AC Sources
Programmable AC power sources and frequency converters, including 400 Hz aircraft ground power — integrated and supported by Intepro, built by our supply partners.
Supplying power and testing against a standard are different purchases. A source that holds nominal beautifully may be unable to run a single transient clause, and no amount of headroom compensates for the absence of programmability.
The range here runs from bench units through cabinet systems to regenerative grid simulators, including 400 Hz work for aerospace and defense. Catalogues differ on what to call them — programmable AC power supply, AC power source, AC source — and they mean the same instrument.
Intepro selects, integrates and supports these sources rather than manufacturing them. Every product page names its manufacturer, because you should know whose revision notes to follow.

Choosing between them
Size on peak, not RMS
Transient envelopes reach well above nominal. A source chosen on steady-state headroom will clip the surge, and a clipped surge is a different, easier test.
Ask about reverse energy
Motor-type equipment pushes energy back. Not every source tolerates it, and for actuator or drive work this is pass/fail rather than preference.
Fixed or programmable frequency
Variable-frequency platforms need a programmable range and a programmable rate of change, not a source that happens to reach the endpoints.
