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 a standard feature; 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 reliability.

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 of capabilities.

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.  1U rack mount supplies may be stacked with no space required between supplies.

Constant Voltage/Constant Current Operation.  Automatic crossover from constant-voltage to constant-current regulation provides protection against overloads, arcs, and short circuits. 

Cooling.  Fan speed control is adjusted automatically as a function of operating temperature.  This reduces noise and extends  fan life.

Input:  90-264 VAC continuous, single-phase, 48-63Hz. The RMS input current at rated power is less than 20 A @ 100 VRMS input and less than 11 A @200 VRMS input.  Output power is linearly de-rated from 100% to 90% between 100V and 90V input.

Efficiency:  84% typical at full load.

Output:  Continuous, stable adjustment, from 0 to rated voltage or current by panel mounted optical rotary encoder or by external, user selectable, 0 to +5V or 0 to +10V  signals.  Voltage accuracy is 0.5% of setting + 0.2% of rated.  Current accuracy is 0.5% of setting + 0.2% of rated.  Voltage and Current programming ranges are selected by switches that are accessible from the rear panel.  Optical rotary encoder resolution: 1V and 1mA with "Fine Adjustment" mode selected.  10 V and 10 mA with "Coarse Adjustment" mode (default).

Static Load Regulation: Max. 0.05% of Rating for full load to no load variation.

Ripple (RMS, 10 Hz - 1 MHz):  Max. 0.05% of rated voltage.  The ripple and noise are measured at the output connectors of the supply.

Stability: Max. 0.05% of rated over 8 hours time interval, following 30 minute warm up.

Voltage Decay Time Constant: Typical 45 ms time constant for an equivalent resistive load at the output of 33% of the rated full load.

Field Strappable Parallel operation:  Up to 4 identical units can be connected in parallel providing active current sharing with user configurable master - slave configuration.

Analog Current Monitor: User selectable 0 to +5 V or 0 to +10 V, equals 0 to Rated,  with an accuracy of .5% of reading + 0.2% of rated.

Resolution: 0.025% of full scale for both the voltage and the current channels.

Remote setting accuracy:  Voltage setting accuracy is better than 0.5% of setting + 0.2% of rated.  Current setting accuracy is better than 0.5% of setting + 0.2% of rated.

Remote reading accuracy: Voltage reading accuracy is 0.5% of reading + 0.2% of rated.  Current reading accuracy is 0.5% of reading + 0.2% of rated.
