TREK Product - Model 605A High Voltage Power Supply

TREK Model 605A High Voltage POWER Supply

The Trek Model 605A is a high voltage power supply and reference supply designed to provide precise control of output voltages in the range of 0 to +1 kV DC or 0 to -1 kV DC with an output current range of 0 to ±1 mA DC.

The Model 605A provides two modes of operation, a fixed mode providing a constant +1 kV or -1 kV output, and a variable mode providing variable control of the output voltage with a one (1) volt resolution over a range of 0 to ±1 kV.

The Model 605A features an all-solid-state design for accurate, low-noise operation and is protected against over-current conditions that may be generated by output short circuits to ground.

A Digital Enable feature provides a connection for a remote device to turn on and off the high voltage of the instrument. This makes the 605A suitable for automated or computer-controlled systems.

The 605A is designed to be operated on a bench top.

PRODUCT FEATURES

Front Panel Voltage Controls

Mode Selection
Toggle switch to select either fixed or variable output voltage.

Fixed Voltage Selection
Select either +1 kV or -1 kV using the polarity switch when the mode switch is in the fixed position.

Variable Voltage Selection
Calibrated 10-turn dial.

Polarity
Three-position toggle switch. In the center position the output terminals are disconnected from the high-voltage supply and a 10 kΩ, 2 W resistor is placed across the output terminals.

Digital Enable Feature
A rear panel BNC providing a connection for remotely turning on and off the high voltage output of the 605A.

Recommended Connection
A switch, a relay, or the output of a switching device, such as an open
collector transistor, connected between the center conductor and
shield of the BNC. The high voltage will be turned off when this connection is open. The high voltage will be turned on when this connection is closed.

Current Limit
1.2 mA. An indicator will illuminate when the instrument is in a current limit condition.

GENERAL

Line Supply
Factory set for one of two ranges: 90 to 127 V AC or 180 to 250 V AC, at 48 to 63 Hz (specify when ordering).

Operating Conditions

Temperature
0 °C to 40 °C.
Relative Humidity
To 85%, noncondensing.

Dimensions
84 mm H x 254 mm W x 280 mm D, (3.3" H x 10" W x 11" D).

Weight
2 kg (4.4 lb).

High-Voltage Output Connector
Two (2) binding posts.

Digital Enable Connector
BNC connector.

AC Line Connector
Standard three-prong line connector.
