Electronic Component (Power Source)
SL series is intended for installation as a component of a system. It is designed to meet CE standards, with conditions of acceptance often being: customer provided enclosure mounting, EMC filtering, and appropriate protection, and isolation devices. The SL series is not intended to be operated by end users as a stand-alone device. The SL series power supply can only be fully assessed when installed within a system, and as a component part within that system.

eSL Option
The eSL Option provides a vacuum fluorescent front panel display and Ethernet connectivity. Both the 1U (1.75”) and 2U (3.5”) SL product offerings are available with the eSL Option. Using the front panel local controls the main menu has the following features:
Local/Remote Control
Allows operation from either the local front panel or remotely via the Ethernet Category 5 connector.
Features Menu
Allows control over Adjustable Overload Trip and Slow Start features.
Tutorial Menu
Provides information on how to use the local front panel interface.
Diagnostics Menu
Provides information on the revisions of the hardware, firmware and IP address. Additionally the Diagnostics Menu provides information on the status of the internal low voltage housekeeping power supply voltages.
eSL Option power supplies can still be fully controlled via the SL’s comprehensive remote analog interface, so these units are fully backwards compatible with standard SL power supplies.
SL SERIES OPTIONS
AOL Adjustable Overload Trip
A control board jumper is moved to make the power supply shut down if it ever operates in current mode. This allows the user to set the current programming level as a trip point that will turn the power supply off with an Over Current fault if it ever tries to operate in Current Mode.
APT Adjustable Power Trip
A third control loop is installed in the power supply, a power loop. This power loop uses an analog multiplier chip to multiply the voltage and current feedback signals to create a power feedback signal. Programming and feedback scaling is 0-10Vdc = 0-100% of rated power. The circuit is configured to trip the power supply off with an Over Power fault if the power loop ever tries to regulate.
AT Arc Trip
A control board jumper is moved such that the first arc sensed will shut the power supply off with an ARC fault. BPM Bipolar Master
BPS Bipolar Slave
This option configures two identical but opposite polarity units to function as a single tracking bipolar supply. The voltage feedback of the master (positive unit) is provided to the voltage programming input of the slave (negative unit).
CMS Current Mode Select
A front panel switch is provided to allow the power supply to either regulate in current mode or create an over current fault when operated in current mode, which will shut down the supply. This is basically a switch selectable AOL option.
CPC Constant Power Control
Identical to the APT Option with the exception the power supply will run and regulate when the power loop becomes active.
DPM4 Digital Panel Meter, 4.5 digits
The standard 3.5 digit front panel meters are replaced with 4.5 digit panel meters.
EFR External Fault Relay
A set of relay contacts are provided via the rear panel interface that will change state if the power supply shuts down due to a fault condition.
eSL Ethernet Connectivity/VFD Front Panel
The eSL Option provides a vacuum fluorescent front panel display, Ethernet connectivity and comprehensive front panel controls.
FCV Fine Control Voltage
This option adds a second potentiometer to the front panel of the unit. This allows for a finer local adjustment of the output voltage setting.
FG Floating Ground
All the analog returns inside the power supply are isolated from chassis and brought to one point on the rear panel. Any current that flows out of the power supply via the HV cable/connecter on the high side must return back to the multiplier via the load return on the low side. With only one path to flow through on the low side, a current meter can be inserted in series and a safe ground referenced measurement can be made of the actual high voltage output current.
FGLL Floating Ground Low Leakage
Identical functionality as the FG Option but a shield is placed around the high voltage multiplier to capture any leakage current inside the power supply and return it to the top of the current sense resistor. This negates any internal leakage currents from effecting measurements being made.
IO Instant On
A jumper is placed between TB1-15 and TB1-16 on the rear panel, causing the power supply to automatically toggle into HV ON when ever the line voltage is applied.
LL(X) Lead Length
Extra long high voltage output cable. 20, 40, 60 and 100 feet are standard lengths.
LR Low Ripple
Done on a case by case basis, the standard unit is evaluated and modifications are done to improve the output ripple to 0.05% peak to peak. The operating frequency might be increased, or additional filtering may be added to the HV multiplier.
NAD No Arc Detect
This option removes the arc intervention circuitry from the power supply. Care must be exercised when using this option as damage to the HV multiplier could occur.
NSS No Slow Start
The standard 6 second long linear ramp of output voltage is removed allowing the high voltage to “step” to its set point when enabled.
PN Positive/Negative
Reversible polarity option. Units that are not inherently reversible by design (10kV to 130kV) can have their output polarity reversed by the process of exchanging the high voltage multiplier section.
RFR Remote Fault Reset
This option provides the ability to reset any power supply faults that might occur via toggling a signal on the rear panel interface.
ROV Remote Over Voltage
The programming signal for the over voltage comparator circuit is made available to the customer remotely, allowing the power supply to be set to trip the OVP circuit anywhere from 0 -110% of rated output voltage.
SL Slides
Industry standard rack mounted slides are installed on the power supply.
SS(X) Slow Start(X)
The standard slow start is modified to provide a time of (X) seconds. Time frames of 0.1 seconds to 120 seconds can be accommodated.
There may be some restrictions on multiple option combinations. Please contact our Sales department for more details.
