Votronic 1269 LCD Battery Computer 400 S Smart Shunt

• Votronic LCD Battery Computer: 400 S with numerous functions.
• Control of charging and discharging currents and more.

The Votronic LCD Battery Computer 400 S (MPN 1269) has a significantly more accurate measuring shunt compared to its predecessor. The new Smart measuring shunt is included in the delivery. In addition to higher accuracy, the self-consumption has been further reduced. The functional scope, dimensions, etc. are identical to the predecessor model.

Microprocessor-controlled, the following values are measured, calculated and displayed

Battery voltage on-board battery 7 to 32 V, internal measurement resolution 0.1 V. Allows conclusions about battery behavior under different loads and serves for function control e.g. of the charger, solar system, alternator etc. Flashing warning display in case of overvoltage.

Battery current (charge/discharge) +/- 0 to max. +/- 1800 A, internal measurement resolution 0.1 A

Control of discharge currents (load) by consumers, indicated by a "–" sign, control of charging currents, indicated by a "Charge" sign.

• Battery capacity (Ah and %)

Remaining charge from 0 Ah / 0% (empty) to nominal capacity max. 2000 Ah / 100% (full)

Battery voltage 2nd battery (e.g. starter battery), 7 to 32 V (Volt), internal measurement resolution 0.1 V

Switching output freely programmable and keyable (PNP, positive potential 12V / 24V, max. 0.5A)

• Including remaining time display

How much remaining charge does my on-board battery actually have? Is the battery really full? Why is energy being drawn from the battery even though consumers are switched off? The VOTRONIC LCD Battery Computer S answers these questions to the percent (%) and ampere-hour (Ah) exactly. At the push of a button, it provides comprehensive information about the current state of charge of the battery, the flowing battery currents and the voltage level of the battery. Based on the extremely proven VOTRONIC LCD Battery Computer, the LCD Battery Computer S was developed. The versatile, easy-to-use display functions have been expanded with a white-lit, clear LCD display that is very easy to read even from a great distance and in poor lighting conditions.

The device is constantly in contact with "its battery" and thus registers and evaluates all battery actions. All charging and discharging currents are meticulously counted, battery size, self-discharge, battery load etc. are taken into account based on programmed characteristic curves. From the measured values and the battery size, the remaining capacity of the battery is then calculated. The result is the correct display of the state of charge (the remaining capacity, remaining charge) of the on-board battery as a numerical value in ampere-hours ("Ah") and in percent ("%") as well as a clear fill level bar, like a fuel gauge. The LCD Battery Computer S is suitable for all battery types (acid, gel, AGM, lithium adjustable) with 12V and 24V battery voltage.

Of course, the current battery voltage ("V") and the current battery current ("A") are also available in the display. Discharge currents (consumers) are indicated by a minus sign. Charging currents are also indicated by a clearly readable "Charge" sign. Independently of this, there is another display option for the voltage of a second battery, e.g. for monitoring the starter battery of the vehicle.

The LCD Battery Computer S has a freely programmable switching output for control, monitoring and warning purposes, e.g. to automatically switch consumers depending on the state of charge of the on-board battery (0-100%) or to output a warning. On and off switching points are freely and independently adjustable in %, which enables any switching functions. In addition, they can be manually overridden at any time by pressing a button.

• Application example: Automatic protection of the battery against harmful deep discharge, the consumers are switched off exactly according to the state of charge, e.g. at less than 25% state of charge. At the push of a button, an emergency-on function is possible to continue supplying the consumers. The device can thus also be used as a remote-controlled battery main switch (on/off) with deep discharge protection.

A ready-to-connect cable connects the display completely with a robust precision measuring resistor (shunt), which is connected directly to the negative pole of the on-board battery and at which the voltages and currents of the battery are recorded. The switching output for connecting signal transmitters or powerful switching relays is also located here.

The selection of the appropriate Smart Shunt (100 S, 200 S or 400 S) depends exclusively on the maximum continuous load by the consumers (A) and not on the total battery capacity (Ah).

The devices are matched to the measuring shunts included in the delivery and cannot be operated with other measuring shunts or exchanged with each other!

Matching the VOTRONIC module system, the device fits optically and mechanically (uniform height 85 mm) to the other display modules and the low installation depth of only 22 mm allows mounting almost anywhere.
