1. Introduction
1.1 GENERAL INFORMATION
The Model DES 410 and 411 Power Supplies are designed for use with Magtrol's Eddy-Current
and Powder Brake Dynamometers. The DES 410 and DES 411 supply the current to the coils of
the brake within the dynamometer. They are controlled by an electronic peripheral, the Magtrol
DSP7000 High Speed Programmable Controller.
Note: The DES 41x is intended for use in an industrial environment and
meets the standard IEC 61326-1 class B / Industrial electromagnetic
environment. For the immunity test, a deflection +/-3% FSD and
+/- 6%FSD is admitted for each performance criteria A and B

SYSTEM CONFIGURATION
DESCRIPTION
DES 410 and DES 411 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 / DES 411 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 / DES 411 supplies can be controlled by
digital signals and analog set point coming from peripheral
electronics. The DSP7000 Dynamometer Controller has been
designed to work with the DES 41x.
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 0-10VDC
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 41x 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/DES 411 units also control the power supply of the
electromagnetic clutch.
Supply Voltage
The main supply voltage of the DES 410/DES 411 is in
the 115/230VAC/50/60Hz 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 41x case has to be grounded and the use
of a ground fault current circuit breaker is recommended.
