24 Volt 150 Watt DIN Rail Backup Power Supplies

24 volt 150 watt power supply with battery backup

The PST-SP24-150 series of battery back up power supplies consist of a universal input (90 to 265 volts AC, 47 to 63 Hz, or 130 to 375VDC) 24 volt power supply with a DC Battery Backup feature and switch. It can charge any 24 volt SLA, gel cell, VRLA, or AGM lead acid battery and instantly switch over to battery power upon power failure with zero crossover time. These power supplies can be used with or without the battery as convenient DIN rail mount power supplies. The charge rate depends on the exact voltage that the power supply is set for, but can be up to 3A minus the load current.

48V 150w Din rail mount battery backup power supply

150 Watt 48V version

The battery voltage is not regulated, and the output during AC operation is the same as the battery charge voltage so the 24 volt system will vary from about 27 to 20 volts during battery operation. If battery back-up is not required there is pot for adjusting the voltage which is accessible from the front panel.

These units can also be used as high voltage input DC/DC converters with battery backup. The input voltage can be DC instead of AC if the supply voltage is between 130 to 375 VDC.
