The PELC-PT435.48.230 is a DC voltage monitor designed to supervise 48VDC battery banks. It is powered from a 230VAC mains supply and offers two installer-selectable operating modes: as a battery charge controller, or as a deep-discharge protection monitor.

In both modes, two voltage limits — an upper and a lower threshold — define when the output relay arms or releases. In Mode A, the relay arms when the battery voltage falls below the lower limit (battery under charge) and releases when it rises above the upper limit (battery fully charged). In Mode B, the relay arms when the voltage rises above the upper limit (battery charged) and releases when it falls below the lower limit (battery discharged).

Note: An 8-pin lamp-type connector base (code 525086) is required and sold separately.
