HS-PWS and HS-D brake power supplies
The HS-PWS and HS-D brake power supplies provide significantly faster current stabilization and smoother output compared to the PWS3.2 and earlier models.
This is possible thanks to the control carried out 1000 times per second, based on IGBT technology.
The HS-PWS also features a high-speed 32-bit microcontroller (MCU) and CANBUS communication for full control and feedback.

Important information
The advantages of the HS-PWS/HS-D models are usually most noticeable in engine dyno and HUB dynos
(generally – dynos with low inertia).
For roller dyno, PWS3.3 and lower models already provide a sufficiently fast response, so the use of HS-PWS does not always bring additional benefits.
⚠️ Technical Note:
The higher switching frequency in the HS-PWS results in higher electromagnetic interference emissions, which requires:
-
use shorter brake hoses,
-
use shielded cables – if possible.
