EA-PS 2042-20B 320W Programmable Desktop DC Power Supply (Ordering Number: 39200114)

The EA-PS 2042-20B is a programmable desktop DC power supply in the 2020-upgraded EA-PS 2000 B TFT series (replacing blue LCD models). It has a color TFT display, improved USB port, and supports ModBus RTU/SCPI, fitting labs, R&D, workshops, electronic testing, education, aging tests, and industrial use. As a 320W unit, it offers continuously adjustable 0-42V voltage and 0-20A current for high-demand loads.

It ensures stable performance: voltage load regulation <0.15%, line regulation (±10% ΔU AC) <0.02%, accuracy <0.2%; current load regulation <0.05%, line regulation <0.15%, accuracy <0.3%. Voltage ripple is <150 mV PP (HF, 20MHz)/<2 mV RMS (LF, 300kHz), current ripple <15 mA PP (HF)/<6 mA RMS (LF). It accepts 90...264V AC (45...65Hz, PF=0.99) for global use.

Safety features include adjustable OVP (0...46.2V), OCP (0...110% nominal current, immediate shutdown), and OTP. A front USB port enables remote control via custom apps (LabView VIs available) or included "EA Power Control" (Windows, supports multi-device management, SCPI/ModBus commands, firmware updates, "Sequencing"). Paid options add trend visualization and Multi Control (20 units max).

It uses fan cooling for high-power operation, with closed top/bottom chassis (no external heatsinks, safe for education) and front safety sockets. U/I Flexiranging adjusts voltage/current to avoid exceeding max power (P=U*I). Measuring 174x82x320mm and weighing 2.3kg, it has 85% efficiency, ideal for Laboratory/R&D/Aging Test DC Power needs.
