150 Volt to 2kv Power Supplies

The Elgar Isolation / Polarity Reversal Chassis provides programmable normal or reverse polarity DC voltage for high voltage and high power loads. The unit is designed to connect and operate with the Ethernet user interface of a Sorensen programmable DC power supply such as the SGA or SGI series to provide a switched output. The unit includes controls for AC input Power, Output Isolation, Output Polarity, Output Interlock and Remote Sense relay control. The internal relays of the isolation/polarity chassis are controlled through the external user interface logic originating in the SGA/SGI series power supplies with an Ethernet Programming Interface (Option 1C). The chassis consists of a four (4) main power relays that switch the DC power supply voltage to provide full isolation when open and normal polarity or reversed output polarity when closed with the Ethernet controller. The front panel of the Isolation / Polarity Reversal Unit includes an AC power switch that connects the AC input on the rear panel connector to an internal power supply that powers the relays. The unit includes an interlock connector that must be shorted before any relays will energize. All other controls are made through a cable connecting the SG Power Supplies External User connector on the Ethernet interface to the Isolation/Polarity chassis rear panel control connector. LEDs on the front panel of the chassis will change in response to the relay control status. The relays are interconnected so that if both isolation and polarity relays are enabled at the same time, the output contactors will be disabled to guard against shorting the output of the SG power supply. The Shutdown signal on the interlock connector also provides a way to interlock the chassis to the SG supply. This signal is connected to the S/D input of the supply and if the Interlock connection is opened, the signal will also disable the SG power supply through its Shutdown Input line. The Fault LED on the front panel indicates the status of the Fault line coming from the SG power supply. When the SG power supply is enabled, the DC voltage will be connected from the power supply to the Input connector on the rear panel. This input is connected to four power relays in a bridge matrix so that when one pair of relays are energized, the input power is connected to the output terminals with normal polarity. When the other pair of relays are energized, the input power is connected to the output terminals in a reversed polarity. The remote sense relays operate in conjunction with the isolation and polarity relay control signals so that the voltage can be sensed either remotely or at the input terminals of the chassis. Rack slide provisions on chassis side panels or rack support brackets. (Mounting hardware not provided).

Kepco precision, bench / lab, regulated, variable bipolar DC power supply / amplifier with analog volt / amp metering. In Kepco's BOP, the voltage and current outputs can be controlled smoothly and linearly through the entire rated plus and minus ranges, passing smoothly through zero with no polarity switching. BOP are high speed power operational amplifiers that can be used to provide dynamically agile voltage for test and simulation. BOP, while fully rated power supplies, are also high-powered operational amplifiers with full 4-quadrant, bipolar operation. Their output is capable of both sustained dc and the replication of arbitrary ac waveforms. They are not general purpose power supplies. By the nature of the bipolar high speed design, they do not have any energy-storage noise discriminating output capacitors. To realize the full high speed potential of BOP, the load characteristics should be mainly resistive. If the load is capacitive, (0.1 microfarad), the BOP must be slowed to avoid oscillation. This is accomplished in voltage mode by increasing the value of the feedback capacitance. Special terminals on the user port are available to slow the BOP for optimum current-mode stability into inductive loading. Includes copy of operation manual. Voltage stabilizing of current stabilizing modes. 40W linear 4 quadrant operation, FET output stage vacuum tube regulator - (8) 8068 tubes.
