Battery Temperature Sensor
The BTS P/n: PM30 (Battery Temperature Sensor) supplied with PM435, measures the temperature of the
battery and automatically adjusts, in real time, to charge the battery properly at compensation rate of –
4mv±10%/°C/cell. In case BTS is not present, the PM435 will use 25°C as default.
Voltage Compensation Charging
With a voltage sensor the PM435 can, automatically adjust its output to compensate the voltage drop caused
by a cable. This assures the right voltage is being delivered for optimal charging.
Adjustable Charging Capacity
Users can adjust the charging current by specifying the battery capacity. The charging current is set at threshold
rate of 10% the of the battery capacity (I = 0.1C) by default.
Lithium Battery Charging
The PM435 can be congured to charge Lithium Iron Phosphate batteries. With the Lithium battery, the max
charging current will automatically be set at 30% of battery capacity (Imax=0.3C).

The PM435 accepts inputs from AC mains, Solar and Starter Battery (Alternator). However,
only one source will provide power at one time, see table below for details:-
2.2 Battery Charger Of Stationery/Service Battery
The charger automatically starts when the appropriate qualied power is connected, either from grid, generator or solar.
With multiple charging stages (soft start-bulk absorption oat-recycle), PM435 is designed to fully charge the battery quickly. To guarantee
the optimal charging for batteries of different states, the PM435 features Microprocessor-controlled charging algorithm. The Float and
Recycle charging programs guarantees that the battery condition does not change despite being connected for a longer period.
SOFT START
Increases battery life by gently starting to charge the battery
5% of bulk
BULK
Reduces charging time by delivering maximum charge to set
voltage life by gently starting to charge the battery 25% of bulk
ABSORPTION
Ensures a full charge to the battery without overcharging
FLOAT
Float charge maintains the battery at 100% charge
