PSG-300 Power Signal Generator

For immunity tests according to IEC/EN 61000-4-16 (DC-300 kHz), IEC/EN 61000-4-19 and IEC/EN 61543 (1 kHz-150 kHz)

The PSG-300 contains a linear precision power amplifier with a wide bandwidth (DC-300kHz), suitable for all applications concerning fast alternating signals at high output power. The built in generator provides sine, square and triangle waves.
Communication between PSG-300 and PC is via USB connection. The application sofware is suited for general power generator applications and for immunity tests according to EN 61000-4-16 as well as to IEC/EN 61543. Short term tests are enabled by phase controlled switching of an external power source. The PSG-300 is equipped with a silent, temperature-controlled fan. Internal safeguards protect the amplifier from overheating and high power dissipation. They also assure protection against short-circuits and overload.

– Short circuit and overload protection
– Completely linear and low noise design
– Outstanding DC stability
– Temperature controlled silent fan
– Over temperature switch off
– Protection / Ready LED
– EUT-fail input
– EUT-monitor input

The number one choice for all applications with the need for fast and powerful signals,e.g.:
– Simulation of DC/AC supply lines
– Generation of magnetic fields with Helmholtz or similar coils
– Control of piezo actors
– Immunity testing according to EN 61000-4-16, IEC/EN 61000-4-19 and IEC/EN 61543
– Calibration devices etc.
