Dynamometer Controllers

If you want to upgrade your outdated dynamometer data acquisition system, or you are looking for a measurement system for a newly built dyno, contact me. I will certainly offer a solution that will meet your needs.

Dyno Controller

Top-end controller for most advanced dynamometers. Supports 4WD chassis dynamometers without mechanical synchronization and 4WD hub dynamometers. Many inputs and outputs allow connection of additional sensors and actuators.

Dyno Controller

Affordable controller for budget dyno builds. Despite its decent price, it supports braked dynamometers, engine dynamometers, and 4WD chassis dynamometer with mechanical synchronization.

Brake Interface

High-speed eddy current brake power supply with fast demagnetization and 3 phase mains power supply. Absorber current can be controlled via CAN bus or PWM digital signal.

  • Power corrections with included ambient conditions sensor (weather station): DIN 70020, EC 95-1, ISO 1585, JIS D1001, SAE J1349, SAE J607, EEC 80/1269.
  • OBD2 support via USB or Bluetooth adapters. Programmable data logging.
  • IP camera run recording and monitoring.
  • Engine knock detection from knock sensor signal.
  • Total 14 outputs for control of peripheral devices in your dyno test cell.
  • Powerful data logging with total of 27 inputs. In AWD hub dyno 19 inputs are left spare for additional sensors!
  • 2x CAN-bus interface for system expansion with external modules. Input and output messages fully programmable.
  • ECU data logging via CAN-bus. 26 ready-made ECU presets available.
  • High precision 16bit analog inputs.
  • Speed inputs resolution: 32ns (0.000000032s)
  • High sampling frequency: 500Hz for analog inputs, 1000Hz for speed inputs.
  • Fast absorber control loop running at 1000Hz frequency.
  • Fast eddy current brake power supply:
    • Typical full current in 0.2s and back to no current in 0.02s!
    • Closed loop current control with CAN-bus diagnostics.
    • 1-phase or 3-phase supply.
  • Digital speed synchronization between rollers or wheels.
  • Automatic loss measurement to calculate torque and power at engine.
  • Customizable reports. Page orientation, plots size, visible parameters, company information and logotype can be personalized.
  • Engine speed can be calculated or sampled from inductive clamp, OBD interface or CAN-bus.
  • Functions system for custom channels calculation and automation of outputs control.
  • Analog inputs fully programmable with interpolation table allows connecting of any analog sensor.
  • K-type thermocouples can be connected directly.
  • Data channels monitoring with warnings and alarms.
  • Throttle control with programmable sequences.
  • High compatibility with existing absorber. It can be controlled via analog output, PWM signal or CAN-bus.
  • Powerful DSP signal filtering / averaging / smoothing. Fully programmable to remove unwanted noise or vibrations.
  • The system can be remotely controlled via CAN bus to allow integration with other systems in your dyno test cell.

Why chose PEREK products?

I founded the PEREK company in 2019 based on many years of experience in mechatronic engineering and electronic systems design at ECUMASTER. I constantly expand the offer in the field electronic solutions for dynamometers and create products both for professional testing rig and for hobbyists who want to inexpensively equip their own dyno with a new data acquisition system.
As a motorsport and modern technology enthusiast, I take care to meet the needs of my customers both in terms of electronic devices and the provided software.

During my years of experience with dynamometer upgrades, I gathered both first-hand experience and feedback from my customers with upgrades of dynamometers:
Bosch FLA 203, Bosch FLA 206, SUN / Maha LPS 2000, Hofmann Dynatest, Mustang, Dynocom, Dynomite / Land and Sea, Dynomax, Dimsport, Vtech, Dynoproject.

I also have experience with eddy-current absorbers (retarders) from Frenelsa, KLAM, Telma, Pentar Kloft, KEAO, Schenck, Borghi & Saveri, Elektromex
and with water brakes.

Even if you want to upgrade a dyno I never heard of, a few pictures of the hardware and some info will be enough for me to help you with the upgrade.
