3) Power Entry Module
The
HV Rack
system is equipped with a filtered power-entry module, IEC 320/C20 inlet.
4) System Ground
The
UltraVolt HV Rack
system is equipped with a ¼” x 20-thread, ½”-long, 18-8, stainless-steel ground stud.
This is used for connecting the
HV Rack
power supply’s chassis to system ground.
5) Configurable Connector Plate
UltraVolt’s HV Rack
power supply is equipped with a configurable output plate for each channel. Each plate is
custom configured based upon customer requirement and consists of a high-voltage connector and high-voltage
return for each channel. Both connectors are isolated from chassis ground.
6) HV Output Connector
The standard high-voltage connector is an Alden B110US, rated 40kV (other connectors are available). This
connector is internally wired to the UltraVolt high-voltage-power-supply output for the indicated channel.
7) HV Return Ground Binding Post
The standard high-voltage return is a 2-way binding post, isolated from chassis ground. This connector is
internally wired to the UltraVolt high-voltage-power-supply return for the indicated channel. High voltage
return is referenced to earth ground through a 1k
Ω
impedance and clamped for electrical transients exceeding
+/-91V. UltraVolt recommends using a ring lug to secure the HV return so it cannot inadvertently become
disconnected.
8) Cooling Fan
The
HV Rack
power supply has four cooling fans mounted on the rear panel. Air is drawn in from the back and
is blown through the equipment.
9) Remote Control Connector
The
UltraVolt HV Rack
system is equipped with remote control capability via a rear-panel, 37-pin ‘D’ female
connector (Metal shell connected to the chassis). The
Remote/Local Selector DIP Switch
, when correctly set,
enables remote control. Active remote control is indicated by a green status LED on the rear panel (and by a
remote indicator on the front panel). Through remote control connection, each of up to four channels’ signals
can be individually controlled and monitored including the following: output enable, voltage programming,
current programming, voltage monitor, and current monitor. In addition, there is a ‘global output enable’ signal,
which will enable/disable all channels simultaneously.
10) Remote Control LED indicator
This indicator illuminates when remote control is enabled.
11) Remote Control Selector Switch
When correctly set, this switch enables remote control of the
UltraVolt HV Rack
power supply. Switch 2 ON
(on = 1), enables remote control. Switch 2 OFF (off = 0) disables remote control. Switch 1 is not currently used.
12) Rack Configuration Label
This label indicates which model of UltraVolt high-voltage power supply is installed in each channel of this
UltraVolt HV Rack
system.
