Details

Tibbit #25 can generate up to 1.5A of 5V power from an external input in the 8-60V range. Although this Tibbit is primarily intended for 24V and 48V applications, it is equally suited for 12V systems (albeit the current it is capable of providing with 12V input is lower).

The following table details the maximum ambient temperature at a given output current and input voltage:

Output current	@ Input V	Ambient Temp.
up to 1A	@ 12V	up to 70°C
up to 1.5A	@ 24V	up to 60°C
up to 1.0A	@ 24V	up to 80°C
up to 1.0A	@ 48V	up to 60°C
up to 1.0A	@ 60V	up to 50°C
up to 0.5A	@ 48V	up to 80°C
up to 0.5A	@ 60V	up to 70°C

Multiple power supply Tibbits can be used to increase available current or for power redundancy.

Tibbit #25 has a dedicated shutdown (–SDWN) line. Pull the line LOW to disable this module.

Combine Tibbit #25 with #18 (it has a power jack and two terminal blocks), #20 (nine terminal blocks), or #21 (four terminal blocks).

LEDs

There is one green and one red LED. The green LED is connected to the +5V output and lights up when voltage is present on this line. The red LED is connected to the –SDWN line and lights up when the line is LOW (i.e., when the power supply is shut down).
