Polyamp Series diode box 12 to 21A 30V - 300V
The diode box is an accessory mainly for PU500 models but can be used with any other DC/DC converter or power supply. The advantage of using the diode box is that the series diode thermal losses can be put outside the converter and there is no need to derate the output current.
The PU500 models do not have built-in series diodes as a standard feature. To achieve redundancy, we can either supply this diode box or use a built in series diodes. When built in series diodes is used output current is derated. How much derating, depends on model.
