Battery Temperature Compensation
When the optional battery temperature sensor TMS1 01 is connected the output voltage will
be adjusted by the amount shown in the table below to maintain the optimal battery
changing voltage.

(Reference Temperature = 20 °C)
SME240-1 2-20 -1 8 mV/C
Thermal Protection
A thermally controlled fan is used to maintain temperatures a non latching thermal shut
down is used to protect against overheating due to:
• Use in excessive ambient temperature
• Output overload
• Fan failure/blockage
• Other fault conditions
Battery Charging Operational requirements
Trickle Charge
When mains is present but the battery voltage is below the LVD Connect voltage, the
battery is trickle charged circuit that limits the charging current to a trickle charge current
of 1 .0A ± 20%.
Vfloat
During Vfloat mode the battery is charged at 1 0 A until the float voltage is reached.
Vequalise
Periodic equalise at 1 4.25 V is provided for 1 5 minutes every 24 Hours.
Battery Charge modes
To maintain the battery in a good state of health a charging algorithm is to be used to
ensure that the correct voltages are applied to the battery terminals at the appropriate
times throughout it’s usage cycle.
The voltages for each Mode at 20°C is:
Float Voltage Equalise Voltage
1 3.65 ± 2% 1 4.05 ± 2%
