirm unit is operating), a 16-bit micro controller (increased accuracy and functionality) and three selectable default settings (SPAL USA Fan-PWM-TS sensor required).
Furthermore, the controller is now compatible with both 12- and 24-volt systems with corresponding 12- or 24-volt fans (only 12-volt was previously available). It also accommodates a larger fan speed range (lower "Low" speed) and allows for smoother transitions to higher speeds (fan ramps up/down without turning on/off). It also comes with a premium-grade harness (GXL wire; full automotive OEM spec wiring).
"User feedback to our programmable fan controller has been overwhelming positive since we introduced the unit two years ago," said Brent Clark, chief operating officer, SPAL USA. "We listened to our customers' suggestions for making it even better and incorporated some of the best ideas into the new model."
