Smart Power Control with Pololu Isolated Solid State Relay/Switch, SPST, 30V, 11A
The Pololu Isolated Solid State Relay/Switch, SPST, 30V, 11A gives you electronic power control in a smaller and cleaner package than a bulky mechanical switch.
It is useful for battery-powered devices, robots, portable test gear, and projects that need soft on/off behavior or reverse-voltage protection.
Why you'll love it
- Rated for DC switching: up to 30V load voltage and 11A load current (absolute maximum)
- Low losses: typical combined MOSFET resistance around 10 mΩ when enabled
- Fast enough for switching tasks: turn-on up to 1.5 ms , turn-off up to 1 ms
- Small form factor: about 0.8″ × 0.32″ × 0.13″ , ~ 0.4 g
- Not for high-speed PWM: switching times are around 1 ms, so it’s not suited for signaling much beyond a few hundred transitions per second
- Control current: when enabled, the control circuit can draw up to 10 mA from VIN
What you can build
Useful in battery-powered robots, portable gadgets, control boxes, and builds that need neat electronic latching power control.
