The 1500 watt FL Series breaks new ground in
regulated high voltage DC power supply technology. 1.5 KW in a 1U package is a
power density not typically seen in power supplies above 600V. The FL Series
provides this high power density up to an amazing 1.5 kV without the reliability
issues inherent in connecting multiple low voltage supplies in series to achieve
a higher voltage.
The FL Series offers the features you’ve come
to expect in a cutting-edge power supply. Some of the unique features are:
- Embedded microprocessor control with
RS232, RS485, and USB communications as standard features; full analog
remote capability is retained.
- A fully floating output isolated to 1500V
allows the user to select the polarity by choosing which side of the output
to connect to Ground.
- Field strappable parallel operation allows
the user to add additional units as required to increase the output power.
Sophisticated circuitry is designed to
withstand the most demanding applications with ease. Whether used in a
laboratory environment, industrial process such as plasma coating or beam
steering, the FL Series design benefits from our 30 plus years of application
engineering experience. The finished result of our efforts is a full-featured
power supply with conservative design, long life, and uncompromising
Compliance with RoHS and CE international
standards allows the user to integrate the FL Series into products as an
approved component, thereby reducing the burden placed on your Engineering and
Compliance departments as opposed to using non-approved items. Please take a few
minutes and read on, we have only touched the surface of FL Series’ broad range
Floating Output. Either output
terminal may be grounded for operation as a positive or negative supply.
Embedded Microcontroller control.
Front panel digital encoders provide high resolution local adjustment of voltage
and current program. Integral RS-232, RS-485, and USB communications
provide remote control program and monitor with 12 bit accuracy.
Remote Analog Interface. User
selectable 0-5V or 0-10V analog programming and monitors.
Field Strappable Parallel Operation.
Up to 4 identical supplies may be operated in parallel with user configurable
master and active current sharing.
Zero Space Stacking.

Ripple is less than 0.05% RMS of rated voltage at full load up to 1 MHz. Total
ripple and noise is less 0.2% p-p of rated voltage up to 20 MHz.
Voltage/Constant Current Operation.
Automatic crossover from constant-voltage to constant-current regulation
provides protection against overloads, arcs, and short circuits.
A rear panel switch allows selection of either current mode.
Fan speed control is adjusted automatically as a function of operating
temperature. This reduces noise and extends fan life.

circuitry senses the number of arcs caused by external load discharges. If
the rate of consecutive arcs exceeds approximately 2 arcs per second for at
least five arcs, the supply will turn off for approximately 2.5 seconds to
allow clearance of the fault. After this period, the supply will return
automatically to the programmed output voltage value with the voltage rise
time constant indicated. If the load fault still exists, the above cycle
will be repeated.
