Microprocessor Advantages

The internal microprocessor checks for proper circuit operation while supervising all
operating parameters. System diagnostics run when the unit is initially powered up.
The most recent power settings and conditions (such as output production) are
retained in non-volatile memory.

Displays

The displays on the passive panels as well as the control panels show power, current,
or voltage levels. (The displays show levels for unit A and unit B if this is a dual unit.)
They also display information about output, setpoint, interlock, bus fault,
overtemperature, arcs, and error codes.

Arc-Suppression Feature

The Pinnacle supply's arc-handling feature ensures the shortest arc recovery time in
the industry. With the arc-suppression feature enabled, the Pinnacle supply's hard-arc
detection time is less than 1 µs, and delivered arc energy is less than 10 mJ for a 10
kW inverter. (Depending on your unit's output configuration, the energy could be
significantly less than 10 mJ.)
Additionally, the arc-suppression feature enables you to implement preprogrammed
arc-handling functions during your normal process cycle and your target conditioning
cycle (TCC). In this mode the arc detect time and arc shutdown time are fixed by
target type (metal or nonmetal). But you may also customize your arc shutdown and
arc detect delay times by selecting the custom mode. Other parameters, including long
arc count limit and voltage trip level, are selectable through the Pinnacle Remote
Active Panel or a serial communications (Host) port.

Theory of Operation

The Pinnacle power supply is a sophisticated and intelligent DC power supply
designed exclusively for use in vacuum environments. Figure 2-1 on page 2-3 and the
following paragraphs outline the theory of operation.
