Know before you buy
Yes, this controller is specifically optimized for Laing DDC pumps. It provides the necessary power and control logic to manage these pumps effectively within a custom cooling loop.
The Poweradjust 2 USB uses DC voltage regulation rather than PWM. This is ideal for components that perform better with a steady voltage supply, ensuring smooth and consistent operation.
The unit includes a configurable Start Boost function. This allows you to set a higher voltage for a brief period during startup, ensuring your pump or fan reliably overcomes initial resistance before settling into your desired speed.
Yes, the unit features inputs for external temperature sensors and flow meters. You can monitor these metrics directly through the USB interface using the Aqua Computer software.
The device utilizes a two-stage overload protection system. It actively monitors for temperature spikes and current limits, automatically adjusting output or shutting down if necessary to prevent hardware damage.
It is rated for a continuous load of up to 25W at 12V. It can handle short-term peak loads of up to 48W, which is useful for managing the high starting currents of certain pumps and fans.
