Results from PID stress tests can be misleading when bifacial PV modules are PID-stressed from just one side using the foil method in IEC TS 62804, according to a new study by Belgian researchers. An ...

Self-regulating systems with feedback loops, i.e., the routing back of the output of a system to its input, have existed since antiquity and have since become an integral part of modern technology.

CS series process control modules enable PID loop control of any process without using a PLC. A variety of modules are available for temperature, flow, or pressure control. Single- and dual-loop ...

Plant engineers and technicians are frequently asked to tune the controller when a control loop’s process value has prolonged or significant excursions from the set point. But in many instances, no ...

JA Solar’s polycrystalline Riecium module has passed TUV SUD’s 500-hour potential induced degradation (PID) test. The tests involve exposing the panels to extreme conditions including 85˚C, 85% ...
