COBRA Series Programmable Multi-Channel
Solid State Power Controllers
The Cobra Series of Programmable Multi-Channel Solid
State Power Controllers (SSPC) are multi-channel,
microcontroller based, Solid State Power Controller boards
designed to for 28VDC applications. Each channel of the
Cobra series is software programmable for rated current
up to 25A and can operate grouped with other channels to
support large loads up to 150A of current. The Cobra is
intended to be used where multiple Solid State Power
Controller channels need to be co-located on the same
card or in a power distribution box. These boards have
integrated current sensing, temperature and voltage
sensing with no derating over the full operating
temperature range and communicate with the system
controller over an RS-232, RS-422, and RS-485 or CAN
serial bus.
Features:
• Up to 6 channels can be grouped together
• Programmable from 1 Amp to 25 Amps
• Parallel channel capability up to 150 amps
• Trip disable and maintenance modes
• Power-up and continuous built-in test
• Non-volatile storage of parameters
• True I²t and thermal memory protection
• Internally generated isolated supply
• High control circuit isolation
• Soft turn-on to reduce EMC issues
• Trip-free reset circuit
• Optically isolated input and outputs
• -55^oC to 100^oC operating temp range
• No heat sinking required
Benefits:
