The 53501 Series Solid State Power Controllers are light -weight devices resistant to damage from shock and vibration, and
immune to contact-related problems (contamination, arcing) associated with mechanical equivalents.
Transformer coupling bet ween the input and output stages provides effective isolation up to 1000 V RMS. The Power FET
output eliminates bipolar offset and minimizes output voltage drop.
The preferred control input is CMOS enabling a fully functional Status Output. The input operates from a bias supply of 4.5 to
5.5VDC (See Figure 1).
Integral short-circuit protection, I
2
T trip and status output is provided. These units sense excessive current flow while under
2
load or while switching, and respond with an I T trip curve opening the output. An open-collector status is available to
indicate that the short circuit protection has been activated. The output will remain blocked indefinitely until the short is
removed and the unit reset. This feature prevents damage to the controller and also averts further system failures that may
be caused by the short circuit. Status line output remains on until the relay is turned off for resetting. Resetting the unit can
be accomplished by recycling the input control.
The devices are available in a variety of quality levels from COTS to class K including any custom screening requirements.
