Important characteristics and features

Priority principle

The priority principle gives you the option of specifying that consumers are switched off according to priority (urgency) when the battery charge drops. Each consumer must be preceded by its own deep discharge protection, for which the desired cut-off voltage has been selected.

Dynamic deep discharge protection

The dynamic deep discharge protection determines the remaining battery capacity from the battery voltage and load current. It thus offers more intelligent protection than conventional controllers with a constant load switch-off threshold.

Example: The battery voltage at which loads with high current consumption are switched off is lower than that of loads with low current consumption. However, the remaining capacity in the battery after disconnection is the same in both cases.

As soon as the battery is recharged and the load reset threshold (reset voltage) has been exceeded, the consumers are automatically switched on again.

Constant deep discharge protection

When using batteries with high internal resistance (small battery capacity or already sulphating batteries), dynamic deep discharge cut-off can lead to premature load disconnection.

Switching to constant end-of-discharge voltage 11.1 V (for 12 V systems) or 22.2 V (for 24 V systems) may be useful to be able to draw more current from the battery.

Clear LED status display

The charge status of the battery can be read at a glance with the help of 3 LEDs. Furthermore, the LEDs indicate whether deep discharge is imminent or whether the load output has already been switched off.

Application example – Prioritised switch-off

Prioritised disconnection of various devices in the holiday home

The disconnection of the consumers is prioritised by assigning a specific disconnection voltage to the respective deep discharge protection.

Less important loads (e.g. televisions) are connected to the deep discharge protection with the highest cut-off voltage (12 V). They are the first to switch off.

If the battery voltage drops even further, the second deep discharge protection (switch-off voltage 11.7 V) deactivates the consumers with higher prioritisation (e.g. lighting).

The consumers with the highest priority (e.g. emergency lighting, radio system) are connected to the third deep discharge protection (switch-off voltage 11.3 V) and switch off last.

3 year manufacturer warranty

IVT products are manufactured to a high quality and following strict quality guidelines. We are certain about the longevity so that we add another year to the statutory manufacturer warranty free of charge. Rechargeable batteries and batteries are excluded from this warranty.
