General Power Supplies

General-purpose AC and DC bench power supplies and digital power meters from MEWOI and LISUN, for straightforward laboratory, field, and educational power delivery needs.

Not every application needs the precision, dynamic response, or regenerative capability of our ActionPower and Preen test platforms. For basic constant-voltage and constant-current power delivery, general-purpose AC and DC bench supplies offer a simpler, more cost-effective option — well suited to educational labs, field service work, and general production tasks where straightforward, reliable power matters more than advanced test capability.

This range also includes LISUN's precision AC power sources and digital power meters, commonly used alongside lighting and LED test systems for low-distortion supply and accurate power measurement.
