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 DSP7000 Dynamometer Controller has been designed to work with the DES Series. 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. The main supply voltage of the DES Series is in the 115/230 VAC – 50/60 Hz range.
