24V Power Supply Unit

 

​

The 24VPSU is an efficient compact 100W ac to dc power supply unit, which is designed to fit in to the frame of a backpack. 

 

It is operated from a nominal supply voltage of 110Vac or 220Vac at a frequency of 47Hz to 63Hz and supplies 24Vdc. 

 

The unit has completely independent built-in test circuitry which monitors the supply power and output voltage.  A LED above the input and output connectors displays the status while the “Status” button is pressed. 

 

The output current is monitored internally and should an overload be detected the output is shutdown for 10µs.  The unit will continue to restart itself until the fault is corrected. 

 

The unit also has built in short circuit protection which is self recovering when the short circuit is removed.  An “On/Off” push button on the front panel allows the user to enable or disable the output.
