Float-Boost Chargers

Power Services offers Float-Boost Chargers. It is designed to supply continuous power to the DC load and simultaneously charge the batteries connected. Input supply of 415 V AC 3-phase or 220 V AC single phase is converted to regulated DC. It has two independent systems. Normally the DC power is supplied to he load by the float charger. It also supplies trickle current to the battery to keep it healthy. If the charging current under Float mode exceeds a set level, the boost charger is switched On. It supplies quick charging current to the battery. On battery reaching the set value, the boost charger is switched Off. Application: float/ boost chargers are must in power substations, generating stations, telephone exchanges, etc., for control/ monitoring systems, tripping circuits and suppling DC power source.
