The Pro Latch R is not a conventional relay. A conventional 80A / 12V relay would consume 450mA 'staying on'. This is fine when using a 70A alternator. However, when using a 60W solar cell on a typical cloudy day the output is around 400mA, the conventional relay therefore renders the solar cell useless.
The Pro Latch R is designed to 'lock into position' and will not consume power by 'staying on.' The only current drawn is to run the internal software which amounts to about 0.5mA (900x more efficient). This makes the ideal for use with solar cells or wind power, where every little counts
The Pro Latch R can be set to trigger 'on' and 'off' at certain voltages according to the user's need. 'On' voltages can be set from 10.7V - 14.8V and the 'off' voltages from 10.4V - 14.5V. There are also factory preset voltage trigger points which are suitable for 95% of applications.
