Power Options with Autotransformer
The Autotransformer E8005A is required for systems with:
Small or Large test head, if the primary voltage is 440V or 480V.
Large test head, if the primary voltage is 200V/208V AND power consumption exceeds 36kVA. Currently this is the case if more than 42 digital channel boards (of any type) are installed.
• Analog boards can be neglected.• 1 Additional Support Rack is equivalent to 5 channel boards. • Example: For systems with 2 Additional Support Racks up to 32 channel boards are
supported without the transformer.
The E8005A can be pro-actively ordered for large test head systems to allow for later upgrades.

AC/DC boards to different low voltages required by the TH boards. The DC/DC Power Unit modules are mounted to water-cooled heat sinks.
• Each card cage contains two identical DC/DC Power Units.
• A DC/DC Power Unit consists of two DC/DC conversion units which are screwed onto both sides of a common heat sink.
• DC/DC Power Unit generates voltages for the following modules: Channel boards, Analog module, Clock boards, Device power supplies and Control boards.

There are 2 DC/DC power units per card cage in the test head. Each DC/DC power unit occupies 2 slots.
Each DC/DC power unit is composed of two boards. Each board has 5 DC/DC converters mounted to one water-cooled heat sink. These DC/DC converters supply required voltages to all test head boards.
Each converter has sense lines that adjust the output level roughly to its nominal level (without control circuitry).
Output levels are monitored and regulated by monitoring circuits to nominal levels in case of load variations.
The temperature of the heat sink is measured. The contactor K1 is disabled as soon as the temperature exceeds 57°C.
Each DC/DC converter has an enable input, which is used to switch on/off the converter. A certain switching sequence is followed in order not to damage sensitive components (ADC and bus driver).
Universal DC/DC only powers up, if PinScale or BIST Assist cards are detected.
CAUTION: Putting the analog DC/DC in a digital card cage might damage the channel boards. See supply voltage difference in the table.

Functions of the Power Control Board:
Contains a DIS controller which is connected to all other DIS controllers in the system via the CAN Bus.
Powered by +5 V / ±15 V / - 12 V from the Rack Interface Board
The supply voltages are present as soon as the main breaker is ON. Thus, the diagnostic hardware is accessible even if the system was shut down by a hardware failure.
The State Machine provides a defined power ON/OFF sequence.
Controls and monitors the DC/DC converters on the DC/DC Power Units.
Monitors the temperatures (reference: 57 degree C) of all cards in each card cage.
