Power Systems Management (PSM), a new company founded to design and develop practical and useful control strategies for electrically driven devices, introduces the all new VC1240 variable speed, pulse width modulation cooling fan controller.

The stand alone VC1240 PWM fan controller has the following features:
* Stand alone - Can work with EFI or carburetted applications.
* Compact design - At 2.1" x 2.1" x 11/16" means it can be mounted to the inside of many metal radiator fan shrouds.
* Easy installation - Most applications will have a total of six wires: Power in, Power out, temperature sensor, and A/C override.
* High Current Capability - 40A continuous, enough to comfortably support the largest dual brushed fan applications while allowing a smooth ramp-in/soft starting feature.
* A/C override forces controller on to 50% power when connected to the compressor clutch or Bat+ trinary switch.
* Safety - The controller will tolerate a short circuit to ground or a short circuit to 12V, current overload, and over temperature conditions, and will do so indefinitelywithout damage.
* Under and Over Voltage Shutdown.
* Short Pulse Timing - Will work with all brushed type fans including Ford Contour and Taurus applications without causing unnecessary motor wear.
* Long Life - Designed with the electronic circuitry separated from the high power components means a MTBF that should outlast the application.
* Hermetically sealed
* UL-94 compliant materials throughout.
* A real data sheet: https://psm-protouringcom1.netdna-ssl.com/wp-content/uploads/2019/11/VC1245-VC1265-Datasheet.pdf
In development since March 2019 using a 35A Lincoln Mark VIII fan as the benchmark, this controller can drive even the largest twin brushed fans with little trouble. For twin fan applications both fans will run together, hence lowering the at-idle fan noise even more. Here's the prototype mounted to the plastic shroud using a metal plate to provide additional heat sink capability. Pardon the many extra screws, dials, and switches as this allows removal and testing a variety of functions without having to remove the fan shroud. In other words and in full disclosure, this is what a test mule looks like when mounted in the most convenient location.

The VC1240 is available from Northern Radiator under P/N Z18350 https://www.northernradiator.com/Product/Z18350?criteria=Z18350 This kit also includes a mounting bracket to allow flexibility (not in-shroud) in the mounting location.
Please feel free to ask any questions and I'll be happy to help.
