FRONT PANEL CONTROLS

PROGRAMMING PUSH-BUTTONS

ON
Stand-by push button. It works for generator section and for amplifier section with a status LED for each one

V-A
To select the amplifier working mode (current amplifier –
voltage amplifier). The selection is indicated by the LED lit.

“X”
push-button available for any additional functions on customer’s request. This command is repeated on the connector located on back panel and a LED shows the push button state

Mode
To select the working “Mode” as generator press on “Local” and GPAC – RS232 or as amplifier using EXT GEN function.
All functions are shown by switch-on of their “LED”

 

EXT. GEN – IN (BNC) Connector
Signal input (± 10 Vp) to be amplified within the limits of rated date – opto-insulated connector

Monitoring output connector 0 – 10 V

Output
Output plugs to use up to 5A of current

LCD
Show the set values when the DLS is on stand-by

Numerical Keyboard
Parameter output’s configuration in generator mode

 

BACK-PANEL CONTROLS

DIN Plug
For mains input 230 Vac up to 1200 VA; in alternative cable for 3-phase mains input

GPAC Connector
With signals 0 ÷ 10 V you can manage the remote mode or the output voltage and current regulation and by a TTL signal (0 / 5 V) ON condition or stand-by. It provides V and I feedback through 0 ÷
10 V signal.
All available signals are opto-insulated.

Connector X – Y:
It allows command duplication that it can be activated by push buttons X and Y allowing use by remote mode
Digital interface connectors

Output Plugs
They are available in models with output current over 6 A

GENERAL FEATURES

The linear amplifier for industrial purposes “DLA” is a very versatile device since it can amplify signals ranging from +10 V to –10V with a reaction time up to 8 V/µs on output. Featuring a voltage limiter and a current limiter, it can work both as current amplifier and as voltage amplifier. Application range is wide, including to amplify noises to be superimposed on EUT in order to evaluate their immunity against some mains noises.

 

For this purpose we show some diagrams being feasible with our amplifier as application examples.
