Solid-state power controllers (SSPCs) provide advantages over relays and circuit breakers including being more accurate in measurements, offering faster short circuit and overload protection, and greater reliability as they are not subject to erosion or oxidation issues. SSPCs also save weight and volume, come in multiple mounting styles to work with AC or DC power, and can enhance system availability while lowering power dissipation and providing higher power volumes.

2. INTRODUCTION
An experienced physicist, Mark Thek is the president of Leach
International, a company acquired by Esterline Power Systems in Los
Angeles. At the firm, Mark Thek produces power distribution and
solid-state power controllers (SSPCs).

3. The solid-state power controllers are designed for a wide range of
weight and volume savings. They have multiple mounting styles to
be matched with both AC and DC power distributions. Solid-state
power controllers provide multiple benefits compared to the use of
relays or electromechanical circuit breakers. For example, SSPCs
can measure more accurately than the other two and provide high-
quality and fast short circuit protection and overload protection.
SSPCs are also more reliable as they cannot be subject to erosion
and oxidation, which can affect the functionality of relays and
breakers.

4. In this way, solid-state power controllers can enhance the
availability of a system and machinery. They can also lower power
dissipation and provide higher power volumes than the other two.
