The Techron 7570 is a precision power amplifier engineered for signal amplification across DC to over 20 kHz, with extended frequency capability to 45 kHz depending on application requirements. Operating in selectable Controlled Voltage (CV) or Controlled Current (CC) modes, it maintains stable output across varying load impedances. The amplifier delivers 1,018 W rms continuous average output power into 4 Ω loads with maximum output specifications of 64 V rms and 15.9 A rms. Its linear topology, low distortion characteristics (0.07% harmonic, 0.01% intermodulation), and comprehensive protection circuitry make it suitable for electrodynamic testing, shaker applications, and EMC environments. Multi-amplifier configurations and bridged operation are supported, with flexible front-panel input modules enabling system customization.
