Votronic 1266 LCD accucomputer 200 S Smart Shunt

• Votronic 1266 LCD Battery Computer 200 S with numerous functions.
• Monitoring of charging and discharging currents and more.

The Votronic LCD Battery Computer 200 S (MPN 1266) features 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 of the 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 of e.g. 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

Monitoring of discharge currents (load) by consumers, indicated by a "–" sign, monitoring 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 of 2nd battery (e.g. starter battery), 7 to 32 V (Volt), internal measurement resolution 0.1 V

Switching output freely programmable and testable (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-backlit, 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 using 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 extractable 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 vehicle's starter battery.

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. Switch-on and switch-off points are freely and independently adjustable in %, enabling 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, 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 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 completely connects the display to 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 devices are matched to the measuring shunts included in the delivery and cannot be operated with other measuring shunts or exchanged among each other!

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