Laboratory Power Amplifiers & Signal Sources

AC, DC, bidirectional, and grid-simulation power supplies from Preen and ActionPower, spanning compact bench-top sources through to megawatt-scale regenerative platforms. Whether you're validating a PV inverter's I-V curve response, cycling an EV battery pack, simulating a 400Hz aircraft ground supply, running grid-code compliance testing, or building a full production line, the right platform comes down to power range, dynamic response, and whether energy needs to be recovered rather than dissipated as heat. Browse the 10 categories below — organised by application rather than by brand — to find the configuration that actually matches your test requirement.
