SR100L & SR250L have been replaced by the following models

SR100L – SR250L – AC/DC Power Supplies – Battery Chargers

The SRL models are designed for use as a precision AC to DC power supply, or a float charger for lead-acid batteries. Note that for float charging the output voltage must be set to approximately 15% above the nominal battery voltage. The SRL series can have an optional Ethernet, RS485 or RS232 communications port fitted.
