Power Switching Electronics (PSE)

Power Switching Electronics (PSE)

Integrated Solution for Secondary Rideshare Payloads

The Power Switching Electronics (PSE) component is configurable for up to 6 channels of power switching and monitoring. The unit is compatible with traditional communication interfaces. The PSE Switches unregulated power to the spacecraft bus components or payloads via opto-isolated control. It has provision for red limit (hardware circuit breaker) and yellow limit (software configurable) and can be integrated with the telemetry module.

Stackable, extendable design—more channels, variable current limits
6U  form factor
Local microcontroller logic allows “setpoint” control of output current
Modular interface card can be selected for Spacewire or RS-422 communications
Two design configurations

  • Short duration
  • Long duration / high reliability
