The Enclosure / Power Supply houses control and sensing devices used in power electronics circuits. The more compact modules are of the plug-in type and designed to be inserted in the Enclosure / Power Supply, where they are powered automatically.

The Enclosure / Power Supply includes a permanently mounted dc power supply that is fully protected against short circuits and overloads. Prewired backplane connectors route power to the individual plug-in control modules. Electric Power is automatically applied to the plug-in control module, when fully inserted into any slot of the Enclosure / Power Supply.

Three dc voltages are available from the power supply: +15 V dc, -15 V dc, and +5 V dc. These three voltages are also available at the front panel, terminated by 2 mm banana sockets. A light-emitting diode (LED) indicator for each voltage supply will turn off when the supply goes into an overload condition due to equipment malfunction or faulty power connection to external equipment.
