The PL303 models achieve an exceptional power density for a linear regulated power supply by offering up to 94 watts from a ¼ rack 3U-sized casing. This gives it an unusually small bench footprint taking up less space on a crowded bench. For rack-mount applications, up to four units can be mounted into a single slot.
Despite their small size and linear regulation, these Aim-TTi models generate relatively little heat through an advanced phase-controlled pre-regulator. This gives it significantly higher energy efficiency than conventional linear regulated designs, mainly when supplying lower voltages. The internal heat sinks use fan-assisted convection cooling to remove the heat with minimal fan noise. For these models the maximum output voltage is 30V and the maximum output current is 3A. Three ports are available to choose from, PL303, PL303-P, or PL303-P(G).
