SR500L – SR750L – AC/DC Power Supplies – Battery Chargers 500W – 750W

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.
