California Instruments 351TL Low Noise Linear AC Power Source 350 VA

Description

The TL Series consists of two models, 251TL and 351TL, both using linear technology. These units are ideal sources for special purpose AC power applications that require variable voltage and frequency at high frequencies and low noise and distortion levels. Both units provide single-phase output. With simple knobs used to set voltage, frequency and current limit, the TL Series provides an inexpensive source of low AC power. All TL Series power source models can be used in table-top mode or rack-mounted.

Using state of the art linear technology, the TL Series programmable AC power sources are ideally suited for applications where a low distortion, low noise sinewave is required Selectable input voltage ranges allow this power source to be used anywhere in the world to provide a convenient source of variable voltage and frequency power for testing and evaluating AC powered equipment. All common line voltage and frequency combinations are covered.

In addition, the frequency range extends to 8000 Hz, making these products suitable for both conventional and special purpose applications.

Accurate measurement functions are available as an option to eliminate the need for external test equipment in many test setups. Voltage, current, peak current, power, and power factor can be read directly on the large LCD display or over the bus.
