5242 – Power Amplifier

Product Description

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.

Specifications

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

Ordering Information

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.

With over 50 years’ experience in dynamometer design and torque measurement, Magtrol has revolutionized the industry. Magtrol’s new Micro Dyne, capable of measuring extremely low torques (2.0 mN·m can be resolved to 0.0004 mN·m), is designed exclusively for testing miniature and micro motors.

For the utmost convenience, the Micro Dyne is packaged as a complete motor testing system. Everything that is needed to accurately and efficiently test miniature motors and micro motors is included with the purchase of a Magtrol Micro Dyne. The only component that needs to be supplied by the customer is a laptop or desktop personal computer and a motor power supply.

                    [post_content] => Magtrol’s AMF Series Adjustable Motor Fixtures are used to secure small to medium-sized motors in place while running any test. These extremely versatile fixtures also enable easy motor centering for coupling to a Magtrol HD Series Hysteresis Dynamometer. (Couplings can be supplied upon request.) Various motor lengths are accommodated by either an attached T-slotted base plate or sliding base, depending on the model.

The AMF-1, -2 and -3 Fixtures feature one or two adjustable bridges, each fitted with a fluted knob clamp screw, to allow clamping anywhere along the axis of the motor. The adjustable bridge on the AMF-V Fixture incorporates a straight-line action clamp with a V-angle rubber padded clamp to maximize the mounting area.

To safeguard the motor, locking thumb screws provide protection against vibration and all motor-to-fixture contact surfaces are nylon padded for scratch-free clamping.
