LVA Series Of 2-/4 Quadrant Amplifiers
SPITZENBERGER & SPIES
LVA SERIES OF 2-/4 QUADRANT AMPLIFIERS
AUTOMOTIVE SUPPLY SIMULATION AT IT´S BEST
The 2-/4-Quadrant Amplifier LVA is a new technically extended programmable voltage source for the automotive supply simulation of 12V, 24V and new 48V supply systems, maximum voltage 70V.
It’s technical specifications are designed for compliant testing according to ISO (7637, 16750), OEM (LV124, LV148) and many manufacturers specifications.
Highlights:
• Extremely low harmonic distortion – even under very non-linear load conditions
• Very fast slew rate > 20V/μs
• Operates from DC up to 50kHz large signal bandwidth (-3dB)
• Small signal bandwidth up to 300kHz
• High short-term overload characteristic (for 30s)
• Very high peak-load ability (up to 200ms)
• Very low internal resistance
• Sink operation mode included – real 4-quadrant operation mode
• Touch panel operation 7” 800×480

The LVA 4-Quadrant Amplifier offers four standard voltage ranges:
•20VDC
•36VDC
•54VDC
•70VDC
With the built in oscillator unit the amplifier’s input signal can be:
•DC signal
•Sine wave
•Rectangular wave
•Triangular wave
•Ramp (amplitude sweep)
•User defined
Alternatively an external signal generator can be used.
For each voltage range the operating mode options can be selected.
With the option “OPD” (overvoltage protection device) the EUT’s supply voltage is monitored and the EUT is protected against very fast rising high voltage.
The LVA allows optionally specifying the amplifier’s internal esistance from 0 to 200mΩ in each mode of operation.
Optionally the sink mode capability can be disabled.CIAT
