The Model 5242 is a voltage-controlled power amplifier designed exclusively for Magtrol’s Model HD‑825 Hysteresis Dynamometer. Because of its double braking system, the HD‑825 requires more than 4 amps of power in order to reach full torque. The 5242 (which can provide up to 5 amps of output current) is necessary in order to amplify the power between the DSP7010 Controller (which has a maximum current output of 1 amp) and the HD-825 Dynamometer.
| Current Output | 0 to 5 A DC |
| Control Input | 0 to +3 V DC or 0 to -10 V DC |
| Fuses (5×20 mm) | Brake: UL/CSA IEC 6.3A 5A 125 250 VSB VT Power (120 V): UL/CSA 3A 250 VSB Power (240 V): IEC 1.25A 250 VT |
| Power Requirements | 330 VA |
| Voltage Requirements | 120/240 V 60/50 Hz |
If the HD-825 is purchased without a dynamometer controller, please inform Magtrol of your controller model—as it may be necessary to modify your existing controller so that it functions properly with the 5242 Power Amplifier.

[post_content] => Magtrol offers these calibration beam assemblies and weights for calibrating HD-Series Hysteresis Dynamometers. To perform a successful dynamometer calibration, precision weights heavy enough to apply a torque at or close to the full scale rating are required. Magtrol WT Series Calibration Weights are equal to the dynamometer's torque value, divided by the distance between the outer pin and centerline of the corresponding CB Series Calibration Beam. Calibration Weights are available in English or SI units. Calibration Beams are marked for both English and SI weights. For detailed dimension drawings, click on the model's underlined link. A PDF document will open in a new window.(Adobe Acrobat Reader 7.0, or later, is required.)
