PowerGuard PRO – E-Marked & CE Marked for road-going vehicle use.
Low cost, basic flat battery protection device. PowerGuard Lite – CE Marked but not e-mark approved for auxiliary battery banks on vehicles and engine start batteries in non-road going applications. Auxiliary Battery Protection: ambulances, service vehicles and delivery vehicles fitted with tail-lifts. Proven applications include: Engine Battery Protection on front line ambulances, police cars, fire vehicles, hire boats, agricultural machinery and plant. If batteries are not put on charge (by starting the engine or switching on a battery charger for example), the unit will automatically isolate the batteries. PowerGuard employs advanced battery monitoring techniques to determine when battery state of charge meets a number of parameters (Digital Signal Processed voltage and time).
By automatically switching batteries off before they become flat, PowerGuard ensures that enough power is retained within a battery to guarantee engine starting and prevents excessive discharge of expensive auxiliary battery banks. PowerGuard is essential for anyone who’s life or livelihood depends on batteries. Merlin PowerGuard™ – Flat Battery Protection
