APS 3D Series Programmable AC & DC Electronics – High Power


The 3D Series AC & DC loads consists of a high power AC and DC capable load with support for up to 280Vac/400Vdc. This load offers a wider programmable Crest and Power Factor range than the 3C Series loads.


All 3D Series model loads share a common, modern user interface. Packaged in a compact 19” 4U chassis, 3D Series loads support up to 1875W True Power & 1875VA Apparent Power per chassis. The -EPF option hardware may be added to increase Apparent Power from 1875VA to 3700VA. For higher power requirements, 3D Series load can be paralleled using their standard Master/Slave mode. to support power levels up to 5625W/VA. Master/Slave configurations are controlled from the master front panel or remote control interface. The MODE Option allows automatic switching between 3P4W, 3P3W or 1P2W phase modes.
