Recalculates voltage/current limits automatically, forming a constant-power hyperbolic-shaped boundary between the voltage and current modes. The LXI-approved versions of the KLP model is a 1,200-W hyperbolic-limit programmable power supply.

Models with the 1.2K suffix provide the LAN port, which is an LXI-approved Class C Ethernet-based interface allowing multiple-user access via a standard Web browser. GPIB and isolated analog I/O are also provided.
