                    [post_content] => DES 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 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 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 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 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 Series case has to be grounded and the use of a ground fault current circuit breaker is recommended.

Depending on the system configuration, a riser may be required to lift the transducer from the baseplate to the shaft height of the brake and/or the motor being tested. Magtrol RTM Riser Kits come complete with attachment hardware for the transducer and T‑nuts and bolts for attachment to the PT Base Plate.

                    [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] => Hysteresis Brake Dynamometers (HD Series) are versatile and ideal for testing in the low to medium power range (maximum 14 kW intermittent duty).  With a Hysteresis Braking system, the Dynamometers do not require speed to create torque, and therefore can provide a full motor ramp from free-run to locked rotor.  Brake cooling is provided by convection (no external source), by compressed air or by dedicated blower, depending on the model.  All Magtrol Hysteresis Dynamometers have accuracy ratings of ± 0.25% full scale — depending on size and system configuration.

Hysteresis Braking System: Provides precise torque loading independent of shaft speed
 	
Motor Testing from No Load to Locked Rotor
 	
Accuracy: ±0.25% (Full Scale)
 	
Air Flow Sensor: For protection against overheating and operator error
 	
Standard Torque Units: English, Metric and SI
 	
Custom Dynamometers: for special torque and speed requirements
 	
Easy Calibration

The Hysteresis Braking System
All Magtrol Hysteresis Dynamometers absorb power with a unique Hysteresis Braking System which provides frictionless torque loading independent of shaft speed. The Hysteresis Brake provides torque by the use of two basic components - a reticulated pole structure and a specialty steel rotor/shaft assembly - fitted together but not in physical contact. Until the pole structure is energized, the drag cup can spin freely on its shaft bearings. When a magnetizing force from the field coil is applied to the pole structure, the air gap becomes a flux field and the rotor is magnetically restrained, providing a braking action between the pole structure and rotor.

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 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 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 Series case has to be grounded and the use of a ground fault current circuit breaker is recommended.
