CBC Design: High Voltage Monitors.



The High Volts Monitor measures your battery or charger output and trips an internal relay (used to switch your warning leds or buzzers) if the battery voltage rises above a safe (adjustable) level. Drawing less than 2 Watts, the unit is ideally suited to protecting your batteries from being overcharged which damages the cells, in most cases permanently.

If your battery is crucial to the reliability of your boat, golf cart, car, mobile home etc, the high voltage monitor makes sure your batteries are below the upper recharge limit and in doing so can extend the life of your cells by months or even years.


The unit is fitted with on-board through label healthy & failure leds and includes a double pole volt free relay rated at 3A @ 230VAC or 30VDC. Connections and installation requires an 11 pin octal base (Included!).

High voltage monitors are available in 6, 12, 24, 30, 48, 60 & 110VDC versions, there are few if any real-world situations in which this product cannot be applied. If you have an application where you need the dc supply to sit within defined limits, this is the product for you. Click the image on the right to download a data sheet.

Backed up by a twelve month guarantee and designed for a twenty year life, you can at last relax, safe in the knowledge that your cells will never be overcharged without warning again.
