Power Factor Correction (PFC)

Power Factor Correction (PFC) is included at the input to the chargers to reduce ac line current distortion.

Low Battery Disconnect Protection

The chargers have a low battery disconnect circuit to prevent damage to the battery by low discharge during a long AC failure.

A Low Battery Alarm (Form C contact) provides a warning before the disconnect circuit disengages the output.

Charger Fail Alarm

A Charger Fail Alarm is also provided (Form C) which indicates either failure of the charger circuit or loss of AC input power.

Temperature Compensation

The chargers also have a battery temperature compensation circuit with an external sensor, which is provided.

This circuit ensures that the float voltage is automatically adjusted according to the battery temperature.

The BTC sensor is a non-polarized type, which eliminates the possibility of incorrect connection.
