OPERATING MANUAL
PHF-HD3-1201P-24/25
TECHNICAL FEATURES
Advanced technology high frequency system.
Charging process fully controlled by microprocessor.
Universal input voltage: 100-240 Vac
Charging process initializes in "soft start" mode.
Available on request: Automatic reset on insertion of a new battery and automatic charge cycle start.
Protection against polarity inversions, short-circuits, over-voltages or anomalies by means of an output relay.
Battery to battery charger connection without sparks on the output terminals with obvious advantages for
active safety, thanks to the recognition of the battery voltage downstream of the normally open output relay.
Signaling of possible anomalies by LED indicators.
Insensitive charge parameters in case of ±10% network voltage oscillations.
Efciency > 85%.
Output ripple at maximum charge lower than 100mV.
Start of the charge cycle even with 2V batteries.
OPERATING PRINCIPLE
To use the charger, plug the the AC input cable in to an outlet and then connect the battery/battery pack to DC
output cable. The charger will start by checking the battery voltage for a few seconds and then begin the charging
process and the red LED will turn on. If a battery is not connected or if there's a problem with the DC signal, the
yellow LED will ash. When the charging process starts, the output relay closes and the current of the rst phase
rises slowly until the nominal programmed value is reached. If the user disconnects the battery during the
charge, the charger will reset itself after a few seconds and restart the charge process if the battery is
reconnected. There are three (3) LED indicators that provide charging status and error codes. Refer to the table
below for descriptions of the visual signals.
