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

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.

                    [post_content] => Eddy-Current Brake Dynamometers (WB Series) are ideal for applications requiring high speeds and also when operating in the middle to high power range. Eddy-Current Brakes provide increasing torque as the speed increases, reaching peak torque at rated speed. The dynamometers have low inertia as a result of small rotor diameter. Brake cooling is provided by a water circulation system, which passes inside the stator to dissipate heat generated by the braking power, providing high continuous power ratings (max. 140 kW). WB Series Dynamometers integrate a torque measuring system with accuracy ratings of ± 0.3 % to ± 0.5 % full scale, depending on size and system configuration.

Features

  • 12 Models with Maximum Torque from 400 mN·m to 560 N·m (56.6 oz·in to 413 lb·ft)
  • Braking Power: from 500 W to 140 kW
  • Stable Braking Torque, without Shock
  • Low Moment of Inertia
  • Low Residual Torque
  • Operating Direction CW / CCW
  • Braking Torque Measurement Integrated
  • High Rotational Speed (≤ 80 000)
  • Integrated Optical Speed Sensor
  • Special designs available upon request

Operating Principles

The WB Eddy-Current Dynamometers develop their full power at high rotation speeds. The WB Series is particularly intended for motors which rotate at high speeds, up to 80 000 rpm (up to 100 000 rpm with WB 23 / 27; see specific datasheet). The braking torque depends on the rotation speed. Optical Speed Sensor Each WB Series Dynamometer is equipped with an optical speed sensor. WB 32 is equipped with a 4 PPR (Pulses Per Revolution) encoder, WB 43 and WB 65 HS are equipped with a 30 PPR encoder; WB 65, WB 115 & WB 15 are equipped with a 60 PPR encoder.
