so-calledSSPCIt is a highly integrated intelligent power distribution device that can significantly reduce weight and volume. SSPC stands for Solid State Power Control, which refers to a solid-state power distribution system.Wei KeweiThe developed SSPC can realize relay and contactor power switch devices, with multiple installation methods, multiple rated current values, and voltage switching capabilities. It is used for different levels of AC or DC distribution.

SSPC has functions including AC and DC current sensing devices for all types of protection. The contactor and current sensing device components (such as overcurrent, undervoltage, overvoltage, reverse polarity, etc.) are designed as online replaceable units (LRUs) for easy replacement and installation. SSPC usually adopts a modular design to meet the needs of customers for reconfiguration and future upgrades. At present, this product design is often used to optimize the distributed or integrated architecture of aircraft characteristics.

Weikewei's SSPC module has reliable fault free switching and true short-circuit protection. If the module detects a short circuit in the load current and initiates a shutdown within microseconds. It has two status signals, from the load current value and equipment door, which are alerted by LED lights and can be fed back to the onboard computer or upper computer through the bus.

The device used is a power field-effect transistor, which adopts thick film technology and has the advantages of low power consumption, high off state impedance, low on resistance, and low on voltage drop. Our 28 VDC SSPC system does not require any load type derating for this module. Due to these characteristics, coupled with its high reliability, it has become an ideal choice for aircraft power system applications, and more and more user units are also praising Weikewei's products.
