5502/5503 – Manual Dynamometer Switch Box

Product Description

Magtrol Models 5502 and 5503 are manually-operated switch boxes that permit the connection of up to three Magtrol Dynamometers to a single Dynamometer Controller. Use of the switch boxes facilitates quick and easy interfacing to multiple dynamometers without the need to disconnect and reconnect the brake and control cables. For Magtrol WB Eddy-current or PB Powder Brake Dynamometers, BOTH a 5502 AND a 5503 Switch Box are necessary. Magtrol HD or ED Hysteresis Dynamometers only require the 5502.

                    [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 410 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 410 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.
