Chroma 61511/12 series power sources

The Chroma 61511/12 series power sources provide 150/300 VDC and three-phase AC power to 90 kVA by paralleling. Precision PWM modulated voltage in the frequency range of 15 Hz to 1.5 kHz provides for commercial, military and avionics testing to a comprehensive suite of IEC regulations for regulation, flicker, harmonics, interharmonics, PLD, etc, further enhanced by programmable output impedance.

Operational features include programmable slew rates for voltage and frequency, phase angle control, programmable harmonics and non-periodic as well as interharmonics and arbitrary waveforms through external input. Power line disturbances can be tested as step, pulse and list modes. The measurement function permits harmonic analysis of current.

Control of menus is provided via graphical interface simulating conventional manual control panels, making the systems user-friendly. Interfaces include GPIB, RS 232, USB and Ethernet.
