Sensitron Unveils the SPHM/SEHM Series

Sensitron Semiconductor, a prominent U.S. manufacturer specializing in high-reliability power electronics, has recently introduced its cutting-edge SPHM/SEHM Series. This family of Solid State Power Controllers (SSPCs) is specially designed for 270VDC power distribution systems, providing engineers with enhanced capabilities for power management.

The SPHM/SEHM Series consolidates critical functionalities such as circuit protection, load switching, and real-time monitoring into a single intelligent module. The innovative design utilizes a microcontroller-based architecture that simplifies system integration by replacing traditional discrete circuit breakers and solid-state relays.

Key Features

One of the standout features of the SPHM/SEHM modules is their ability to offer 16 independently controlled high-side channels. Each channel is programmable, allowing current settings from 1A to 10A, leading to a total capacity of up to 160A. Notably, the channels can be paralleled, catering to high-current loads and enabling system designers the flexibility to optimize their power distribution setups.

Built-in Protection

Safety is a critical aspect of the SPHM/SEHM Series. The controllers are equipped with True I²t protection, which includes thermal memory and an instant-trip capability, ensuring the safety of both the loads and the wiring. Moreover, the soft turn-on and turn-off functionalities effectively limit inrush current and minimize electromagnetic interference (EMI), which are crucial factors in today’s electronically dense environments.

Comprehensive Monitoring

Visibility into system performance is another advantage of this series. Each module features integrated current, voltage, and temperature sensing, providing accurate readings within a 5% tolerance across the entire operational temperature range. Channel status and measurements can be communicated to the system controller through dual CAN or dual RS485 interfaces. This feature supports remote diagnostics, power budgeting, load shedding, and condition-based reconfiguration.

Additional Functionalities

The SPHM/SEHM Series is packed with additional functionalities such as:

• - Continuous Built-In Self-Test (BIT) during start-up and operation.
• - Galvanic isolation between the control interface and the power line, protecting sensitive components from interference.
• - Bootloader functionality for field-updatable runtime code.
• - Ample onboard code space for customizable applications developed by users.
• - Robust conduction cooling that allows operation in extreme temperatures, ranging from -45°C to +100°C.

Joseph Castaldo, Vice President of Sales and Marketing at Sensitron, remarked, “The introduction of our latest 270VDC Solid State Power Controller signifies a substantial advancement in thermal management, effectively lowering junction temperatures by 15% compared to conventional components.” This is achieved through the implementation of advanced wide-bandgap semiconductor materials, thereby enabling engineers to push the limits of power distribution in demanding sectors, particularly aerospace and defense applications.

Configurations and Applications

For integration, the SPHM Series is supplied as an open-frame card, whereas the SEHM Series comes with an IP67-rated enclosure, making it suitable for harsh environments. This versatility makes these controllers ideal for military ground vehicles, unmanned and manned aerial vehicles, marine vessels, energy exploration equipment, command centers, and off-highway vehicles.
