[post_content] => If currents continuously reach above 20 amps, an external sensor must be used. Magtrol offers three different types of external shunts for use with Magtrol Power Analyzers. The HA Series shunt, designed for power cable hook-up utilizing 3/8-16 screws, has an insulating base and can be mounted on conductive surfaces. The LAB Series shunt also comes with an insulating base, along with thumb screws for the power leads and knurled nuts on the sensing terminals. The FL Series is a relatively small bus, bar-mounted shunt with large end blocks. The comparatively large end blocks and short spacing aid in cooling and allow the shunt to operate in more extreme environments. All shunts are calibrated on equipment with current certifications traceable to N.I.S.T.

[post_content] => DES 410 Series Power Supplies are specially designed for the full range of Magtrol’s Eddy-current and Powder brake dynamometers with the design goal providing the best response time. The DES 410 Series supplies are packaged in an industrial housing made of cast aluminum. This offers superior protection against radiated emissions in order to avoid any disruption of the surrounding electronics modules. This housing must be installed directly on the test bench, next to the brake, as close as possible.
The DES 410 Series supplies can be controlled by digital signals and analog set point coming from peripheral electronics. The DSP7010 Dynamometer Controller has been designed to work with the DES Series.
Control
The Power supply can be switched ON by remote control. The STAND-BY signal enables the output current to be delivered. This excitation current is controlled by a set-point in the 0-10 V DC range. The nominal value of the excitation current is set by internal resistors. There are two discrete outputs for alarms (open collector). The first is the "Temperature Alarm". It will indicate if the cooling water of the Dynamometer or the inner temperature of the DES 410 Series are out of limits. The second is the "Electrical Alarm". It occurs when an over current or a short circuit is detected. The output current is immediately turned OFF and latched while the General Alarm Relay is set under its Alarm position. A low state for 200 ms of the Stand-by signal resets the latch.
For applications with TANDEM dynanometers, the DES 410 Series units also control the power supply of the electromagnetic clutch.
Supply Voltage
The main supply voltage of the DES Series is in the 115/230 VAC - 50/60 Hz range. No selection is required.
The DES 410 power supply features a galvanic insulation between the main circuit and the dynamometer power.
The DES 411 does not have galvanic separation. For safety reasons, the DES 410 Series case has to be grounded and the use of a ground fault current circuit breaker is recommended.

[post_content] => Finally… a Micro Dyne system designed specifically for your micro motors!
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 EMA Series Stand Alone Encoder provides a squarewave output on two channels for up/down counting or free-runmotor speed measurement applications. Each channel outputs the specified pulses per revolution of the encoder shaft, and is 90° phase-shifted in order to determine direction when used with the appropriate counter/timer DAQ board. The device incorporates an infrared optical switch and disk assembled into a rugged aluminum housing. The encoder is supplied with an 8 mm rectangular key for easy alignment to a Magtrol PT 25 Base Plate.
