Temperature sensor MTIAQ

Lead batteries have in case of stand-by operation a temperature coefficient of approx.- 3mV per °C

temperature rise and cell. The final charging voltage is determined in the way that a recharge of the batteries in a temperature range of 15 – 45°C is gu aranteed. For applications, which are subject to strong fluctuant or very deep temperatures, the final charging voltage should be adapted respectively to avoid an over-charge of the batteries (danger of gas!). As well in case of very deep environmental temperatures (Te < 15°C) the voltage tracking should ensure a sufficient battery charge. By connecting the temperature sensor at the terminal ‘temp’ connection 1 and 2 the voltage tracking is activated automatically.

According to the environmental temperature fluctuation the final charging voltage and therefore also the output voltage varies from 27,85 - 26,3 V DC. Battery temperatures above 45°C are indicated with the erase of the LED ’Batt OK’.
