HP / Agilent 3615A Power Supply

The HP/Agilent 3615A is a 60 W single-output DC power supply engineered for benchtop electronic testing, development, and system integration in laboratory environments. It delivers stable, adjustable DC voltage from 0 to 20 VDC at 0 to 3 A, with dual-mode operation in constant voltage and constant current. Manual control via 10-turn potentiometers combined with remote analog programming (0–10 V input) and local/remote sensing capabilities makes it suitable for precision applications requiring load-independent stability and dynamic transient response.

Key Features

Adjustable current limiting and overvoltage protection safeguard devices under test

Front and rear output terminals support multiple connection topologies

Remote sensing compensates for lead-drop voltage losses in long cable runs

Isolated outputs with 240 VDC float capability; either terminal can be grounded

Programming linearity: 0.5% for both voltage and current channels

Convection-cooled design requires no forced-air cooling infrastructure

Typical Applications Benchtop power conditioning for component characterization, power amplifier biasing, LED and optoelectronic device testing, system power distribution in development environments, and prototype validation where stable, programmable voltage and current sources are essential.

Compatibility & Integration The 3615A integrates with systems requiring 0–10 V analog control inputs and supports floating output configurations for multi-supply topologies. Local meter displays support manual operation; remote sensing terminals enable voltage regulation at the load terminals, not the supply.
