24v, 1Amp, Battery Backed Switch Mode Power Supply

All Fase Controls class change time clocks require a 24vdc supply to power the time clock controller and class change circuits where installed.

The FASE/PSU/24/1 switch mode power supply is a highly efficient, battery backed 1amp power supply ideal for use with our range of class change time clocks and is suitable for powering dedicated class change sounder or motorised bell circuits where installed.

If using a power supply to power electronic class change sounders or motorised bells then circuit loads and volt drops should be calculated. See our Class Change Design Tool.

Use the drop down box above if you require batteries supplying with the power supply.
