[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] => 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 Powder Brake Dynamometer (PB Series) contains, as its name suggests, a magnetic powder. The electrical current passing through the coil generates a magnetic field, which changes the property of the powder, thus producing a smooth braking torque through friction. They are ideal for applications operating in the low to middle speed range or when operating in the middle to high torque range. Like Hysteresis Brakes, Powder Brakes provide full torque at zero speed. Like the Eddy-Current Brake Dynamometers, the PB series are water-cooled, allowing for power ratings up to 48 kW. The PB Dynamometers have accuracy ratings of ± 0.3% to 0.5% full scale, depending on size and system configuration.
Features
- 9 Models with Maximum Torque from 5 N·m to 1 200 N·m (3.69 lb·ft to 885 lb·ft)
- Braking Power: 500 W to 48 kW
- Stable Braking Torque
- Low Moment of Inertia
- Operation in Either Rotational Direction
- Braking Torque Measurement Integrated
- Integrated Optical Speed Sensor
- Special designs available upon request
Operating Principles
The PB Series - Powder Dynamometers contain, as their name suggests, a magnetic powder. The electrical current passing through the coil generates a magnetic field, which changes the property of the powder, thus producing a smooth braking torque through friction between rotor and stator. The Powder Dynamometers (PB) produce their rated torque at zero speed. The element to be tested can be loaded at standstill to determine the starting torque.
Optical Speed Sensor
Each PB Series Dynamometer has a standard optical speed sensor. PB 43 has an optical speed sensor with a 30 PPR (Pulses Per Revolution); PB 65, PB 115 & PB 15 has an optical speed sensor with a 60 PPR. For higher speed resolution in low speed applications, Magtrol offers a 600 PPR or 6 000 PPR encoder as an option.
