12 Volt and 24 Volt 36 and 72 Watt DC UPS Battery Backup Power Supplies, DIN Rail


The PST-SP series of battery back up power supplies consist of a universal input (85 to 260 volts AC, 47 to 63 Hz, or 120 to 340VDC) 12 volt (or 24 volt) power supply with a built-in DC Battery Backup charger and switch. They can charge any 12 volt (or 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. They are designed for infrequent battery use. The charger current is small, so it charges the battery slowly and may not be applicable to systems having frequent, regular power outages

150 Watt 12V version

The battery voltage is not regulated, and the output during AC operation is the same as the battery charge voltage so the 12 volt system will vary from about 13.6 to 10 volts during operation. The 24 volt system will vary between 27.2 to 20 volts during battery operation. If battery back-up is not required there is pot for adjusting the power which is accessible from the outside. There is also a remote turn-on option to allow low voltage switching of the AC power, but not the battery power.

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 140 to 340 VDC.

AC DC Power Supply with Battery Backup

12V adjustable between 10.5 and 13.5 volts

24V adjustable between 22.5 and 25.5 volts

12V adjustable between 10.5 and 13.5 volts

24V adjustable between 22.5 and 25.5 volts

Voltage when used with battery backup function

User must adjust the output voltage to 12.9 to 13.8 volts to ensure battery charging

User must adjust the output voltage between 25.8 and 27.6 volts to ensure battery charging

User must adjust the output voltage to 12.9 to 13.8 volts to ensure battery charging

User must adjust the output voltage to between 25.8 and 27.6 volts to ensure battery charging

Voltage during battery operation

12.5 volts to 9.3volts

25.7 volts to 19.3 volts

The power supply will continue to supply power up to 140% of rated current and then will go into “hiccough” mode, turning on briefly to check if the current is too high, then turn off again. During the “off” phase of the hiccough battery power is present.
