High Voltage Power Supply

The Model 3230 Reversible Polarity Power Supply consists of a standard rack-mounted control panel and an oil-insulated power supply rectifier tank. It is capable of supplying 35 kV dc at 10 mA and has a surge current rating of 50 mA.

Safety Lock Switch:

Provides Locked OFF condition to prevent unauthorized use.

Main Power On Circuit Breaker Switch:

Controls the power for the entire Control Panel and is in series with Safety Lock Switch.

Zero H. V. Control Indicator:

A red neon lamp lights when the High Voltage Control is not zeroed and an attempt is made to energize the high voltage circuit.

Interlock Open Lamp:

An amber neon lamp lights when the external interlock circuit is open and the Power Supply is ON (Main Power On).

Kilovolts Meter:

This meter indicates charging voltage at the Oil-Insulated H. V. Power Supply Rectifier Tank.

Milliamperes Meter:

This meter indicates charging current at the Oil-Insulated H. V. Power Supply Recitifier Tank.

Kilovltmater Range Switch:

A three-position switch which allows range sitching of the Kilovolts Meter to Low, Medium or High.

Output Polarity Switch:

This switch operates the reversing relay in the H. V. Power Supply and switches the polarity of the meters and over-voltage control diodes in the Control Panel to match the output selected. A Shunted Meter position is provided for use when the system is being transported.

Circuit Breaker Closed Indicator:

An amber neon lamp will light, indicating that the Main Power On switch has been closed.

Circuit Breaker Open Indicator:

A clear neon lamp will light, briefly, indicating that the Main Power On switch is open.

Negative and Positive Polarity Lamps:

An amber neon lamp will light, giving visual indication to confirm that the Output Polarity switch is closed in the position desired.

Milliammeter Range Switch:

A three-position switch allowing range switching of the Milliammeter to Low, Medium or High.

High Voltage Control:

The High Voltage Control is provided with a 0-100 logging scale. Advancing the control clockwise increases the high voltage output from the supply.

High Voltage-Off Switch:

Push-button switch de-energizes the high voltage circuit "crow-bars" the high voltage output.

High Voltage-Off Indicator:

A green High Voltage-Off lamp indicates when the high voltage circuit is not energized.

High Voltage-On Switch:

Push-button switch energizes the high voltage circuit when pressed.

High Voltage-On Indicator:

A red High Voltage-On lamp indicates that the high voltage circuit has been energized.

At the back of the Panel:

Warning Device Receptacle(non-polarized):

This receptacle supplies 120 V ac FOR EXTERNAL SAFETY EQUIPMENT when the High Voltage primary circuits are energized.

Overcurrent Trip Adjust:

This potentiometer sets the tripout current level for protection of the High Voltage Power Supply Rectifier Tank.

Caution:

Do not turn the H.V. Power Supply Control Panel OFF with the Safety Lock when the Pulser if charged. Permanent Damage to the Power Supply Transformer may result from transient currents. When the High Voltage Power Supply Control Panel's current meter is placed in the low range position, the Model 705 System should not be operated. The subsequent current surge could result in damage to the current meter.
