The DRS-240 is a DIN rail buffer power supply with a maximum output of 240W. The power supply is available with output voltages of: 12V, 24V, 36V and 48VDC. The unit has two outputs: one for connecting a load and one for connecting a battery. The maximum load on both channels must not exceed the rated power of the power supply (240W). Thanks to the ability to adjust the charging current, the DRS-240 can work behind batteries with capacities from 5 to even 200AH.

The DRS-240 is equipped with four relay outputs indicating states: AC OK, DC OK, CHARGER FAIL, BATTERY LOW.

The unit has the option of programming the curve and changing the charging parameters using an external programmer SPB-001 (only on models with CANBus). Thanks to the MODBus protocol, continuous monitoring and diagnostics of the unit are possible.

The DRS-240 finds use in power backup systems (e.g. lighting), alarm panels, monitoring equipment and industrial automation in the broadest sense.
