Amplifier Controller HV-AMP-CTRL
Controller Module for High-Voltage Bipolar Power Supplies / Amplifiers With up to 5 Channels and an Optional Current Monitor

Jump to: Technical Data Download Additional Information

This amplifier controller is intended to manage the operation of up to 5 amplifier channels. Optionally, one channel can be replaced by a high-sensitivity current monitor. The amplifier controller is equipped with a USB and/or a LAN data interface. They allow to transfer measurement and settings data to or from the device and to control it remotely.

The device contains a microcontroller that provides the human interface, controls the USB and LAN data interfaces, and executes several monitoring tasks. It also controls the digital-to-analog converters driving the amplifiers. Additionally, the controller contains monitoring circuits for the amplifiers and the power supplies. They are based on analog-to-digital converters that measure the output and supply voltages. Optionally, one analog-to-digital converter measures the output of the current sensor.

The device monitors an interlock loop that disables the outputs if it is opened. The interlock loop is typically connected to a vacuum controller, it is intended to disable the device if the vacuum pressure exceeds a certain value above which discharges might occur. The connected amplifiers and their power supplies are typically cooled by a heatsink located on the rear panel. The heatsink is passively cooled, the controller unit monitors the heatsink temperature. The connected amplifiers are disabled if the heatsink threatens to overheat or if the temperature sensor fails.

The actual settings of the output voltages and other operation parameters are stored in a non-volatile memory and are automatically restored at the next device startup.

The USB or LAN interface can be used to remotely control the device by simple Windows™ programs. These utilities can also obtain hard copies, i.e. save the current LCD contents to a bitmap file at the host computer. Alternatively, you may write your own user software based on the supplied software interface. Upon request, a software interface for LabVIEW or other development systems is available. The USB interface can also be used to upgrade the firmware.
