TREK (Medina, NY) has introduced a new High Voltage Power Amplifier - Trek Model PZD350A - which offers:

• A large signal bandwidth of 250 kHz (-3dB).
• A small signal bandwidth greater than 350 kHz (-3dB).
• Bandwidth capability that is especially important in new piezo and piezo-stack applications, which require the high current levels.
• Fully protected output.
• DC stability, high speed and precise control of output voltages (DC or peak AC) in the programmable ranges of 0 to +/-350 V with an output current range of 0 to +/-200 mA (bipolar model); 0 to +700 V with +/-100 mA (unipolar model); 0 to -700 V with +/-100 mA (unipolar model).
• Applicability in aerospace, biotechnology, defense, military, power, energy, laboratory, instrumentation, semiconductors and electronics.
