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] => Originally designed to test window lift gear motors, Magtrol’s FMF Series Fixed Motor Fixtures are used to secure motors in place while running any test. These versatile fixtures align the motor under test with Magtrol’s HD-100, HD-106, HD-400, HD-500, HD-700 and HD-800 Series Dynamometers for easy setup and coupling—couplings can be provided upon request. Various adaptor rings (sold separately) can be customized to allow several different motors to be tested on the same fixture.
FMF Fixed Motor Fixtures can be mounted to any Magtrol Dynamometer T-slotted long base plate or any Hysteresis Dynamometer Table with grooved table top (TAB 1457S, TAB 0800L and TAB 0825L). These fixtures are equipped with a precisely located rectangular key on the bottom of the plate for easy centering. Also included are four adjustable clamping levers and T-nuts.

[post_content] => The PC-150 Polarity Changer uses Magtrol’s M-TEST 7 Software to remotely switch the polarity of a DC power supply in order to reverse the direction of the motor under test. When switching polarity, the voltage sense lines will also change in order to maintain the proper polarity on the power supply sense terminals.
