SPDM16C11 DIAMONDBACK Series SENSITRON SEMICONDUCTOR Part Number: SPDM16C11, Rev 122908 DIAMONDBACK Series Programmable Multi-Channel Solid State Power Controllers The Diamondback Programmable MultiChannel Solid State Power Controller (SSPC) is a microcontroller-based, COTS Solid State Power Controller board designed for 28VDC applications. Each channel of the Diamondback has software-programmable current ratings and can operate grouped with other channels to support loads up to 150A. The board has integrated current, temperature and voltage sensing and no derating over temperature. Parameter measurements, system status information and control commands are issued over a serial communications interface. Features: • • • • • • • • • 16 electrically-protected channels Programmable ratings from 0.25A to 25A Parallel channel capability up to 150A Total current capability of up to 160A Max power dissipation less than 20W True I2t and thermal memory protection Normal and SensWide™ instant trip Trip-free reset circuit Current, temperature, voltage readings • • • • • • • • • Hi accuracy over temperature range Controlled turn-on/off to reduce EMC Trip disable and maintenance modes Power-up and continuous built-in-test Optically isolated input and outputs Isolated electrical control circuit 5VDC auxiliary power option Conduction cooled board -55oC to 85oC operating temperature Benefits: Sensitron’s SSPC technology and products combine the functionalities of electro-mechanical breakers, solid state relays, and system monitors, thereby providing the following benefits to our customers: • • • • • Electrical load protection and monitoring - current, voltage and temperature measurements Operational improvements by allowing for diagnostics, prognostics and condition-based maintenance Life cycle cost savings and reduced cost of ownership Increased radius of operation through power budgeting and load shedding Crew offloading and network-controlled intelligent load management Application Areas: Sensitron’s SSPC products are ideal for use in Power Management applications in the following markets: • • • • Military Ground Vehicles Unmanned Aerial Vehicles Marine Vessels Test & Industrial Equipment • • • • Communication and Command Centers Energy Exploration Equipment Off Highway and Heavy Duty Vehicles Medical Emergency Vehicles • Phone (631) 586 7600 • www.sensitron.com • E-Mail: [email protected] • Page 1 SENSITRON SEMICONDUCTOR DIAMONDBACK Series Product Brief v1.1.6 CURRENT PROTECTION Similarly to the traditional electromechanical circuit breakers, the DIAMONDBACK protects electrical circuits by closely controlling the I2t factor. CHANNEL PARALLELING Multiple individual channels can be paralleled in order handle large current loads. The new current rating is calculated as the sum of the individual channel ratings. To use channels in parallel, simply tie the channels’ load pins together, put the board in maintenance mode, and program the required parallel combination. HEALTH MONITORING DIAMONDBACK Solid State Power Controller provides current, voltage and temperature measurements. This information can be used to monitor electrical loads and perform tasks such as diagnostics, prognostics and condition-based maintenance. BLOCK DIAGRAM DIAMONDBACK’s architecture is comprised of high side switches controlled by a central microprocessor. The switching blocks are responsible for the control of individual channels. The processor performs all necessary measurements, data processing, and communicates to the user’s application through a CAN communications interface. Figure 1 – Block Diagram CAN COMMUNICATIONS All communications between the Diamondback and the controller is conducted via a J1939 compliant CAN communications interface. Diamondback only responds to the user’s commands, however, user’s software is not required to operate the Diamondback Series products. Communications interface commands are defined by Sensitron’s Interface Communications Document (ICD).
