The new PolarStar Mini FCU is a more compact and less expensive option for single-solenoid HPA systems.
New voltage regulators allow for extremely low power consumption in sleep mode. Drawing under 28uA while idle, the Mini FCU is over 300 times more efficient than the original Standard FCU and can operate in sleep mode for close to one year on a small 250mAh pack.
Elimination of the solenoid MOSFET, joystick and LCD, along with careful selection of the remaining components, allowed the size of the Mini FCU to be reduced significantly compared to other FCUs....
