DATA ACQUISITION MODULE (DAM)
One per each battery (cell) to be monitored.
Technical data: - Available models: L - for 2V cells, H - for 6V and 12V batteries - Measures the battery temperature (-20/+80°C, ±2°C) - Measures the battery voltage (H type: 5 -18V, L type: 1.5 - 5.5V) - Measures the battery internal resistance (Ri=1-300 mΩ, ±10% or ±1mΩ), with Kelvin wiring - Protected against reverse polarity, internal short circuit and over voltage - Power consumption (typical): L type -> 80mA @ 2V (Sleep Mode: 9mA)
H type -> 30mA @ 12V (Sleep Mode: 4mA)
- Multifunction LED
