Chroma 61512 Programmable AC Source

Overview

The Chroma 61512 is a programmable AC power source featuring state-of-the-art PWM technology. It delivers output voltage up to 300 VAC and frequency from 15 Hz to 1500 Hz, with an 18 kVA power capacity. The unit supports both single-phase and three-phase output, as well as AC+DC output modes, making it suitable for comprehensive power supply testing applications.

The 61512 is capable of delivering up to 4 times peak current compared to its rated capacity, with pure sine waveform output featuring typical distortion less than 0.3% at 50/60 Hz, making it ideal for testing inrush currents and transient power requirements.
