2. KEY FEATURES AND FUNCTIONS

2.1 Multiple Inputs

PM200 master power unit may have multiple charging
sources at any one time. These sources include AC mains,
solar and starter battery (vehicle).
Charging priorities are listed within the table to the right.

2.2 Battery Charger Of Stationery/Service Battery

The charger automatically starts when the appropriate qualified power is connected, either from AC mains, alternator or solar.
With multiple charging stages (soft start – bulk – absorption – float – recycle), PM200 is designed to fully charge a battery quickly.
To guarantee the optimal charging for batteries of different states, the PM200 features a 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.
When the charger is at float Stage, if input a new source (AC Mains or Solar), the charger will return to the BULK stage.

Battery Temperature Sensor
The PMBS (Battery Temperature Sensor) supplied with PM200, 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 PMBS is not present, the PM200 will use 25°C as default.
Voltage Compensation Charging
With a voltage sensor PMBS the PM200 can, if required, 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 PM200 can be configured to charge lithium batteries. With lithium batteries, the max charging current will automatically be set at
30% of battery capacity (Imax=0.3C).
2.3 Vehicle Battery Charger
Along with a powerful charger for service battery, PM200 offers a float charge of up to 3A to keep the starter battery charged, whether
connected to the AC main or PV. When starter battery is less than 12.4V, the PM200 starts charging after 30 minutes delay and stops
charging when voltage reaches 12.8V.

2.4 Power Supply Mode

If no battery is attached to PM200 unit, it will work as a power supply automatically with a 12.8VDC output.
