The PLA Series was designed from the ground up for ATE and production test environments where vertical rack space translates directly to system cost. Multiple voltage models per power class — covering 60 V to 1,000 V — eliminate the need to stock multiple load types. Individual FET protection ensures that a single transistor failure does not propagate through the load module, minimising repair cost and downtime. Closed-case calibration via the front panel eliminates the logistical and cost burden of factory returns. The PLA Series carries RoHS 3 certification, extending its availability across all EU markets.
Industry's Smallest Footprint
Highest power density and current rating in the air-cooled load market — more test channels per rack unit than any competing product.
Broadest Voltage Selection
60 V to 1,000 V voltage models cover power supplies, batteries, EV bus rails and PV inverters in one product family.
Individual FET Protection
Isolated FET failure containment prevents cascading damage — improving system uptime and reducing mean time to repair.
Closed-Case Calibration
Front-panel calibration routine eliminates factory returns — dramatically reducing calibration downtime and annual logistics cost.
